Abstract
In the prior art, IP-based sensor networks and proprietary-protocol-based sensor networks are managed in different ways, thus the server in the core network cannot access the proprietary-protocol-based sensor nodes directly. Meanwhile the gateways in proprietary-protocol-based sensor networks save a large quantity of the information of the sensor nodes. Considering the above, the present invention provides a uniform-describing way on the objects of the sensor nodes and a method for managing the sensor nodes and an apparatus thereof. The management server describes the objects which each sensor node contains in the sensor networks with node identifiers, group identifiers and object identifiers, wherein the sensor nodes communicating with one another have the same group identifier. Then the management server performs network management on the objects which the sensor nodes contain according to the node identifiers, the group identifiers and the object identifiers.
Description
A kind of method and its engineering device technique field for management of sensor node
The present invention relates to the server in sensor network, more particularly to sensor network.Background technology
Existing sensor network is the separate dedicated network in order to particularly apply and set up.However, with being more widely applied, for example, environmental monitoring, intellectual traffic control etc., multiple independent sensor networks need to interconnect synergistically to realize data acquisition and control.Integrated sensor network is intelligent information architecture, and provides sensor network service for different users, for example, human consumer, community organization, enterprise, government etc..
The use of existing communication network interconnection wide field sensor network is efficient and economical.First, because the access network and core network disposed are quite varied, for example, ADSL, GPRS, global system for mobile communications, CDMA, World Interoperability for Microwave Access, WiMax etc., deployment Chuan sensor Wang Network cost can be reduced, so that the deployment of acceleration sensor network.Secondly, the pipe provider that the operator of communication network can apply from traditional sensor network is changed into the key player that sensor network applies implementor.
International telecommunication union telecommunication's Standardization Sector uses ubiquitous network（Ubiquitous Sensor Network, USN) represent by the net loaded wide area of telecommunications sensor network.Ubiquitous network is the network and information architecture of generalities, after the scene and/or environment that its pair is connected with any object collected by sensor node or sensor tag are detected, are stored, handled and converged, form information or business, and these information or business are passed into anywhere anyone at any time.Ubiquitous network has been widely used in civilian application, including environmental monitoring, agricultural monitoring, Industry Control and automation, health application, home automation, intellectual traffic control, military affairs etc. now.
In existing ubiquitous network, sensor network is based on different agreements, such as ZigBee, Bluetooth, IEEE 15.4, or IP agreement etc..In other words, some sensor networks are that, based on IP agreement, and other sensor networks are based on proprietary protocol, that is, non-ip protocol, for example, ZigBee, Bluetooth, IEEE 802.15.4 etc..In ubiquitous network,
Sensor network based on IP agreement and the sensor based on proprietary protocol can coexist.Need to manage different types of sensor network in ubiquitous network.However, existing sensor network sets up respective management framework based on specific management agreement, for example, Zigbee sensor networks are based on proprietary protocol, and it uses Zigbee network layer-management scheme.And the sensor network based on IP agreement generally uses Simple Network Management Protocol（Simple Network Management Protocol, SNMP) it is used for network management, wherein, the sensor network based on IP agreement for example can be the Low rate wireless personal area network based on IPv6（IPv6 over Low power Wireless Personal Area Network, 6L0WPAN ).In other words, the existing main agreement for management of sensor network includes：For managing the Simple Network Management Protocol of IP-based sensor network and privately owned management agreement for managing the sensor network based on non-ip protocol.
, can be directly with the IP address and the object identity of managed object of the sensor node for based on the sensor network nodes in IP agreement（Object ID, OID) it is managed.And because of usually not IP layers of sensor node in the sensor network based on proprietary protocol, and these sensor nodes are all based on proprietary protocol, generally the sensor node based on proprietary protocol is managed using the node identification of sensor node and the OID of managed object.Because the sensor node based on proprietary protocol is different from the address format of the sensor node based on IP agreement, object factory mode is different, the agreement of network management is also different, therefore, sensor network based on proprietary protocol and the sensor network based on IP agreement can not intercommunications, that is, the management agreement in the Chuan sensor Wang Network domains based on IP agreement can not be accessed directly based on being managed node in proprietary protocol.
