Abstract :
Based on the protocol-low-energy adaptive clustering hierarchy (LEACH), we investigate an improved energy-efficient communication protocol for wireless sensor networks (WSNs) in the presence of distributed optical fiber sensor (DFS) links located at the center of WSN fields. Network performances in terms of lifetime of nodes are simulated for the cases that two WSNs can or cannot communicate with each other. The lifetime of the such sensor network with rectangular topology is further investigated.
