Connection-oriented multi-channel MAC protocol for ad-hoc networks

This work proposes an on-demand connection-oriented multi-channel MAC protocol for ad-hoc networks. The major features of the proposed protocol are as follows: (a) each mobile node is equipped with only two network interfaces; (b) MAC layer broadcast primitive is supported; and (c) no time synchronization is required. Compared with other multi-channel MAC protocols, the proposed protocol reduces the cost of channel negotiation by considering the property that a connection typically generates multiple packets for transmitting. The NS-2 is used to evaluate the performance of the proposed protocol. Simulation results indicate that the proposed protocol can reduce the cost of channel negotiation and increase the network throughput.