In the prior art, in order that the gateway in the sensor network based on IP agreement and the sensor network interconnection based on proprietary protocol, sensor network provides the function of related interconnection.Therefore, server is in order to manage the object based on the sensor node in proprietary protocol, in addition to knowing object identity and node identification, in addition it is also necessary to know the IP address of the gateway of corresponding sensor network.Therefore, the server in ubiquitous network needs to handle two kinds of object factory mode.Accordingly, it would be desirable to server network of the identification based on IP agreement in ubiquitous network and the network based on proprietary protocol, and both different object factory modes are handled, therefore, this mode is inefficient, also uneconomical.In addition, server is in order to access the sensor node in the sensor network based on proprietary protocol, it is necessary first to access the sensor based on proprietary protocol
The gateway of network, due to being that gateway carries out protocol translation, because needing the node preserved in managed node to represent and object identity that this also brings extra burden to the gateway in the server in ubiquitous network and the sensor network based on proprietary protocol on gateway.The content of the invention
In view of prior art has above mentioned problem, the present invention is proposed to be used to manage the sensor node based on IP agreement and the sensor node based on proprietary protocol by the way of unified in a kind of management server.
According to the first aspect of the invention, it is used for the method for management of sensor network in management server there is provided a kind of, wherein, the sensor network includes the sensor node based on IP agreement and the sensor node based on proprietary protocol, the described method comprises the following steps：The object included using node identification, group mark and object identity to each sensor node in the sensor network is described, wherein, the group mark for the sensor node being in communication with each other is identical；Shelter states node identification, described group of mark and the object identity, and the object included to the sensor node carries out network management.
According to the second aspect of the invention, it is used for the managing device of management of sensor network in management server there is provided a kind of, wherein, the sensor network includes the sensor node based on IP agreement and the sensor node based on proprietary protocol, and described device includes：Device is described, the object for being included using node identification, group mark and object identity to each sensor node in the sensor network is described, wherein, the group mark for the sensor node being in communication with each other is identical；Managing device, for according to the node identification, described group of mark and the object identity, the object included to the sensor node to carry out network management.
The advantage of the technical scheme provided using the present invention is as follows：The present invention provides a kind of effective, feasible transparent Managed Solution, the program need not change the existing framework and communication protocol of sensor network by extending SNMP agreements for the ubiquitous sensor network of wide area.
The invention is not particularly directed to specific sensor network, and it is the general solution being managed by telecommunications network to sensor network.Using technical scheme, it is to be also based on proprietary protocol based on IP agreements that management server, which needs not distinguish between sensor network, therefore, and the present invention with higher scalability, is more passed through compared with currently existing scheme
Ji is more efficient.
Because present invention utilizes communication network, therefore, the present invention brings great convenience for the deployment, topological structure control and management of the sensor network of wide area.
In addition, the present invention does not need the gateway in sensor network to safeguard managed object using a pair sensor network nodes marks and object identity based on non-ip protocol, therefore, the burden of the gateway in sensor network is also mitigated.Brief description of the drawings
The following detailed description to non-limiting example is read by referring to accompanying drawing, other features, objects and advantages of the invention will become more apparent upon.

Fig. 3 shows the device block diagram according to the specific embodiment of the present invention.
Wherein, same or analogous reference represents same or analogous steps characteristic or device/module.Embodiment
Fig. 1 shows the network topology schematic diagram according to the specific embodiment of the present invention.Fig. 1 shows the gateway 3 in the sensor network based on IP agreement and the sensor network based on proprietary protocol, and the sensor network based on proprietary protocol.In the embodiment shown in Fig. 1, sensor network based on IP agreement and the sensor network based on proprietary protocol are connected into core net by the telecommunications network based on IP agreement, are communicated with the management server 1 and domain name system server 2 in core net.Wherein, management server 1 is used for the node for managing the sensor network based on IP agreement in ubiquitous network, for example, sensor node 4a, also manages the node of the sensor network based on proprietary protocol in ubiquitous network, for example, sensor node 4b.Domain name system server 2 is used to parse sensor node 4a and 4b address.The management server 1 and domain name system server 2 shown in Fig. 1 is logic entity.In actual network configuration, management server 1 and domain name system server 2
In the network entity that a physics can be integrated in.
