Multicast Routing Protocol With Low Transmission Delay in Multi-Rate, Multi-Radio Wireless Mesh Networks
Wireless Mesh Networks (WMNs) have received much attention as a promising broadband access infrastructure in both urban and rural environments. Their low equipment and deployment costs extend network connectivity and make Internet services available to a larger community. Accordingly, end users are connected to a gateway through a multi-hop mesh consisting of stationary wireless routers. However, in such a multi-hop wireless network, there are many problems to be solved for reliable communication. One of the key challenges is bandwidth scarcity. In order to overcome this shortcoming, three themes have recently been under extensive research: Multi-Rate, Multi-Radio and Multi-Channel (MR2-MC) capabilities.
