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:

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 protocol possesses low delay and low power consumption.

Key words: linear topological structure; wireless sensor networks; data fusion; time synchronization
