Exploding demand for a growing number of wireless applications has fueled significant development of wireless network, especially several generations of cellular voice & data networks & more recently ad-hoc data networks for wireless computer, home & personal networking. To overcome the problem of wireless medium like fading and interference MIMO system can be used but due to size, cost or hardware limitations, a wireless node may not be able to support multiple transmit antennas.so the co-operative communication can be used as an alternative to MIMO. In this paper, we have discussed CO-OPMAC, cross layer protocol used for cooperative communication. Here, comparison between CO-OPMAC & IEEE 802.11 is presented. The CO-OPMAC protocol performs better than its legacy IEEE 802.11 in terms of throughput, delay & achieves higher spatial diversity.

Keywords: Co-operative communication, comparison of results of IEEE 802.11 & Co-op.MAC protocol, Cross layer approach.
