A Dynamic Channel Allocation Scheme Using Spectrum Sensing for Mobile Ad Hoc Networks

Executive Summary

An important aspect of the MAC layer design for Mobile Ad hoc NETworks (MANETs) is the ability to adapt to spatially non-uniform traffic load distributions. While coordinated channel access protocols have been shown to be well suited for highly loaded MANETs, these protocols are in general not as well suited for non-uniform load distributions as uncoordinated channel access protocols. In order to improve the performance of coordinated MAC protocols for MANETs under non-uniform load distribution, in this paper the authors apply to MANETs the dynamic channel allocation concept used in cellular networks. They present a new coordinated MAC protocol called DCA-TRACE (Dynamic Channel Allocation for TRACE), which is a sequel of their earlier MH-TRACE protocol.
