Distributed Scheduling and Routing in Underwater Wireless Networks
Several underwater network characteristics, including long propagation delays and a bandwidth dependent on distance, provide unique challenges to protocol designers. This paper presents STUMP-WR, a distributed routing and channel scheduling protocol, designed for heavily loaded underwater networks. STUMP-WR selects and schedules links using a distributed algorithm to overlap communications by leveraging the long propagation delays. Through simulation the authors show that STUMP-WR outperforms previously proposed channel access protocols for underwater networks by achieving higher throughput and lower energy consumption per bit delivered at nearly all traffic rates.
