The present invention relates to a system and method for remotely managing sensor node software in a sensor network, and more particularly, to software (eg, application software) necessary for the operation of a sensor node in a ubiquitous sensor network (USN). , Drivers, etc.).

The sensor network arranges hundreds to tens of thousands of sensor nodes, so that the surrounding current state or situation information is collected by the deployed sensor nodes, and the sensor nodes collect the collected state or situation information (sensing information) around the sink node. Through a relay node, such as a gateway to the gateway, the gateway refers to a network for transmitting the sensing information back to the upper application server.

In such a sensor network, a plurality of sensor nodes are randomly arranged in a specific area, and information collected by the sensor nodes is delivered to and used by higher application servers. However, until now, the technologies related to sensor network have been studied centering on unit technology, and the research on the overall sensor network structure or remote management technologies for randomly arranged sensor nodes are not studied.

Currently, some techniques have been proposed as software remote management techniques for randomly deployed sensor nodes in the sensor network. Currently proposed software remote management technologies of sensor nodes are simply a method in which a remote management server remotely delivers software to sensor nodes. For example, Korean Unexamined Patent Publication No. 2008-0051033 (hereinafter, referred to as a related art) discloses a ubiquitous sensor network system and method for remotely managing software of a node. The prior art manages a sensor network based on a management node that communicates wirelessly with sensor nodes and information on sensor nodes (sensor node location information, type information, and the like), and receives the received information from a sink node through a gateway. A network management server that transmits sensing information to an application service server, an application service server that recognizes a situation for an application service through sensing information received from the network management server, and provides an application service when an application service is requested from the application; The management server stores and manages the ROM file of the software for each version according to the operation policy, and receives a node's information from the network management server, and transmits the ROM file of the stored software to the management node managing the corresponding nodes. In such a sensor network, the management server updates the ROM file from the development PC whenever the ROM file of the software is updated. If there is a need to download a ROM file of new software to a specific sensor node, the network management server transmits the information of the node to the management server, and commands the node to reset through the sink node. The management server then checks the management node that manages the sensor node and sends the ROM file of the new software to the sensor node through the management node. This updates the sensor node's software.

However, in such a conventional sensor network, the software remote management technology of the sensor node may cause a lot of problems when considering various manufacturers, various types of sensor nodes, and management aspects of the sensor nodes due to random placement. In other words, in consideration of various manufacturers, various sensor nodes, and locations of sensor nodes, the software of the sensor nodes is preferably managed in a distributed manner. In this case, the software of the sensor nodes is managed in a distributed manner. There is a need for software remote management of sensor nodes in a new way different from the prior art.

Accordingly, the present invention has been proposed to solve the above problems of the prior art, and the software of the sensor node is managed in a distributed manner, and the corresponding software as a management node or gateway that manages the sensor node when software update of the sensor node is required. The location of the stored server, and the managed node or gateway directly downloads the sensor node's software from the server and delivers it to the corresponding sensor node, effectively managing the software of the sensor node regardless of the manufacturer and type of the sensor node.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a sensor network to which the present invention is applied. As shown in FIG. 1, a sensor network may be configured in various applications, and sensor nodes may be operated according to an independent or cooperative operating procedure. Can be.

Sensor nodes can be randomly placed in a specific area, and each sensor node knows its own location and counterpart sensor nodes to communicate with each other through autonomous networking. Here, if there is no other sensor node in its lower end among the sensor nodes, it is called an end node, and a sensor node that transmits sensing information transmitted from the end node to an upper end is called a sink node. The sink node wirelessly communicates with the upper gateway 11 or the management node.

The gateway 11 or the management node manages the state of the sensor nodes located in the area in which it is responsible, and senses the sensing information transmitted from the sink node through the broadband convergence network (BcN) 12 through an application service server (BcN). (Not shown). Here, the broadband integrated network BcN may be an IP network. In addition, the gateway 11 or the management node, if a software update event for the sensor node in the area in which it is responsible, the sensor node management server 13 to the sensor node information (for example, manufacturer, product name, serial Number, software version and the combined information). In addition, the gateway 11 or the management node transmits location information (eg, IP information or URL information) of at least one software management server storing software corresponding to the corresponding sensor node from the sensor node management server 13. When received, the software is connected to the software management server 14 to download the software for the sensor node and delivers to the sensor node.

The software management server 14 stores and manages the latest version of software required for each sensor node for each manufacturer and product of the sensor node. In other words, when each manufacturer develops a new sensor node or a new version of the software for the previous sensor node, the new software stores the new software in at least one of the plurality of software management servers.

