摘要 针对LEACH协议生成非均匀的簇造成能量损耗的问题,提出一个基于节点剩余能量和地理位置,用于分层次均匀成簇和建立备用簇头以减少反复成簇频率的路由协议LEACH-EP。仿真实验证明,该协议在节点初始能量和网络规模相同的条件下,消耗的能量要远少于LEACH协议,节点生存时间更长,更适用于大规模无线传感器网络的低能耗路由协议。 Aiming at the problem of energy loss result from non-uniform cluster generated by LEACH protocol,a routing protocol,LEACH-EP,is proposed,which is based on the node’s remaining energy and the geographical position,for hierarchical symmetrical clustering in administrative levels and the establishment of the spare cluster to reduce the frequency of repeated clustering.The simulation results show that under the same conditions of initial energy in the nodes and network size,the energy consumption is far less than the LEACH protocol,and the nodes survive longer,more suitable for large-scale low-power wireless sensor networks routing protocols.