First, in step S20, the object that management server 1 is included using node identification, group mark and object identity to each sensor node in Ubiquitous Network is described.For the object in the sensor network based on IP agreement, and the object in sensor network based on proprietary protocol, management server 1 is used<Node identification, group mark, object identity ＞ is described.
Wherein, the group mark for the sensor node being in communication with each other is identical, it is referred to as a sensor node communication set for the one group of sensor node identified with identical group, both the sensor node based on IP agreement can be included in the communication set, the sensor node based on proprietary protocol can also be included.Each sensor node communication set has inherent management strategy, and management server 1 can carry out unified setting and management to each sensor node in the group.Group mark e.g. 12 bits, as shown in Table 1.Wherein 0 and FFF (16 systems）It is preserved for system configuration.
Node identification is, for example, the globally unique mark that equipment manufacturers etc. are distributed by each sensor node.The form of node identification can include Medium Access Layer address, application identities and the type identification of sensor node.Wherein, Medium Access Layer address is unique mark of sensor node.Application identities are the unique marks applied for distinguishing sensor, for example, it is to be used for environmental monitoring that the application identities, which are used to identify the sensor node, specific scene such as magnitude of traffic flow monitoring etc..And type identification is used for the type of distinguishing sensor node, for example, the type of the sensor can be sound transducer, chemical sensor, Magnetic Sensor, speed, acceleration transducer, optical sensor, heat sensor etc..
For example, when sensor node is registered to management server 1, the sensor node needs to register its node identification to management server 1, including such as application identities, type identification and Medium Access Layer address.When sensor node communicates with network or other sensors node, management server 1 needs to identify for the sensor node of system distribution group.
Object identity is used to name the object in sensor node.Object identity is for the specific object in distinguishing sensor node.For example, the current working condition of sensor node, it is sleep state, holding state or working condition, and the data that sensor node is gathered, such as temperature, speed, humidity, the attribute of sensor node in itself is can also be, for example, the information such as dump energy of sensor node.
Node identification group identifies object identity
AppIDl. Type 1. MAC 1 A1B 1.2.3.4.5.6.7.8
AppID2.Type2.MAC2 C3D 2.3.4.5.6.7.8.9
AppID3.Type3.MAC3 E5F 3.4.5.6.7.8.9.0 tables one show an example of the object factory mode of sensor node.Wherein,
AppIDl, AppID2, AppID3 points another1J represents 3 application identities, and Typel, Type2 and Type3 represent 3 types, MAC1 respectively, and MAC2 represents 3 different Medium Access Layer addresses with MAC3 respectively.
Then, in step S21, management server 1 obtains the node identification of sensor node.For example, some application server（Not shown in figure）Wish to inquire about the state of some sensor node, or management server 1 needs to reset the state of some sensor node, therefore, management server 1 needs to obtain the node identification for the sensor node for wishing inquiry or configuration.The node identification preferably includes application identities, type identification and the Medium Access Layer address of sensor node.For example, sensor node 4a node identification is AppIDl Typel MAC 1, sensor node 4b node identification is AppID2.Type2.MAC2
In step S22, management server 1 is according to the node identification, the local search IP address corresponding with node identification.
When management server 1 is communicated previously with the sensor node, therefore, prestored the IP address corresponding with the Medium Access Layer address of the sensor node in management server 1, therefore, management server 1 directly searches local database, obtains corresponding IP address.For the sensor node of the sensor network based on IP agreement, IP addresses are the IP address for having corresponded to the sensor node, and for the sensor node in the sensor network based on proprietary protocol, the IP address that management server 1 is found has corresponded to the IP address of the gateway of the sensor node in the sensor network based on proprietary protocol.
