Improving performance of MANET via cooperative communication with selective cooperation method considering dynamic traffic pattern using NS2

Generally Cooperative communication means network communication where nodes assist instead of contend to transmit data for themselves and other. Recently, there has been increasing interest in integrating multi-hop relaying functionalities into MANET. Multi-hop wireless networks can potentially enhance coverage, data rates. In this paper, we studied multi-hop cooperative communication and proposed a new multi hop cooperative protocol for dynamic traffic pattern. And we have compared the performance with selective relaying in MANET with dynamic traffic pattern using network simulator NS2.34. Throughput and packet delivery ratio are used as performance metrics for contrast. We are comparing the performance when the size of the packet changes, when the time interval between the packets are changed, when mobility of nodes changes.
