N2 - 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 an improved R-MAC based MAC protocol for underwater acoustic networks, called NR-MAC. To improve the channel utilization, NR-MAC introduces a new control packet called xREV. Then a new mechanism for data sending and receiving is designed and improved scheduling algorithms at receiver are proposed. Simulation results show that NR-MAC increases the network throughput as compared with R-MAC.
