Abstract
The invention discloses a medium access control method for prolonging network lifetime in a wireless body area network, which mainly solves the problem that network topology lacks the self-adaptive adjustment capability based on the current residual energy of a node in the existing research on the medium access control of the wireless body area network. The method is implemented by the steps as follows: under a normal communication state, a node immediately requests a relay towards a network coordinating point when detecting the current residual energy is lower than an energy threshold value; the network coordinating point selects the relay for the relay request node in the whole network through a relay selection superframe structure; the network topology is changed from a star structure into a tree structure; and a medium access control layer adjusts a next-hop superframe structure in accordance with the topology. Compared with the existing method for prolonging network lifetime in a wireless body area network, the invention can realize the self-adaptive adjustment of the network topology without increasing additional relay nodes, thereby prolonging the network lifetime of the whole wireless body area network.
Description
Technical field
The invention belongs to communication technical field, relate to media access control method, a kind of media access control method for wireless body area network specifically, the method is guaranteeing that grouping successfully accesses under the prerequisite of channel, extends network lifetime to greatest extent.
Background technology
Wireless body area network (WBAN, Wireless Body Area Network) is a kind of centered by human body, by be distributed on the person, on clothing, even each node of body interior and the cordless communication network that personal terminal forms.In the wireless near field communication field, although there is Wireless Personal Network WPAN technology, but this concept of body area network has further expanded to the short distance wireless communication technology the communication between the various kinds of sensors that is deployed on human body and in human body, so its transmission range is shorter.WBAN is of wide application, from remote medical monitoring, calculate mutual to human body, there is application potential the aspects such as education and amusement, particularly can be around the human body due to WBAN or body surface even work in body, it can be not affecting in people's normal life situation the domestic medicine monitoring hommization more that becomes, and is also more convenient.
In wireless body area network, the energy content of battery of sensor node is limited, therefore how efficiently to utilize energy with the operating time of prolongation sensor node, and then makes the life span of whole network improve, and becomes the primary goal in the wireless body area network design.Many scholars had done a lot of work at the energy efficient of wireless body area network aspect utilizing in recent years, had extended to a certain extent the life span of network.
G.Fang and E.Dutkiewicz, BodyMAC:Energy efficient TDMA-based MAC protocol for wireless body area networks, In Proc.of 20099th International Symposium on Communications and Information Technologies (ISCIT 2009), Incheon, South Korea, pp.1455-1459 proposes a kind of media access control MAC protocol based on time division multiple access TDMA.Concrete grammar is: it is periodic TDMA superframe with channel distribution, and each TDMA superframe is divided into again descending sub frame and sub-frame of uplink two parts.Descending sub frame is used for the focal point to the service interaction of terminal node, and sub-frame of uplink is used for terminal node and sends data to the focal point.In order to allow as much as possible node be in the utilance of resting state and raising channel, sub-frame of uplink is further divided into again competition phase CAP and non-competing phase CFP.Wherein, CAP only is used for transmitting little MAC grouping, and CFP is according to traditional TDMA form work.This method simply and has effectively been saved the energy of sensor node, but considers human body transmission environment and network characteristic that WBAN is special, and still there is the deficiency of following two aspects in the method:
1, the method has been ignored the business diversity of WBAN, and for example, the multiple business such as electroencephalogram (EEG) EEG, electrocardiogram ECG and body temperature, blood pressure is also deposited.Different business has different business arrival rate and data rate requirement in actual applications.The difference of business arrival rate and data rate will inevitably cause different nodes to produce huge difference to the depletion rate of energy, if these different application are not added differentiation, all distribute identical tdma slot in the CFP of TDMA superframe, will inevitably cause the high node energy premature depletion of business arrival rate and data rate, and the time slot most of the time of the few node of traffic carrying capacity be in idle condition, finally cause the reduction of the inhomogeneous and whole network lifetime of the energy expenditure rate of nodes.Therefore should consider based on the energy consumption of each node in the Protocol Design of wireless body area network.Particularly media access control MAC protocol design, for extending as much as possible each node life span, the energy consumption of the different nodes of reply gives difference and treats.
2, the wireless device in WBAN is applied to around human body, and the path loss around human body is than large many of the loss in the free-space propagation situation, especially when the link of communicating pair is non line of sight NLOS, such as, transmitting terminal is positioned at the back of human body and receiving terminal is placed on people's shirtfront, even very large these the internodal direct communications of transmitting power are also not necessarily feasible.Therefore, in order to set up reliable link between node, should consider also in the Protocol Design of wireless body area network that multi-hop connects.
