	A [[Wireless Mesh Network]] (WMN) is a multi-hop wireless network. Usually, WMNs consist of Mesh Routers (MR), Mesh Clients (MC), and Gateways (GW). Mesh Routers and Gateways form the infrastructure of the network and provide access to the Mesh Clients which are often laptops, cellphones, PDAs and other devices. Often the Mesh Routers are assumed to be fixed and non mobile but this is not always the case. The Mesh Routers are also often assumed to have access to greater resources (CPU, Memory) than MCs. These characteristics separate a WMN from a [[mobile ad hoc network]] (MANET). In a MANET, all nodes are generally limited by battery life, CPU and Memory resulting in protocols and algorithms which are tailored to conserving these resources. In a WMN, the MRs can be taken advantage of when designing protocols that have greater performance.		A [[Wireless Mesh Network]] (WMN) is a multi-hop wireless network.