When management server 1 searches local data base, when not finding the IP address corresponding with sensor node, in step S23, management server 1 sends inquiry request to domain name system server 2.The query messages include the node identification of sensor node, for inquiring about
The IP address corresponding with the node identification.For example, the node identification for the sensor node 4a that management server 1 is obtained is AppIDl .Typel .MACl, according to the node identification, corresponding IP address is inquired about to domain name system server 2.In the present embodiment, illustrated so that management server 1 sends query messages to domain name system server 2 as an example.It will be understood by those skilled in the art that when the corresponding relation of node identification and IP address is stored in other servers or module, management server 1 can also be inquired about to these servers or module.
Certainly, step S22 is dispensed.For example, the synchronism in order to keep management server 1 and data in domain name system server 2, management server 1 can directly be inquired about without local data base querying to domain name system server 2.
Then, in step s 24, domain name system server 2 obtains the IP address corresponding with the MAC 1 of domain name AppIDl Type 1., and the IP address is fed back into management server 1 by domain name mapping.For the sensor node of the sensor network based on IP agreement, IP addresses are the IP address for having corresponded to the sensor node, and for the sensor node in the sensor network based on proprietary protocol, domain name system server 2 has corresponded to the IP address of the gateway of the sensor node in the sensor network based on proprietary protocol to the IP addresses that management server 1 is fed back.
It is below the sensor node based on IP agreement first with sensor node, such as is illustrated exemplified by sensor node 4a.
In step S25, management server 1 sends the request message based on Simple Network Management Protocol, for the object progress network management included to sensor node.
Management server 1 for example periodically can send the request message based on Simple Network Management Protocol to its administrative sensor node, can also the request based on other application server, the request message of Simple Network Management Protocol is sent to the administrative sensor node of the management server 1.Request message in the application server includes the sensor node for needing inquiry<Node identification, group mark and object identity>.The request message can be used for the object identity for inquiring about sensor node, for example, management server 1 needs to obtain the state of sensor node, or need sensor node to report its data gathered etc.；Or sensor node, for example, changing the state of sensor node, is such as configured to Data Collection state by request message also including the instruction configured to sensor node from holding state.
These request messages can be transmitted based on Simple Network Management Protocol.Simple Network Management Protocol is the procotol based on UDP, and it be used to monitor or manage one group of equipment being connected in computer network with network in NMS.Simple Network Management Protocol can be also used for send configuration and update or control data, so as to manage a system on one's own initiative.In the internet, all IP network nodes have each unique IP address, and the object that IP network node is managed can be identified with object identity.Each object identity is used to identify a variable that can be read or set by Simple Network Management Protocol.Therefore, in the present invention, by extending Simple Network Management Protocol, include request message<Node identification, group mark, object identity ＞ is more convenient for carrying out multiple sensor nodes in a communication set unified management.
When the sensor node in the sensor network that sensor node 4a is based on IP agreement, the request message based on Simple Network Management Protocol directly reaches sensor node 4a, then, in step S26, sensor node 4a is directly based upon Simple Network Management Protocol to the feedback message of management server 1, for example, feedback transducer node 4a state, or the data that are gathered of report sensor node 4a etc., or feedback transducer node 4a has carried out the response message of corresponding setting according to the configuration of management server 1.Certainly, according to different acknowledgment strategys, if for example, network settings postpone successfully to match somebody with somebody when sensor, when need not acquiescently be fed back, step S26 is dispensed.
Illustrated below by taking the sensor node in being the sensor network based on proprietary protocol as the b of sensor node 4 as an example.For example, sensor node 4b is when being based on IEEE802.15.4 agreements, in step S25, in, the gateway 3 where request message arrival sensor node 4b that should be based on Simple Network Management Protocol.Then, in step S26, in, gateway 3 directly can be converted to the request message based on Simple Network Management Protocol based on IEEE802.15.4 agreements, for example, right<Node identification, group mark, object identity>The encapsulation based on IEEE802.15.4 agreements is carried out, the request message based on proprietary protocol is then forwarded to sensor node 4b again.
