Abstract
Battery lifetime is a crucial factor of a wireless device to support its mobility and quality. The system can answer to this issue by implementing cooperating protocols that attempt to reduce energy consumption. In an ideal system where no medium access control (MAC) layer is considered or no collision occurs, it has been proven that cooperation can reduce energy consumption. The existing MAC layer protocol might worsen the performance thus a new and improved scheme is needed for the scenario. This work proposes a new MAC scheme to solve energy consumption problem in cooperative wireless networks. The proposed scheme is simulated under a cooperative network model and compared with ideal system and existing MAC system. The results show that the proposed scheme gives significant improvement to existing system. Later, it is also simulated under several varying parameters, namely number of mobile devices, cluster ranges, strategies, mobility, and cluster periods.
