Multichannel Reservation Protocol in Ad-Hoc Networks

In area where there is a little or no infrastructure or the existing infrastructure is inconvenient to use, wireless mobile users may still be able to communicate through the formation of an Ad Hoc network. The protocol of medium access in Ad Hoc networks with the time-varying network toplogy is related to the efficiency of network. Recently, since the method using multichannel can obtain higher throughput than conventional methods using single radio channel, some protocols have been researched, such as CATS. For CATS, there is a problem that the transmission will be deadlocked in case of high load. In this paper, improving backoff algorithm of media access scheme over single radio channel used as the control channel in Ad Hoc network, we propose a novel protocol for channel reservation named multichannel reservation protocol (MCRP) and provide estimates of its performance. The results show that the proposed protocol can work well even in case of high load with no deadlock.
