<br />With the explosive growth of the Internet and wireless networks, especially Wireless Mesh Networks (WMNs), are going through an important evolution. Designing efficient WMNs has become a major task for networks operators.<br />A wireless mesh network (WMN) is a communications network made up of nodes organized in a mesh topology.<br /><br />Components of WMN<br /> Mesh Routers (MR)<br /> Mesh Clients (MC)<br /> Gateways<br /><br /> <br />Mesh Client – Mesh Router Links <br />◦ Wired (e.g. Ethernet, etc.)<br />◦ Wireless (e.g. 802.11x, Bluetooth, etc.)<br />Mesh Router – Mesh Router Links<br />◦ Wireless (e.g. 802.11x)<br />Gateway – Internet Links<br />◦ Wired (e.g. Ethernet)<br />◦ Wireless (e.g. 802.16)<br /><br /><br />Architectures of WMN<br /> Infrastructure/Backbone WMNs<br /> Client WMNs<br /> Hybrid WMN<br /><br /><br /> <br />Applications of WMN<br /> Home smart<br /> Health and Medical Systems<br /> Transportation Systems<br /> City networks<br /><br />WMN advantage<br /> low cost technology<br /> large coverage area<br />
