Abstract: Limited energy and easy invalidation are the characteristics of WSNs (Wireless Sensor Networks). To prolong the lifetime of WSNs for building monitoring, an algorithm named CFDGSBRWB is proposed, which is a Cooperation Forwarding Data Gathering Strategy Based on Random Walk Backup in Wireless Sensor Networks. The algorithm consists of data backup based on random walk and cooperation forwarding data gathering by WBA (Wireless Broadcast Advantage). Simulation results show that CFDGSBRWB can reduce packet lost ratio and enhance fault-tolerance significantly under the condition of the insignificant increase of communication traffic, and is suitable for large-scale wireless sensor networks.

Keywords: WSNs; cooperation forwarding; data gathering; wireless sensor networks; random walk; WBA; wireless broadcast advantage; simulation; packet lost ratio; fault tolerance; network lifetime; building monitoring.
