For railways, bridges, highways and others constructed by fixed-chain type linear wireless sensor networks, many studies have focused on routing protocol research with stetted communication radius.However, different communication radius directly impacts the transmission; thereby affects the performance of the network lifetime and protocols.To solve this problem, this paper models the impact of changes in the communication radius on network performance.First, the lifetime and latency model of double-chain linear topology network are proposed, the effect process of changes in the communication radius on the network life, network delay is detailed analyzed, and then optimal communication radius algorithm is put forward based on delay tolerance.Further analysis is concerned on the effect of different network widths, length and scale to the optimal communication radius.Configuration scheme of communication radius is proposed under different network structures in order to maximize network lifetime as the optimization target.Finally the effectiveness of the proposed model and scheme are verified by theoretical and simulation analysis.It is meaningful for configure reasonable communication radius at different real project.
