ECS: Efficient Communication Scheduling for Underwater Sensor Networks

Blog Article

TDMA protocols have attracted a lot of attention for underwater acoustic sensor networks (UWSNs), because of the unique characteristics of acoustic signal propagation such as great energy consumption in transmission, long propagation delay and long communication range.Previous TDMA protocols all allocated transmission time shoprider streamer parts to nodes based on discrete time slots.This paper proposes an efficient continuous time scheduling TDMA protocol (ECS) for UWSNs, including the continuous time based catherine lansfield ombre rainbow clouds eyelet curtains and sender oriented conflict analysis model, the transmission moment allocation algorithm and the distributed topology maintenance algorithm.Simulation results confirm that ECS improves network throughput by 20% on average, compared to existing MAC protocols.