Then, in step S27, in, sensor node 4b carries out response, for example according to acknowledgment strategy, feedback transducer node 4b state, data that either report sensor node 4b is gathered etc. or feedback transducer node 4b have carried out the response message of corresponding setting according to the configuration of management server 1.Certainly, according to different acknowledgment strategys, for example,
If network settings postpone successfully to match somebody with somebody when sensor, when need not acquiescently be fed back, step S27 is dispensed.
Then, in step S28, in, the response message based on proprietary protocol is converted to the response message based on Simple Network Management Protocol by gateway 3 again, and the response message then is fed back into management server 1 again.Certainly, if step S27, has been omitted from, step S28 is correspondingly also dispensed.Furthermore, it is to be understood that step S25-S26 and step S25 ,-S28, between not sequencing.
The present invention is transparent for the sensor node 4b in a of sensor node 4 in the sensor network based on IP agreement and the sensor network based on proprietary protocol, it is not necessary to which sensor node is made any change.
The present invention can allow the management server in ubiquitous network to pass through<Node identification, group mark, object identity>All objects managed are accessed, and in the prior art, for the network based on proprietary protocol, management server can only directly access the gateway of the network based on proprietary protocol.
Because what sensor network or multiple sensor nodes were managed typically to some purposes or purpose as one group, for example, safety, book keeping operation, trust management etc., is that each sensor node sets up a group mark and is more beneficial for being managed one group of sensor node.
When the node identification of sensor node preferably includes application identities and type identification, it can more intuitively reflect the purposes of the sensor node.
Group mark and node identification are mapped to an object identity by the management information bank of Simple Network Management Protocol, certainly, because a sensor node can correspond to multiple objects, therefore, and multiple objects may map to a pair groups of marks and node identification.
More than, embodiments of the present invention are described from the angle of systems approach.Hereinafter, from the angle of device block diagram, the present invention is specifically described.
Fig. 3 shows the device block diagram according to the specific embodiment of the present invention.Wherein, device 10 is located in the management server 1 shown in Fig. 1.Device 10 includes description device 100 and managing device 101, the second acquisition device 102.Managing device 101 includes the first acquisition device 1010 and dispensing device 1011.Wherein, only it is described device 100 and managing device 101 is that, according to different embodiments, other sub-devices are dispensed necessary to realizing technical scheme.
First, the object that description device 100 is included using node identification, group mark and object identity to each sensor node in Ubiquitous Network is described.For the object in the sensor network based on IP agreement, and the object in Chuan sensor Wang Network based on proprietary protocol, management server 1 is used<Node identification, group mark, object identity ＞ is described.
Wherein, the group mark for the sensor node being in communication with each other is identical, it is referred to as a sensor node communication set for the one group of sensor node identified with identical group, both the sensor node based on IP agreement can be included in the communication set, the sensor node based on proprietary protocol can also be included.Each sensor node communication set has inherent management strategy, and management server 1 can carry out unified setting and management to each sensor node in the group.
Node identification is, for example, the globally unique mark that equipment manufacturers etc. are distributed by each sensor node.The form of node identification can include Medium Access Layer address, application identities and the type identification of sensor node.Wherein, Medium Access Layer address is unique mark of sensor node.Application identities are the unique marks applied for distinguishing sensor, for example, it is to be used for environmental monitoring that the application identities, which are used to identify the sensor node, specific scene such as magnitude of traffic flow monitoring etc..And type identification is used for the type of distinguishing sensor node, for example, the type of the sensor can be sound transducer, chemical sensor, Magnetic Sensor, speed, acceleration transducer, optical sensor, heat sensor etc..
For example, when sensor node is registered to management server 1, the sensor node needs to register its node identification to management server 1, including such as application identities, type identification and Medium Access Layer address.When sensor node communicates with network or other sensors node, management server 1 needs to identify for the sensor node of system distribution group.Therefore, the second acquisition device 102 obtains the node identification and group mark of sensor node in registration.
