A Survey on Load Balancing Gateway Selection Techniques in Wireless Mesh Networks
Wireless Mesh Networks (WMNs) are developing to be the key technology of the next generation wireless network. As the WMNs are envisioned to provide high bandwidth broadband service to a large community of users, it is attracting the wireless internet service providers. Internet Gateway (IGW) which acts as a central point of internet attachment for the mesh routers, it is likely to be a potential bottleneck because of its limited wireless link capacity. Indeed, if traffic is routed in the mesh without considering traffic distribution, as well as link capacities, some gateways may rapidly get overloaded due to unevenly utilization of network resources. So, whenever the users intend to communicate with the outside networks via the internet gateways the load of the internet gateway must be balanced to a void overloading any gateways. In this paper we discuss about various load balancing techniques of gateway selection.
