Wireless sensor network is a kind of emerging, extremely potential network technology, this network can by a large amount of simple nodes greatly redundantly random placement in certain area, between node by the networking of self-organizing ground, various complex environments in Real-Time Monitoring, perception and collection network distributed areas or the information of monitoring target collaboratively, and these information are netted to interior processing, thereby obtain detailed and information send backstage backbone network server or dependent observation person to accurately.
In radio sensing network application, sensing node networks and need to obtain gateway or telegon license distribution network address.Generally speaking, the coverage of mesh network is far longer than other topological structure networks, therefore, and along with the expansion of network size, when network edge place, to have node to add fashionable, access request message need to arrive gateway or telegon through multi-hop, by consuming a large amount of energy and channel resource, has increased network conflict probability like this, end-to-end access delay is corresponding increase also, in the middle of causing, the too fast consumption of routing node energy, affects network lifecycle, and network performance is declined.
Conventionally, cancellated radio sensing network coverage is all relatively large, and is concentrated as the sensing node distribution 16Wei network address by gateway/telegon.When networking apart from node relatively far away with gateway, need to send access request to gateway, gateway determines whether receive adding and distribution network address of new node.Access request signaling arrives gateway by the route of multi-hop, and this just makes the time delay of access procedure increase, and by consuming more signalling energy, has accelerated the energy consumption of middle routing node, affects the life cycle of network.
The general step of traditional algorithm comprises:
1. when having the sensing node newly adding to network, broadcast access request.
2. receive that all routing nodes of access request or gateway will reply territory net (PAN, Personal Area Network) address and a LQI value.
3. the routing node of relaying is selected optimum next-hop node and sends access request according to LQI value.
4. next-hop node sends to gateway according to routing table by access request.
5. if net interior nodes quantity surpasses threshold value, gateway will send refusal reply, otherwise gateway is replied transmission reception and distributed the 16Wei network address.
Wherein, wireless mesh sensing network is comprised of a large amount of static nodes that are dispersed in certain geographic area, by gateway, initiate initial networking, sensing node is according to link-quality (LQI, Link Quality Indication) with Ad hoc mode, select an optimum routed path, through multi-hop transmission, network request to remote gateways node.Generally, these nodes possess similar energy, storage, calculating and transmittability, and node is isomorphism, and its data flow multilist reveals the feature of " many-one ".