Object identity is used to name the object in sensor node.Object identity is for the specific object in distinguishing sensor node.For example, the current working condition of sensor node, it is sleep state, holding state or working condition, and the data that sensor node is gathered, such as temperature, speed, humidity, the attribute of sensor node in itself is can also be, for example, the information such as dump energy of sensor node.
Table two shows an example of the object factory mode of sensor node.Wherein,
AppIDl, AppID2, AppID3 represent 3 application identities respectively, and Typel, Type2 and Type3 represent 3 types respectively, and MAC1, MAC2 and MAC3 represent 3 respectively
Individual different Medium Access Layer address.
Then, the first acquisition device 1010 obtains the node identification of sensor node.For example, some application server（Not shown in figure）Wish to inquire about the state of some sensor node, or management server 1 needs to reset the state of some sensor node, therefore, the first acquisition device 1010 needs to obtain the node identification for the sensor node for wishing inquiry or configuration.The node identification preferably includes application identities, type identification and the Medium Access Layer address of sensor node.For example, the node identification that sensor node 4a node identification is AppIDl Type 1. MAC 1, sensor node 4b is AppID2.Type2.MAC2.
Then, managing device 101 is according to the node identification, the local search IP address corresponding with node identification.
If managing device 101 is communicated previously with the sensor node, may then prestore the IP address corresponding with the Medium Access Layer address of the sensor node in management server 1, therefore, managing device 101 directly searches local database, obtains corresponding IP address.For the sensor node of the sensor network based on IP agreement, IP address is the IP address for having corresponded to the sensor node, and for the sensor node in the sensor network based on proprietary protocol, the IP address that managing device 101 is found has corresponded to the IP address of the gateway of the sensor node in the sensor network based on proprietary protocol.
When managing device 101 searches local data base, when not finding the IP address corresponding with sensor node, managing device 101 sends inquiry request to domain name system server 2.The query messages include the node identification of sensor node, for inquiring about the IP address corresponding with the node identification.For example, the node identification for the sensor node 4a that the first acquisition device 1010 is obtained is the MAC 1 of 1. Type of AppID 1., according to the node identification, managing device 101
Corresponding IP address is inquired about to domain name system server 2.In the present embodiment, illustrated so that managing device 101 sends query messages to domain name system server 2 as an example.It will be understood by those skilled in the art that when the corresponding relation of node identification and IP address is stored in other servers or module, managing device 101 can also be inquired about to these servers or module.
Certainly, the step of managing device 101 carries out local search is dispensed, namely, for example, in order to keep the synchronism of management server 1 and data in domain name system server 2, managing device 101 can directly be inquired about without local data base querying to domain name system server 2.
Then, domain name system server 2 obtains the IP address corresponding with the MAC 1 of domain name AppIDl Type 1., and the IP address is fed back into managing device 101 by domain name mapping.For the sensor node of the sensor network based on IP agreement, IP address is the IP address for having corresponded to the sensor node, and for the sensor node in the Chuan sensor Wang Network based on proprietary protocol, the IP address that domain name system server 2 feeds back to managing device 101 has corresponded to the IP addresses of the gateway of the sensor node in the sensor network based on proprietary protocol.
Hereinafter, it is the sensor node based on IP agreement first with sensor node, such as is illustrated exemplified by sensor node 4a.
Dispensing device 1011 sends the request message based on Simple Network Management Protocol, for the object progress network management included to sensor node.
Dispensing device 1011 for example periodically can send the request message based on Simple Network Management Protocol to its administrative sensor node, can also the request based on other application server, the request message of Simple Network Management Protocol is sent to the administrative sensor node of the management server 1.Request message in the application server includes the sensor node for needing inquiry<Node identification, group mark and object identity>.The request message can be used for the object identity for inquiring about sensor node, for example, management server 1 needs to obtain the state of sensor node, or need sensor node to report its data gathered etc.；Or sensor node, for example, changing the state of sensor node, is such as configured to Data Collection state by request message also including the instruction configured to sensor node from holding state.
