Abstract: WMNs are one of the insufficient commonly applied types of Mobile Ad-hoc NETworks (MANETs); several companies offer WMNs for broadband Internet access and for spreading the attention of wireless local area networks. Several particularities differentiate WMNs from MANETs. Principal, in WMNs, most of the circulation originates or terminates at the gateways (nodes connected to the wired infrastructure/Internet). Additional, in most requests, WMN nodes incline to be neatly distinguished as either stationary nodes or mobile nodes (utilizing the coverage afforded by the stationary nodes). Routing Protocol is an important typical of mesh topology network. The strengths and fault of routing protocols are reflected directly in WMNís characteristics. Numerous compensations of WMNs over competing skills are directly enabled by the routing protocols. WMNs necessitate routing procedures that provide suppleness to work with different topologies, low latency for route (re-) discovery, low control traffic overhead, scalability with respect to mobility and network dimension, moveable user support, efficient delivery, QoS support, multicast which is significant for emergency response cases and more desirable one multipath. This paper reviews on various types of routing protocols that are used in wireless mesh networks. An evaluation of properties and proposed classification of WMN routing protocols. Also authors tried to make an evaluation of different structures of selected routing metrics and characteristics of selected routing protocols.
