大规模无线传感器网络中基于P2P的路由模型研究

摘要

Because P2P network and WSN have many similar features, the study of WSN routing based on P2P technology has become a new hot,but mainly research is suitable for small or medium WSN,and has unbalanced energy consumption and inefficient problem. This paper presented large-scale WSN routing model based on P2P. It combines LEACH protocol with structured p2p algorithm to make cluster header correspond with the base station by multiplehop method, improves WSN's scalability. At the same time, it expands smallest energy consumption path selection mechanism into WSN,supports node of the equilibrium of energy consumption. The experiment proves that this new routing model can greatly increase the large-scale WSN routing efficiency and life cycle.%P2P网络与无线传感器网络存在许多相似特性,目前基于P2P的无线传感器网络路由逐渐成为一个新的研究热点,但其研究成果主要适用于中小规模的网络环境,普遍存在网络能耗不均衡和效率低等问题.提出基于P2P的大规模无线传感器网络路由模型.通过在LEACH协议上融合结构化P2P算法使簇首节点以多跳的方式与基站通信,来提高无线传感器网络可扩展性,同时引入最小能耗路径选择机制,保障节点能耗的均衡.仿真实验证明,新模型有效提高了大规模无线传感器网络路由的效率和生命周期.
