In general wireless networks facing list of problems, these networks are deployed remotely with bad environment situations that leads affect on sensor device performance, it is possible to occur congestion due to limited bandwidth, limited processing capability there is a chance of data overflow, and no proper security mechanisms available. In reactive routing, to transfer data number of routes between sender to receiver are discovered, first shortest path is selected to transfer data, this route is available as long as no mobility of nodes, if route is expired due to network problems, and source must choose next optimal route. The route failure occurred due to movement of only one node and may waste bandwidth of wireless networks. It is a one of the major problem when mobility of nodes in the network are high and which may raise more number of route error messages. To solve route link failure problem, in this research paper we proposed new reliable network model, original network is surrounded with extra duplicate nodes, when a route link failure occur then use extra node to repair route, and no need to choose alternative path. Network reliability of proposed method is high when compared with other conventional routing protocols.
