| 摘 要： | 线型拓扑无线传感器网络的数据传输跳数多,传输路由单一,延时大,各节点转发的信息量不均衡.针对这些特点,分析了传统无线传感器网络协议在线型拓扑网络中存在的问题,提出链式快速分簇数据传输协议.该协议采用周期性地对传感器节点进行时间基准化,并且对数据进行逐段融合与回传.实际数据传输测试结果表明,链式快速分簇数据传输协议在传输延时、低功耗方面有优越的性能.

| Abstract: | Wireless sensor networks(WSN) with linear topology have special features such as a large number of hops,unique routing,long delay,and unbalanced information transmission from the nodes.From these features,this paper analyzes the problems of normal protocols used in linear sensor networks,and proposes a fast data transmission protocol based on chain cluster.This protocol applies a reference time on the nodes periodically and transmits fused data to the sink node.Experimental results show that the proposed pr... |
