Abstract:To solve the problems of uneven energy consumption, prone to "hot zone" etc. in long distance band-type wireless sensor network, a energy-efficient routing protocol for long distance band-type network ( ERPLDB ) is presented in this paper. In ERPLDB, average energy consumption of each cluster in the network is calculated according to the energy consumption formula of the network energy consumption model. And the network is uneven clustered by equaling average energy consumption of each cluster. Then more close to the sink node, smaller the scale of the cluster. So the cluster more close to the sink node can save more energy to forward data coming from the more distance cluster. And the "hot zone" problem is solved effectively. Simulation results show that ERPLDB can balance the long distance band-type network energy consumption, effectively extending the life of network.
