摘要
路由协议设计是无线传感器网络的一个重要研究领域,可靠性、低开销和易于维护是无线传感器网络路由协议的设计目标,其中基于跳数的路由协议以其简易、有效的设计思路,一直以来得到广泛关注。在详细分析基于跳数的无线传感器路由协议发展现状的前提下,对最小跳数路由算法的组网和数据传播阶段加以改进。通过在OMNeT++仿真环境中与原始最小跳数协议、定向扩散协议的比较,验证了改进后的算法在可靠性、负载均衡、延长网络生命周期和低路由开销方面的优势。
Routing protocol design is an important research area in wireless sensor networks,and reliability,low-cost and easy to maintain are goals of WSN routing protocol design.Hop based routing protocol has been receiving extensive attention for its simple and effective design ideas.This paper analyzed hop based routing protocol in detail analysis,and then proposed an improved routing policy.Compared with MHC and DD in OMNeT＋＋ simulation tool,the improved policy proves its strength in reliability,load balancing,extending network lifetime and low routing overhead.
