Wireless mesh networks

Seminar topic on Wireless mesh networks :Wireless mesh networks(WMN) is formed by radio node and it belongs to mesh topology.Generally it consist of  mesh clients,routers and gateways.WMN's are implemented by one of wireless technology's 802.11,802.15,802.16 or combination of more than one wireless technology's.In WMN's if any node failure that may not effect the other nodes in the communication.So WMN's is reliable .If one node fail, then rest of nodes form communication.Main applications of Wireless mesh networks are environment monitoring,public safety and citywide wireless Internet services.
