Enhancing channel utilization in mesh networks

In this paper wireless mesh networks, IEEE 802.11-based network whose nodes are either user devices or access points, is considered. Regarding some work done within the 802.11s TG, we present an analytical model of our proposed MAC scheme [Khayatzadeh Mahani A, Naderi M, Casetti C, Chiasserini CF. Enhancing channel utilization in mesh networks. IEEE MILCOM, Orlando, FL, 2007], distributed queue dual channel (DQDC), in which the nodes use one control channel and one or more data channels each on separate frequencies. Also a new channel reservation scheme based on DQDC MAC protocol is presented to decrease total average transmission delay. Finally we show that the reservation schemes achieve low transmission delay in comparsion with DQDC and standard 802.11 protocol.
