Abstract

Wireless Mesh Network is a promising network standard as it provides reasonable and inexpensive solutions for various types of applications. In the recent times, it has gradually developedin the direction of Multi-Radio Multi-Channel Wireless Mesh Network(MRMC WMN) architecture, which improves performance of network by providing multiple radio interfaces to every node in the network and by equipping several non-overlapping channels. In this paper, research work of variousauthors has been analyzed and found that various authors proposed modified channel assignment techniques to improve the network performance.Lot of different methods and techniques are used by them to reduce the co-channel interference. It is found that very few authors measured the traffic flow in network for channel assignment. It is asalient area and it must be carefully examined during the channel assignment. In this study, it is observed that traffic flow along with power control and topology control must be considered for efficientchannel assignment.Channel assignment is essential to make sure the best possible utilization of a few numbers of channels in the frequency spectrum.Efficient utilization of MRMC WMN can be obtained by intelligent and dynamic channel assignment.