So A.Ehyaie, M.Hashemi and P.Khadivi, Using relay network to increase lifetime in wireless body area sensor networks, In Proc.of the 10th IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks ﹠amp; Workshops (WoWMoM), Kos, Greece, June 2009, and pp.1-6 proposes to introduce extra via node to help the terminal node forwarding data to divide into groups to destination node before the WBAN netinit.The number of via node is determined by the path loss factor plus original node of human body and the distance between destination node.By the forwarding of packets effect of via node, the life span that obvious the method has effectively improved the energy expenditure rate of sensor node and then extended network.But the method is not considered the network cost problem of bringing because extra via node is installed, and in network, all nodes have the interior neighbor node of a sighting distance LOS scope but the number of suppose relay node can increase always.Therefore the method and the wireless body area network that is not suitable for the actual node Limited Number use.What the method mainly solved in addition is the routing issue of WBAN, does not relate to the problem how the MAC layer is realized.
The International standardization aspect, in order to accelerate the progress of WBAN, in November, 2007, IEEE 802.15 working groups have formally set up the 6th task groups TG6, are devoted to the physical layer of WBAN and the standardization effort of media access control layer.This standard still is in the formulation stage at present.Extend network lifetime and be one of most important performance index that IEEE 802.15.6 standard need to realize.In the existing international standard of having announced, IEEE 802.15.4 is because agreement is simple and be widely used in existing short range communication systems, and be near a world standard as low-power consumption low rate wireless near field communication of WBAN designing requirement, therefore can be used as a kind of alternative that wireless body area network is realized technology.IEEE 802.15.4MAC layer can be supported Star network and two kinds of topological structures of peer-to-peer network, but, in the IEEE802.15.4 standard, most content is all the working specification about Star network, limited about the content in the course of work standard of peer-to-peer network, for example: about the multi-hop superframe structure that uses under peer-to-peer network, the Media Access Control management entity MLME that only mentions common focal point in IEEE 802.15.4 standard will guarantee that the superframe outgoing superframe that sends each common focal point will complete within the inactive phase of superframe incoming superframe that it is received, how the outgoingsuperframe that standard does not relate to each common focal point when having a plurality of common focal point simultaneously in the same sublayer of peer-to-peer network avoids the problem of colliding.In addition, owing to exceeding critical field, the MAC problem of co-ordination how when not relating to network in standard and switching between two kinds of different topology structures.

Embodiment
Suppose under normal communication state, adopt the superframe structure communication based on IEEE 802.15.4 star topology between all nodes and network coordination point, the structure of this superframe as shown in Figure 1; And suppose that in network, whole nodes all can be measured the residual energy value of oneself in real time, if certain node i is found the residual energy value E that its is measured
iEnergy threshold value E lower than the network regulation
t, this node begins to claim in the present invention that to network coordination point request relaying this node is the relay request node.
With reference to Fig. 2, the present invention includes relay request, relay selection and superframe and adjust three parts, concrete steps are as follows:
One, relay request
Step 1: relay request node request relaying
If just in time there be the frame mutual with network coordination point in the relay request node, this node is asked relaying by mutual frame control domain as shown in Figure 3 to network coordination point, representing that node has relay request when the 7th reserved place of frame control domain is 1, is 0 non-relay request.Do not have and the mutual frame of network coordination point if the relay request node is current, it sends a special relay request frame to network coordination point, as shown in Figure 4, this relay request frame is still asked relaying with the 7th reserved place of its frame control domain to network coordination point, and the media access control layer load is empty.
Step 2: network coordination point is received the node reply acknowledgement frame of the backward transmission relay request of relay request, is used for confirming to receive.
Two, relay selection
The superframe structure that relay selection process of the present invention is used as shown in Figure 5, it is the improvement to IEEE 802.15.4 star topology superframe structure, be that network coordination point is according to the relay request situation in last superframe, increase relaying at the beacon frame of next superframe with between the competition phase and seek phase and trunking decision phase two parts, being used for network coordination point is the relay request node at the whole network.Begin at the relay selection superframe, network coordination point structure beacon frame, its frame structure as shown in Figure 6, this beacon frame is the improvement on the basis of beacon frame structure in IEEE 802.15.4, namely increased wait relay address list territory relay pending address list in the media access control layer load, be used for notice relay request node and seek the time slot allocation information of phase at relaying; Afterwards, the network coordination this beacon frame of naming a person for a particular job sends with broadcast mode, and after all nodes received beacon frame, the superframe length, the relaying that read were wherein sought phase length, trunking decision phase length and competition phase length parameter, and are recorded in local cache.