The sensor node management server 13 manages information (manufacturer, serial number, product name, etc.) of each sensor node, and also manages location information of each sensor node connected to the sensor network. When the sensor node management server 13 receives a request for a software update from a specific sensor node, the sensor node management server 14 sends the sensor node to the software management servers 14 to find a software management server that stores software corresponding to the corresponding sensor node. Information is transmitted to query the software management server storing the software corresponding to the corresponding sensor node. When the sensor node management server 13 receives a response from the at least one software management server 14 that the software corresponding to the sensor node is stored, the sensor node management server 13 is a gateway 11 or a management node managing the sensor node. The location information (for example, IP information or URL information) of the software management server 14 storing the software corresponding to the information is transmitted.

2 is a block diagram showing a schematic configuration of a sensor node 100 used in the present invention. In general, the sensor node 100 includes a wireless communication module 101, a controller 102, and a flash memory 103 as a nonvolatile memory. As the volatile memory, a RAM and a sensor 105 may be included.

The wireless communication module 101 is controlled by the controller 102 and is for wirelessly communicating with other sensor nodes or sink nodes or gateways or management nodes. The controller 102 transmits the sensing information sensed by the sensor 105 to another node through the wireless communication module 101, and in accordance with the control information transmitted through the wireless communication module 101, the wireless communication module 101. Or control the sensor 105. The controller 102 also stores a new version of software (such as a driver or application software) delivered through the wireless communication module 101 in the flash memory 103 to update or newly install the software of the sensor node. The software operated on the controller may be an application software (S / W) 106, middleware 107, an operating system (OS) 108, a driving driver. In this case, the driving driver plays a role of controlling input / output between other modules or peripheral sensor nodes according to input / output commands from the operating system, and may be more advantageous in consideration of expansion when the sensor node is separated from the operating system (OS).

3 is a flowchart illustrating a method for remotely managing sensor node software in a sensor network according to the present invention.

First, the sensor node developer must store the software (drive driver, middleware, application software, etc.) for the produced sensor node in at least one software management server among a plurality of software management servers distributed in a broadband integrated network (BcN). Should be placed.

In addition, the software update event of the sensor node may occur in the following cases.

First, if a newly developed sensor node is newly deployed and the sensor node is connected to the network but the required software for the sensor node is not installed, the gateway or management node updates the software to download the required software for the newly installed sensor node. Can raise an event.

Second, when the sensor nodes are already installed in the network, when a new version of the software is developed by the sensor node manufacturer, the software management server is a sensor node management server, and the new version of the software is stored and the information of the sensor node is displayed. The sensor node management server informs the gateway node or the managed node about the new version of the software, and informs the sensor node of the sensor node. Alternatively, the managed node may generate a software update event.

The gateway or management node that manages the information of the sensor nodes (manufacturer, product name, serial number, software version, etc.) updates the sensor node software by requesting a software download request from the sensor node 301 or a software version update notification from the sensor node management server. When the event occurs (303), the sensor node management server transmits the information of the sensor node (for example, a combination of a manufacturer, a product name, a serial number, and a software version selected). At this time, the gateway or the management node transmits the sensor node information to the sensor node management server together with its IP information (305).

When the sensor node management server receives sensor node information for software update of the sensor node from the gateway or the management node, the sensor node management server inquires whether distributed software management servers are storing software for the corresponding sensor node (307). The sensor node management server receives a response from the at least one software management server as to whether there is software for the corresponding sensor node (309). At this time, the software management server may respond to the sensor node management server with its location information (for example, its IP information or URL information) and flag information indicating whether the corresponding software exists. The software management server may further transmit version information of the software to the sensor node management server when the version information of the software installed in the corresponding sensor node is not transmitted from the sensor node management server.

The sensor node management server may select an optimal software management server based on the response transmitted from each software management server. That is, the sensor node management server is an optimal software management server for downloading software for the corresponding sensor node based on the information transmitted from each software management server (the existence of the corresponding software or the software version information or the processing load ratio of the server, etc.). Determine. When the optimal software management server is determined, the sensor node management server transmits the location information of the software management server that can download the corresponding software to the requested gateway or management node (311).

When the gateway or the management node transmits the information of the optimal software management server capable of downloading the corresponding software from the sensor node management server, the gateway or the management node forwards the information requesting the download of the software to the corresponding software management server (313). The download request information may include IP information of a gateway or a management node and software information required for download. Optionally, if necessary, the download request information may include information of a sensor node.

The software management server receives a download request of the corresponding software from the gateway or the management node, and downloads the corresponding software to the gateway or the management node (315).

When the gateway or the management node downloads the software from the software management server, the gateway or management node delivers the downloaded software to the sensor node (317). Accordingly, the newly installed sensor node is installed with the software necessary for operation. In addition, a new version of the software can be installed on the sensor node where the old version of the software was installed.

On the other hand, the method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention. The recording medium may include any type of computer readable recording medium.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
