针对无线传感器网络最小跳数路由协议数据包多路径冗余传输,能量消耗不均衡等问题,提出了一种改进的无线传感器网络最小跳数路由协议。该协议通过引入侦听机制在网络中建立传输路径,同时采用一种新的能量均衡策略解决关键节点能耗过快的问题,以有效延长网络寿命。通过自主研发的无线传感器网络仿真平台进行仿真,比较最小跳数路由协议和改进协议的性能。实验结果表明:改进协议能够很好的均衡网络能量消耗,提高网络能量有效性,延长了网络寿命。

Aiming at problems of too much redundant data and non-balanced energy consumption in minimum hop routing protocol, an improved minimum hop routing protocol for wireless sensor networks is proposed. Snooping mechanism is introduced into the protocol in order to establish the transmission path in the network. In addition, a newly energy balancing strategy is adopted to deal with the excessive energy consumption in key nodes so that the lifetime of the sensor networks can be prolonged. Wireless sensor networks simulation platform based on independent research and development is used to simulate, the minimum hop routing protocol and the performance of the improved protocol is compared. Experimental results indicate that improved protocol attributes to balance network energy consumption to a large extent, improve network energy efficiency and extending the network lifetime.
