Wireless Mesh Networks (WMNs) are a class of Next-Generation Networks (NGN) that provides one of the most promising solutions to improve network coverage, deliver community broadband Internet access services and reduce deployment cost. In such networks, communications between two nodes can be supported by intermediate nodes called Mesh Routers (MRs). Fig.1 illustrates a relatively static infrastructure of a WMN composed by three types of wireless routers. The routers which connect the clients to the requesting service are called Access Points (APs). The relays route the traffic to other relays via a point-to-point connection until a router with an Internet connection is found. Such a wireless router is called a Mesh Gateway (MG).
