Abstract:

In this paper, we propose a MAC layer cooperative multicast strategy based on the IEEE 802.11 protocol, in which correctly received data can serve as a temporary relay if the user locates a right position. We analyze the outage probability and throughput performance of the proposed strategy, and present a simulation method in NS2. Simulation results show that the new strategy has a better throughput and lower packet loss performance compared to the original MAC protocol.

Key words: wireless multicast, cooperative communication, Network Simulator 2, IEEE 802.11 protocal
