With the increasing demand for network coverage and congestion-free network traffic, cooperative communication is getting more and more attention from network researchers. Cooperation communication is explored in a number of ways. Such various techniques are studied and one method is discussed in this paper. PRCSMA- Persistent Relay Carrier Sense Multiple Access Protocol is a very efficient protocol that gives good results for cooperative communication. This protocol is implemented using NS2 (Network Simulator). Its analysis is carried out in this paper. This will be useful to compare the advantages of cooperative communication over regular wireless communication.

Multiple Access Protocol

In this paper, we investigate the possibility of the cross-layer design of a distributed random access scheme with considering physical (PHY) and multiple access control (MAC) layers, which utilizes the interference cancellation technique. In this regard, we propose a new multiple access protocol, named carrier sense non-orthogonal multiple access (CSNOMA). We consider the spatially randomly distributed interferers to realistically capture the effect of interference. The proposed protocol shows better area spectral efficiency than carrier sense multiple access (CSMA), as the node density increases. We also present a practical signaling design compatible with IEEE 802.11 DCF mode.
