一种改进的簇头成链路由协议

摘要

针对LEACH路由协议和PEGASIS路由协议的局限性,提出一种改进的簇头成链路由协议.将网络内所有传感器节点以区域为单位集合成簇,由Sink节点向下遍历区域内全部节点形成多条簇头链,通过计算数据丢包率得到能串联整个网络的簇头链.仿真结果表明,该路由协议具有较好的数据传输可靠性和实时性.%According to the limitations of LEACH and PEGASIS, an unproved cluster head chaining routing protocol is proposed. The core idea is all of sensor nodes in the network are divided by area, sink goes down through all the nodes within the region to establish a number of cluster head chaining. By calculating the packet loss rate, a final cluster-head-chain which is able to concatenate the whole network is reached. Simulation result shows that the improved routing protocol has good reliability and real-time of data transmission.
