PROJECT TITLE :

A Cross-Layer MAC Protocol for Underwater Acoustic Sensor Networks

ABSTRACT:

One in every of the foremost challenges for the deployment of underwater acoustic sensor networks is the event of a medium access management (MAC) protocol catering for the cruel underwater setting. In explicit, an underwater MAC protocol should offer high end-to-finish throughput, low channel access delay, and honest share of the scarce network bandwidth. During this paper, a cross-layer MAC protocol is proposed. It interacts with a worth-primarily based rate allocation theme at the network layer. To accurately reflect the clique constraint of the wireless medium, the clique-based worth is generalized to act as the congestion signal, which controls the tip-to-finish rates of multihop flows. The MAC protocol then schedules rivalry-free packet transmissions of single-hop subflows in every maximum clique. Both the MAC protocol and rate allocation algorithm are straightforward and direct, therefore owning low computational complexity. Through analysis and simulation, we have a tendency to show that the proposed MAC protocol allows multihop flows to acquire the max-min truthful share of the network bandwidth from the end-to-finish perspective.
