一种基于非均匀分簇的大规模无线传感器网络路由协议

An Uneven Cluster-based Routing Protocol for Large Scale Wireless Sensor Networks

提出了一种适合于大规模无线传感器网络的非均匀分簇路由协议UCRPLS,其主要思想是:借鉴理想情况下最优跳数和能量消耗最小的定理,将网络划分为大小不等的区域(簇),簇首采用多跳方式将数据传递给基站,越靠近基站的簇规模较小,便于簇首为簇间的数据转发预留能量。该协议突破了网络规模的限制,均衡了簇首负载。仿真结果显示,本协议能更好地延长网络的生存周期。

In this paper, an uneven cluster-based routing protocol, UCRPLS（An Uneven Cluster-Based Routing Protocol for Large Scale Wireless Sensor Networks） is proposed for large scale wireless sensor networks. The main idea is dividing network into different sizes of areas（clusters） according the theorems of optimal number of hops and the minimum energy consumption in ideal conditions. The cluster heads use multi-hop mode of communication to send their data to the base station. The clusters closer to the base station have smaller sizes than those farther away, thus the cluster heads closer to the base station can preserve some energy for data forwarding. The protocol broke the network seale limit and balanced the energy load of the cluster heads. Simulation shows that it prolongs the lifetime of the network.
