Abstract:

For many-to-one wireless sensor network routing features and the LEACH protocol to establish the stage of information exchange characteristics, an improved routing algorithm based on the distance vector was proposed. The proposed algorithm could initialize the routing table no longer from the neighbors and did not need to build the routing path between any two points of the network. In the establishment phase of the cluster, each cluster could obtain the first cluster head information by the cluster head information broadcast, which could be used to simplify the protocol, and thereby reduce the agreement to achieve the required energy consumption in the J-sim simulation platform to achieve the above-mentioned system algorithm and its simulation study. Simulation results showed that the improved routing algorithm could significantly prolong the network life cycle, and the death of nodes was more evenly distributed. Considering the circuit loss, the CUP loss and state transitions and other aspects of energy consumption, this algorithm could also improve wireless sensor network performance, and extend the potential of the network lifecycle.
