Wireless mesh network (WMN) is a peculiar type of growing technology that can alter the world more effectively in the coming decades. Multicast routing in mesh networks is the distribution of data from a single source to multiple destinations or multiple sources to multiple destinations through the intermediate nodes. There can be many numbers of intermediate nodes between source and destination....
Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers, because of their potential use in several fields such as collaborative computing and communications.

For wireless mesh networks using the IEEE 802.11 family of standards, carrier sensing mechanisms such as physical carrier sensing and virtual carrier sensing play a key role in determining goodput and overall network performance. However, inaccurate modelling of the effect of carrier sensing on goodput leads to poor decision making in mesh network roll out. More accurate models can be derived by analysing...
