Wireless Mesh Network (WMN)
A wireless mesh network (WMN) is a communication network made up of nodes which act as radio transmitters, organized in a mesh topology. Nodes can communicate directly with one or more peer nodes.  The signal propagates through the network wirelessly form one to another and then finally to the destination. Basically there are three types of architectures used for connecting nodes in mesh: Fixed Mesh Networks, Peer to Peer Mobile Networks and Node-To-Node Network. WMNs consist of two types of nodes: Mesh Clients and Mesh Routers. There are two basic modes of implementation: infrastructure and/or client meshing. Hybrid Mesh Networking is also used sometimes to gain the maximum benefit so that both modes can be supported simultaneously and seamlessly in a single network. There are some Critical Design Factors like Radio Techniques, Scalability, Mesh Connectivity and Broadband and QoS that determine the performance of the network.  The main characteristics of WMNs that make it popular are multi-hop wireless network connectivity, mobility dependence on the type of mesh nodes, multiple types of network access and compatibility and interoperability with existing wireless networks.
