Medium access control (MAC) protocols coordinate channel access between wireless stations, and they significantly affect the network throughput of wireless ad hoc networks. To function normally, MANETs demand an efficient and distributed MAC protocol. We first discuss the challenges that are facing MAC in MANETs. Then we proposed an effective protocol scheme for energy efficiency.
Due to their dynamic topologies, providing quality of service (QoS) in wireless ad hoc networks introduces major new challenges to the research community. Now, the commercially available ad-hoc network products are those based on the IEEE802.11 Distributed Coordination Function (DCF). Cooperative communications fully leverages the broadcast nature of the wireless channel and spatial diversity, thereby...
