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. (C) 2008 Elsevier B.V. All rights reserved.
