On-Demand Connection- Oriented Multi-Channel MAC Protocol for Ad-Hoc Network

Abstract

This paper presents an on-demand connection-oriented multi-channel MAC protocol for ad-hoc networks. The major characteristics of proposed protocol are: (a) each mobile node is equipped with two network interfaces, (b) frame broadcasting is supported and (c) no time synchronization is needed. Compared with other multi-channel MAC protocols, the proposed protocol reduces the cost of channel negotiation by considering the property that a connection generates multiple frames for transmitting. NS-2 is used to evaluate the performance of the proposed protocol. Simulation results show that the proposed protocol can reduce the cost of channel negotiation and increase the network throughput
