摘要
针对现有WSN分簇路由算法的不足均衡网络能量消耗,引入一种新的基于竞争机制的无线传感器网络分簇路由协议,利用"屏蔽效应"控制簇头在簇中的分布和各簇成员节点数目,同时采用独立的簇头选举制度按轮仅在簇内广播簇头信息来减少簇头选举次数从而进一步节省能量。并采用基于阈值的单跳与多跳相结合的簇间通信方式。当与现有协议比较结果表明,新算法有效解决簇头分布不均的问题,能更好的均衡节点能量负载,其能量有效性也得到了很大的提高,延长了网络寿命。
Abstract： According to the shortages of existing cluster routing protocols of WSN, we proposes a routing protocol which based on the network energy consumption to balance the energy consumption by using ＂Shielding effect＂ to control the distribution and the number of clus- ter heads. We adopt independent cluster head electoral system and just broadcast the cluster head information in the inner cluster to save en- ergy. Use the combination of single and multiple hops which based on the value to communicate among clusters. When compared with the ex- isting agreement the results indicate that the algorithm can effectively solve the problem of uneven distribution of cluster head and the net- work load is more balanced. Moreover, the energy--efficiency of the network has been improved greatly and prolonging the network life.
