Burst Mode Cooperative MAC Protocol in Ad Hoc Wireless Networks

Free registration required

Executive Summary

Cooperative Medium Access Control (MAC) Protocols make use of the multi-rate capabilities of IEEE 802.11 to achieve higher throughput and shorter delay. This is achieved through transmitting a packet via a helper node by means of a faster two-hop links rather than a slower direct one-hop link. The Cooperative MAC protocol transmits only one packet from the source node for each successful transmission attempt in the channel. In this paper, the authors extend this Cooperative MAC protocol such that it is capable of transmitting multiple packets for each successful transmission attempt in the channel in an Ad Hoc Wireless Network. Furthermore, two traffic classes are considered. They call this new proposed MAC protocol as Burst Mode Cooperative MAC.
