Multi-channel MAC Protocol in Cognitive Radio Networks

Cognitive radio represents an efficient way to utilize the available spectrum in Wireless networks by offering the unlicensed users (Secondary users) the opportunity to use an available spectrum for the licensed users (Primary users) when they are not active. In this paper, some cognitive MAC protocols are discussed with a brief introduction to Multi Channel MAC protocols.

A Multi-Channel Hybrid MAC Protocol for Wireless Mesh Networks

In this article, the authors propose a new hybrid MAC protocol named H-MAC for wireless mesh networks. This protocol combines CSMA and TDMA schemes according to the contention level. In addition, it exploits channel diversity and provides a medium access control method that ensures the QoS requirements. Using ns-2 simulator, we have implemented and compared H-MAC with other MAC protocol used in...

A receiver-centric multi-channel MAC protocol for wireless networks

We consider the issues of mitigating interference and improving network capacity in wireless networks from the viewpoint of channel diversity. Multi-channel diversity allows multiple pairs to concurrently use the wireless medium, thus increasing the achievable capacity; this multi-channel diversity can then be fully utilized by enabling wireless nodes to dynamically switch their channels. Howev...

Multi-Channel MAC Protocol for Mobile Ad Hoc Networks

This paper introduces a new MAC scheme operating on multiple channels that maximizes network performance and provides differentiated services in mobile ad hoc networks (MANETs). Specifically, the IEEE 802.11 in ad hoc mode, the most popular MAC protocol in mobile ad hoc networks, is extended from single channel to multiple channels operation. The current standard allows the practical use of thr...
