ABSTRACT: Wireless mesh networking (WMN) is an emerging technology
that enables multihop wireless connectivity to areas where wiring or installing
cables is difficult or expensive. Multicast is a form of communication that
delivers information from a source to a group of destinations. In a
single-channel WMN, all nodes share and communicate with each other via the
same channel. In such a network, the throughput capacity of multicast degrades
significantly as the network size increases. A critical factor that contributes
to this rapid degradation is the co-channel interference in single-channel
WMNs. The major advantage of WMN is that power is not the major issue as
compare to other wireless network like MANET, Sensor etc. Hence Power can be
optimally utilized in WMN to increase throughput and total network efficiency.
In this paper, we propose a channel assignment algorithm for multicast based on
high channel capacity with minimum interference. This scheme usesall
overlapping and non overlapping channel for the channel assignment. By this
scheme we provide better performance in terms of average packet delivery ratio,
average throughput and average end to end delay with respect to multichannel
multicast channel assignment schemes.
