Routing Algorithm Researches Based On Pirce Mechanism In Multi-domain Wireless Sensor Networks

Wireless Sensor Network, as one of the high-tech industries in the future science, hasshown significant application in the field of military, agriculture, smart home, and so on,which will support the power for the economic development, social advance, human lifeimprovement. No matter domestic or foreign, every country invested enormous human andmaterial resource to research the wireless sensor network, even let it rise to the nationaldevelopment strategy, just because they all think wireless sensor network is the method to getrid of the global economic decline, and also the pillar industry of future. The research ofwireless sensor network is underway, which contains the directions of the extension ofnetwork lifetime, the utilization of network energy, the topology of network, etc.Multi-domain wireless sensor network is one branch of the traditional wireless sensornetwork, and also one direction of the future development. Multi-domain wireless sensornetworks are a set of large scale sensor networks which are deployed in the same physicallocation, but controlled by different authorities. The different networks can cooperate withothers, i.e. utilize other networks to route data and transmit information. In the multi-domainwireless networks, not only exists the issues of wireless sensor networks, such as the limitedenergy of node, lack of storage capacity, and the limited computing resource, but also havethe problems among the multi-domain networks, for example, the cooperation between thenetworks, the trust issue among different network. So when we design the route algorithm ofthe multi-domain wireless sensor networks, the above issues should be considered carefully.This paper is within the framework of multi-domain wireless sensor networks. Ourresearch is mainly divided into two modules: the network model construction and the designof the route algorithm.In the stage of network model construction, we propose one new topology controlstrategy, combined the Critical transmitting range (CTR) and K-Neigh topology controlstrategy. This improved topology control strategy can correspond with the deployment inpractice, but also make the topology more reasonable. Then we utilize it to construct ourmulti-domain wireless sensor network model. In the model, we set up two work modes: one isthe Network Cooperation (NC) mode; the other is Network Standalone (NS) mode, whichused for the compare between the multi-domain wireless sensor network and the twoindependent wireless sensor networks.Later, in the design of the network route algorithm, we propose the new algorithmBiPEL, which use the credit incentive. Inside the single networks, the node price is made by the location and remaining energy of node; when crossing the networks, the base price basedon every single network is studied. And also we extract one simple LER algorithm, as thecomparison algorithm in the simulation experiment.The results show the BiPEL algorithm improves the network lifetime and the balance ofnetwork energy more efficiently. The BiPEL algorithm is more fit to the scenario ofmulti-domain wireless sensor network, and we can take advantage of the BiPEL algorithm toresearch the network characteristics.
