Design and Analysis of Analytical Model of Novel Energy Constrained Cooperative Mac Protocol for Ad-hoc Networks

Relay assisted cooperative wireless communication has been shown to have significant performance gains over the legacy direct transmission scheme for Ad-hoc network. An efficient cooperative Medium Access Control Scheme (MAC) is needed to solve the difficulties induced by relaying and cooperative computing. Another challenging issue is the extension of network lifetime of an Ad-hoc network with regards to small battery capacity and self sustained operation. So, designing energy constrained cooperative MAC for improving the network lifetime is a challenging task. Yet, only less attention has been paid for cooperative MAC scheme and its potential for lifetime extension. In this paper, we propose a novel Energy Constrained Cooperative MAC protocol namely ECC-MAC for Ad-hoc networks with the objective of maximizing the network lifetime and achieving high throughput. Furthermore, we presents an analytical model for network lifetime aware cooperative MAC scheme which identify the best possible relay based on both residual energy and data rate. We show that the proposed model seeks to optimize the tradeoff between network lifetime and throughput.