After network coordination point sends beacon frame, the relaying that network coordination point and all nodes enter is as shown in Figure 5 sought the phase, and to be network coordination point wait for that according to beacon frame number and the order of contained address in relay address list territory distribute to corresponding relay request node successively to each time slot in this period.Each relay request node is sought the Minimum Power Level l broadcast relay that can provide with its chip in the phase time slot at relaying and is sought frame, its frame structure as shown in Figure 7, this relaying searching frame is the expansion to IEEE 802.15.4 frame structure, its media access control layer load is empty, is used for the relay request node and seeks its l level neighbor node of phase time slot searching at corresponding relaying.Other nodes in network are opened the transceiver of self and are intercepted relaying searching frame.If certain node device type that listens to relaying searching frame is full-function device, this node is called the l level neighbor node of relay request node, if node is sought the phase at relaying and is not listened to relaying and seek frame or listen to relaying that to seek the node device type of frame be to simplify function device RFD, this node is closed the transceiver of oneself, in the dormancy of ensuing trunking decision phase.
After the relaying searching phase finished, network coordination point, relay request node and l level neighbor node entered the trunking decision phase as shown in Figure 5, and other nodes are in this section dormancy in the time.Network coordination point is in notification frame of first time slot broadcast transmission of trunking decision phase, its frame structure as shown in Figure 8, this notification frame is the expansion to IEEE 802.15.4 frame structure, its media access control layer load is the address list of all full-function device FFD in network, be FFDaddress list, be used for notice l level neighbor node and send in the trunking decision phase time slot allocation information that relaying is replied frame.All l level neighbor nodes receive this notification frame and therefrom extract own address sequence information in network, according to the address sequence information of obtaining, each l level neighbor node sends relaying to network coordination point without collision successively and replys frame in the corresponding time slot of trunking decision phase, its frame structure as shown in Figure 9, this relaying reply frame is the expansion to IEEE 802.15.4 frame structure, its media access control layer load comprises the current remaining value of l level neighbor node and the relay request node address information that it listens to, i.e. E
iWith Heard address list, be used for network coordination point and obtain the l level neighbor node dump energy information of each relay request node, and make trunking decision.
Network coordination point passes through broadcast relay decision-making frame at last time slot of trunking decision phase, its frame structure as shown in figure 10, this trunking decision frame is the expansion to IEEE 802.15.4 frame structure, its media access control layer comprises the relay node address list information of the node address list of successfully choosing relaying and its correspondence, be successful relay request node address list and Corresponding relay node address list, be used for the result of notice relay request node and l level neighbor node network coordination point relay selection.Relay request node and l level neighbor node receive this trunking decision frame, if the relay request address of node is included in the relay request success node address list of trunking decision frame, its request relaying success, otherwise mean that the relay request node is with the failure of l level power level request relaying.The later course of work of the node of relay request failure is divided into following two kinds of situations: the first, if the power level progression l when relay request failure node broadcast relay in step 4 is sought the power level progression l of frame and surpassed it and the direct communication of network coordination point
1, after this node is l+1 with l assignment again, change step 1 over to; The second, if the value of the power level progression l of relay request failure node increases to l
1-1 o'clock, network coordination point was not yet for it successfully chooses relaying, and this relay request node is abandoned relay request and directly communicated by letter with network coordination point.
Mutual for guaranteeing that the relay selection process does not affect in network the regular traffic of each node and network coordination point, the trunking decision after date, although network coordination point is chosen relaying for the relay request node, but at this moment network schemer does not adjust immediately, be that each node is still directly communicated by letter with network coordination point, have the mutual node of service needed and network coordination point the residue active period of relay selection superframe part and network coordination point finishing service alternately, in inactive phase part, all nodes and network coordination point enter resting state.
After whole relay selection superframe finishes, in order to save the dump energy of relay request success node, the hub-and-spoke configuration of network topology structure during by proper communication is adjusted into tree structure, to be network topology structure prop up the route single-hop at relay request success node becomes multi-hop, later in process, relay request success node only need use l level power level to communicate by letter with the via node of its correspondence to get final product, no longer direct communication between the successful node of network coordination point and relay request.
