摘要： 在栅格状分簇路由协议(GROUP)中，存在簇头分布不均匀、主汇聚节点选择不明确、数据传输不沿着最佳路径传输等缺点。为此，设计一种基于距离比较趋零法的栅格分簇无线传感器网络路由协议。采用能量优先的簇头轮换机制，实现数据的可靠传输和簇内节点功耗的均匀分布，并完成对GROUP协议和改进的栅格分簇路由协议的仿真。综合对比分析结果表明，该协议在复杂度、构造栅格分簇的能量开销和路由延时方面明显优于GROUP协议，并且在大规模节点的情况下性能更优。

Abstract: In the GROUP protocol, the cluster heads’ distribution is irregular and the data path is not the best, so it is necessary to design a better routing protocol. Based on the distance comparison becoming zero method, a grid clustering routing protocol is designed, which chooses the most appropriate neighbor cluster header to carry on the data transmission to guarantee stable data transmission and balanced distribution of energy cost of node inside the cluster, and simulation comparison is completed between GROUP agreement and the improved grid clustering routing protocol. Synthetical comparison and analysis results show that the proposed protocol has obvious ascendant in the complexity, the energy cost of constructing grid clustering and routing delay, especially when the network has many nodes.
