Abstract

In this paper we propose a new MAC protocol for ad-hoc underwater acoustic sensor networks that segregates the available bandwidth into a (small) control channel and a (majority bandwidth) data channel. Reservations for main channel time are made by transmission of request-to-Send(RTS) packets on the control channel. The effects of channel segregation are explored and simulation results are presented. We find that such a reservation MAC generally achieves good channel utilization with an optimal control channel bandwidth for a given data bandwidth.
