Abstract:

In order to effectively use the heterogeneity of node energy and reduce the network energy consumption and prolong network stable period, a clustering routing algorithm for heterogeneous sensor networks with multistage energies was proposed, takeing into account the residual energy of nodes and the distance from nodes to the base station synchronously.The residual energy of cluster heads and the energy consumption of communication between the nodes and the base station were considered comprehensively to select the appropriate nexthop route node. Simulation results show that this algorithm can balance network energy consumption efficiently and extend network stability period.This routing algorithm has a better performance than some ordinary algorithms in the indexes of maintaining the number of survival nodes, reducing the network energy consumption and increasing the throughput of data transmission of nodes. It indicates that it can get better computational results when the factors of energy and distance are considered comprehensively rather than only considering one factor: energy or distance.
