基于负载均衡评价模型的无线传感器网络拓扑控制算法
Topology control algorithm based on load balancing evaluation model in wireless sensor networks
摘要
Abstract
In wireless sensor network, due to the nodes' unbalanced load, the low energy nodes may die prematurely. It will lead network partition or collapse and the network lifetime will be shorten. So it is unpractical with the unbalanced load network. Accord-ing to the impact factor of the node's residual energy, the transmission power and the load, the load balancing evaluation model ( LBEM) is built to realize the load balancing topology in this paper. And considering the larger information complexity of centraliza-tion algorithm, a distributed topology control algorithm is presented based on the load balancing evaluation model. Then its stability is proved applying to the lyapunov's direct method. The simulation results show LBEM can balance the energy consumption and improve the network practicability.关键词
