一种能量高效的无线传感器网络拓扑控制算法

通过对现有拓扑控制算法的研究,针对无线传感器网络中节点能耗分布不均匀的问题,提出了一种能量高效的拓扑控制算法(EETCA)。该算法以均衡全局能耗为目标,综合考虑了节点的剩余能量、簇的规模、数据最优传输跳数等因素,避免了部分节点能量消耗过快,从而有效地均衡网络负载。仿真结果表明:EETCA在能耗均衡方面均优于原来的算法,延长了无线传感器网络的生命周期。

An energy efficient topology control algorithm for wireless sensor networks

Through research on current topology control algorithms,aiming at energy consumption distribution uneven problem of WSNs node,propose an energy efficient topology control algorithm（EETCA） for wireless sensor networks（WSNs）.The algorithm can avoid partial nodes energy dissipation too fast and balance load of network effectively by taking residual energy of nodes,the size of cluster and the optimal transmission hop count of datas into account.Simulation results show that EETCA is prior to the original algorithm in energy consumption balance and prolong the lifecycle of WSNs.
