摘　　要：提出了一种新的能量有效的非均匀分簇路由协议—UCRP.根据距离基站的远近将网络分为大小不同的簇;簇内数据传输根据簇范围的大小采用单跳或多跳;簇间数据传输构建多跳路由,簇首选择下一跳节点时将能量与最小跳数路由算法相结合;最后在能量有效的前提下对LEACH协议易受到HELLO flooding攻击提出了安全设想.仿真结果表明:该协议能够有效地均衡簇首和全网能耗,延长网络生存时间.The paper design a new energy efficient uneven clustering routing protocols-UCRP.Dividing the network into some clusters of different size according to the distance from base station;the protocol transmits data using one-hop or multi-hop at intra-cluster;and constructs the multi-hop routing among inter-clusters,the cluster head select it′s next hop node combining the energy of node with the minimum-hop routing algorithm;finally,under the premise of the energy efficient the paper put forward security idea based on the LEACH protocol is easily attacked by HELLO flooding.Simulation results show that the routing protocol effectively balances the energy consumption of cluster heads and the whole network,prolongs the network lifetime.