These request messages can be transmitted based on Simple Network Management Protocol.Simple network
Management agreement is the procotol based on UDP, and it be used to monitor or manage one group of equipment being connected in computer network with network in NMS.Simple Network Management Protocol can be also used for send configuration and update or control data, so as to manage a system on one's own initiative.In the internet, all IP network nodes have each unique IP address, and the object that IP network node is managed can be identified with object identity.Each object identity is used to identify a variable that can be read or set by Simple Network Management Protocol.Therefore, in the present invention, by extending Simple Network Management Protocol, include request message<Node identification, group mark, object identity>, it is more convenient for carrying out multiple sensor nodes in a communication set unified management.
When the sensor node in the sensor network that sensor node 4a is based on IP agreement, the request message based on Simple Network Management Protocol directly reaches sensor node 4a, therefore, sensor node 4a is directly based upon Simple Network Management Protocol to the feedback message of management server 1, for example, feedback transducer node 4a state, or the data that are gathered of report sensor node 4a etc., or feedback transducer node 4a has carried out the response message of corresponding setting according to the configuration of management server 1.Certainly, according to different acknowledgment strategys, if for example, network settings postpone successfully to match somebody with somebody when sensor, when need not acquiescently be fed back, then sensor node 4a is without response.
When the sensor node in the sensor network that sensor node 4b is based on proprietary protocol, for example, being the gateway 3 where request message arrival sensor node 4b that should be based on Simple Network Management Protocol when being based on IEEE802.15.4 agreements.It is based on the IEEE802.15.4 agreements, for example, right that the request message based on Simple Network Management Protocol directly can be carried out protocol conversion by gateway 3<Node identification, group mark, object identity>The encapsulation based on IEEE802.15.4 agreements is carried out, the request message based on proprietary protocol is then forwarded to sensor node 4b again.In the present embodiment, illustrated so that proprietary protocol is Zigbee IEEE802.15.4 agreements as an example, it will be appreciated by those skilled in the art that, the proprietary protocol not limited to this, the agreement such as based on Personal Area Network, Ethernet can also be included, as long as the agreement has data link layer and Medium Access Layer.In the present embodiment, it is managed in communication network using Simple Network Management Protocol, it will be appreciated by those skilled in the art that, the different versions of Simple Network Management Protocol, such as SNMPvl, SNMPv2, SNMPv3 are applied to the present invention, simply slightly has difference in terms of the encapsulation format of packet, these are poor
The different essentiality content on the present invention does not produce influence, therefore will not be described here.
Then, sensor node 4b is according to acknowledgment strategy, carry out response, for example, feedback transducer node 4b state, data that either report sensor node 4b is gathered etc. or feedback transducer node 4b have carried out the response message of corresponding setting according to the configuration of management server 1.Certainly, according to different acknowledgment strategys, if for example, network settings postpone successfully to match somebody with somebody when sensor, when need not acquiescently be fed back, then sensor node 4b is without response.
Then, the response message based on proprietary protocol is converted to the response message based on Simple Network Management Protocol by gateway 3 again, and the response message then is fed back into managing device 101 again.
The present invention is transparent for the sensor node 4b in the sensor node 4a in the sensor network based on IP agreement and the sensor network based on proprietary protocol, it is not necessary to which sensor node is made any change.
The present invention can allow the management server in ubiquitous network to pass through<Node identification, group mark, object identity ＞ accesses all objects managed, and in the prior art, for the network based on proprietary protocol, management server can only directly access the gateway of the network based on proprietary protocol.
Because what sensor network or multiple sensor nodes were managed typically to some purposes or purpose as one group, for example, safety, book keeping operation, trust management etc., is that each sensor node sets up a group mark and is more beneficial for being managed one group of sensor node.
When the node identification of sensor node preferably includes application identities and type identification, it can more intuitively reflect the purposes of the sensor node.
Group mark and node identification are mapped to an object identity by the management information bank of Simple Network Management Protocol, certainly, because a sensor node can correspond to multiple objects, therefore, and multiple objects may map to a pair groups of marks and node identification.
