Improved Performance of Enhanced Receiver Initiated Packet Train (E-RIPT) for Underwater Acoustic Networks

This paper proposes a Modified Enhanced Receiver-Initiated Packet Train (ME-RIPT) Media Access Control (MAC) protocol for an underwater acoustic network. It is designed specifically for underwater acoustic sensor networks, which is characterized by low data rate and long propagation delay. We design a new control signaling which alleviates the exposed problem. The simulation result shows improvement in throughput, delay, and fairness compared to its predecessors, RIPT and E-RIPT for various environment settings.
