Research Based On Energy Balance Routing Protocol For Wireless Sensor

With the rapid development of wireless communications, sensor field,microprocessors and embedded computer field. Today, a large number of sensor nodes canbe made in the absence of human intervention, by pre-programming, according to certainrules, their own wireless sensor network consisting of various topologies emerged(Wireless Sensor Network, WSN). For wireless sensor network energy balancing and datatransmission reliability of these two issues, mainly to study the routing algorithmimplementation and simulation experiments, the study of these two aspects as follows:(1) For a single tree network node failure will directly affect the communicationbetween the nodes of their son, thereby affecting the problem network coverage area. Wedesigned a mesh topology based on tree topology. Past, wireless sensor network nodes willbe to determine the address and location in the network based on the factors of the order ofthe current node to join the network, link quality, communication radius, so as to form atree network, we passed on the basis of tree network the depth of the pre-defined networknode, i.e., to determine the depth of the node in the network when the node is initialized,and by broadcasting a route request packet to make the mutual connections between thenodes in the same depth to form a mesh network.(2) After the formation for the mesh network node in the network broadcast routingrequest packet, causing a routing request packet in the network flooding problems. Wedesigned a routing request packet processing, network formation stage, first establishedbefore the process of routing nodes that transmit data will parse out the address of thedestination node address and the source node and then by determining the network node todetermine the depth of their own the general direction of the route request packettransmission, the route search can establish communications paths.(3) This design algorithm for node reliability model, considering the factors that linkquality, residual energy, such as selecting the optimal cost routing path for communication.In the network session, according to the calculation method to determine the energy levelsof the node energy into sufficient energy, low energy and energy alert three levels, and the energy level of the threshold value of the total energy decreasing as the network changes,so it can from individual nodes and the whole network energy balance two considerationsproblem, the maximum extension of the network life cycle.(4) In order to more clearly illustrate the idea of routing protocol designed in thispaper, the use of simulation platform to build the model. The feasibility of usingMATLAB software programming, routing protocols experimental tests, comparativeanalysis and performance evaluation, the proposed verification protocol.
