Abstract :
A new asynchronous medium access control (MAC) protocol with cooperative channel reservation, called CCRM, is proposed. Compared with legacy channel reservation MAC protocols, where channel reservation information (CRI) can not be obtained reliably due to either transmission errors or packet collisions, CCRM improves the reliability of channel reservation using cooperative channel reservation mechanism. In CCRM, CRI originated from nodes bearing real-time traffic is further relayed by the cooperation of neighboring nodes. Simulations show that CCRM can significantly reduce the transmission failure rate (TFR) for real-time traffic especially in scenarios with either error-prone wireless channels or heavy traffic loads.
