基于Floyd的无线传感器网络簇内能量优化

Wireless sensor network energy optimization in cluster based on Floyd

无线传感器网络中的能量空洞是无法避免的,能量空洞问题会加速整个网络生命的死亡。针对簇型网络中容易出现能量空洞问题,提出一种新的基于能量效率的簇中路由算法(a Route Algorithm based Energy Optimization in Cluster,RAEOC)。网络被划分成多个等区域的簇类,RAEOC将Floyd算法应用到簇内节点路由机制中,使节点传输数据到汇聚节点的使用能量最优化,并且平衡整个网络的能量消耗。仿真结果表明,RAEOC算法比传统的分簇算法如LEACH和PEGASIS可分别节省68%和54%的能量。

Suffering from energy hole problem is inevitable in the wireless sensor networks.Energy hole problem will hasten the death of the whole network.To solve this problem in the clustering network,we propose a route algorithm based energy optimization in cluster（RAEOC）.The network is divided into some uniform clusters,and RAEOC applies the Floyd algorithm to intra-cluster routing.It optimizes the energy consume of data transmission from sensor nodes to sink,and balances the energy consume of the whole network.Simulation results indicate that RAEOC algorithm can save energy 68% and 54% than traditional clustering algorithms such as LEACH and PEGASIS.
