Abstract

Since the packages from different nodes collide with each other frequently in Ad Hoc networks, it is hard to guarantee QoS of Real-Time multimedia services if only adopting traditional multi-channel MAC protocols such as DCA, MMAC, etc. In this paper, a new multi-channel MAC technology called MAC-MC is proposed. Under MAC-MC protocol, the wireless channel is divided into one control sub-channel and N service sub-channels. The nodes in Ad Hoc network exchange RTS/CTS messages in the control sub-channel to reserve the service sub-channel for dada package. The access mechanism in the control sub-channel is designed basing on DIFFSERV mode. The parameters value of the Real-Time service package CW is different to that of Best-Effort service packages, so that the Real-Time service packages can obtain the higher priority to access the control sub-channel. In addition, a bi-dimension Markov mode is presented to analyze the performances of MAC-MC protocol theoretically. The results via simulation show that: Compared with MMAC protocol, the transfer delay of Real-Time service package is decreased greatly under the MAC-MC protocol; the networks throughput under MAC-MC protocols is larger than the networks throughput under IEEE 802.11 EDCF protocols.
