Long propagation delay, limited bandwidth and high bit error rate pose great challenges in Media Access Control (MAC) protocol design for underwater acoustic networks. A reservation based MAC protocol called R-MAC designed for underwater acoustic networks was proposed and analyzed. However, there exists channel resources waste problem in R-MAC. In order to overcome this drawback, this paper proposes...
Event-driven wireless sensor networks (WSNs) usually operate under light traffic load. However, when an event is detected, a large number of packets may be generated. A MAC protocol designed for this kind of WSNs should be able to swiftly adapt to the two conditions. Most WSN MAC protocols are optimized for light traffic for the energy efficiency consideration. In this paper, we propose a novel receiver-centric...
