Mesh clients have a higher variety of devices compared to mesh routers. The architecture of WMNs can be categorized into three main groups : A. The client Wireless Mesh Networks It provides peer-to peer networks among devices. Client nodes constitute the actual network to perform routing and configuration functionalities as well as providing enduser applications to customers. Therefore , a mesh router is not required for these types of networks. In this type of mesh network, a packet destined to a node in the network hops through multiple nodes in order to reach the destination. The networks are usually formed using one type of radios on devices. The architecture is shown in figure 1. B. Infrastructure of WMN These types of networks are the most commonly used which include mesh routers forming an infrastructure for clients that connect to them. The WMN infrastructure can be built using various types of radio technologies, in addition to the mostly used IEEE 802.11 technologies. The mesh routers form a mesh of self-configuring, self-healing links among themselves. With gateway functionality, mesh routers can be connected to the Internet. This method can also be referred to as infrastructure mesh￾ing. It provides backbone for conventional clients and enables integration of WMNs with existing wireless networks, through gateway/bridge functionalities in mesh routers. Conventional clients with Ethernet interface can be connected to mesh routers via Ethernet links. For conventional clients with the same radio technologies as mesh routers, they can directly communicate with mesh routers. If different radio technologies are used, clients must communicate with the base stations Fig. 2. Infrastructure of WMN Fig. 3. Hybrid of WMN that have Ethernet connections to mesh routers. For example, community and neighborhood networks can be built using infrastructure meshing. The mesh routers are placed on the roof of houses in a neighborhood, which serve as access points for users inside the homes and along the roads. The mesh backbone communication can be established using long-range communication techniques including directional antennas. See figure 2. C. The Hybrid of WMN The hybrid wireless mesh networks architecture is basically the merging of client meshing and infrastructure. Mesh clients can access the network through mesh routers as well as directly meshing with other mesh clients. While the infrastructure provides connectivity to other networks such as the Internet, Wi-Fi, WiMAX, cellular, and sensor networks; the routing capabilities of clients provide improved connectivity and cov￾erage inside the WMN. See figure 3. III. THE CAPACITY OF WMN Mobile ad hoc networks were the first wireless mesh net￾works whereby wireless stations were moving around and participating in a peer to peer network. Mobile peer to peer networks benefit from the sparse connectivity requirements of the mesh architecture; and the combination of wireless and
