Abstract
Using multi-channel MAC protocols in mobile ad hoc net- works (MANETs) is a promising way to improve the through- put performance. Channel assignment, which directly de- termines the e±ciency of the frequency utilization, is the critical part of multi-channel schemes. Current 802.11-like schemes of multi-channel MAC do not e±ciently use the multiple channels due to the overhead caused by channel assignment. Moreover, the control channel saturation prob- lem limits the number of channels of these previous schemes. In this paper, we propose a new scheme called SAM-MAC (Self-Adjustable Multi-channel MAC), which features with one common channel and two half-duplex transceivers for each node. A method called self-adjustment is used to reas- sign the channels and balance the tra±c on di®erent chan- nels. Due to less contention in common channel and smaller channel assignment overhead, this scheme increases the through- put compared with previous approaches. Control channels are free from saturation problem and can furthermore be used for data transmission.
