We propose an energy-efficient communication protocol, called optical- LEACH (O-LEACH), for hybrid sensor networks that consist of distributed optical fiber sensor links located at the center and two isolated wireless sensor networks (WSNs) with randomly scattered nodes. Network performances in terms of lifetime are simulated with ~30% improvement over LEACH protocol.
