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.
