...destination. Then a RREP is sent back to the source and the discovered route is made available. Note: Fresh Enough route is a valid route entry for the destination whose associated sequence number is at least as great as that contained in RREQ. Nodes that are part of an active route may offer connectivity information by broadcasting periodically local hello messages (special RREP messages) to its immediate neighbors. If hello messages stop arriving from a neighbor beyond some given time threshold, the connection is assumed to be lost. When a node detects that a route to a neighbor node is not valid it removes the routing entry and sends a RERR message to neighbors that are active and use the route; this is possible by maintaining active neighbor lists. This procedure is repeated at nodes that receive RERR messages. A source that receives an RERR can reinitiate a RREQ...

In this paper, Wireless Mesh Network over MANET implemented using routing protocols such as AODV, DSR. In this work NS-2.34 simulator is used for simulations. Various measurements and calculations were figure out in this work like throughput, Average end-end delay, PDR, NRL and Routing packets in Random way point mobility model. WMN have features such as self configuration, self healing and low cost of equipment. This work specifically aims to study the performance of routing protocols in a wireless mesh network, where static mesh routers and mobile clients participate together to implement networks functionality such as routing and packet forwarding in different mobility scenarios Keywords- Ad hoc Network, Routing Protocols, Wireless Mesh Network, Performance, Throughput, PDR, NRL and Routing packets...
