This paper proposes an enhanced mobile ad-hoc routing protocol FSR (Fast and Secure Routing), which is enhanced version of best features of ZBR (Zone Based routing Protocol). FSR deals with speed and security both at the same time. The ZBR enhances the speed of the network whether TCP has provided the primary means to transfer data reliably across the Internet. Modern networks routinely drop packets when the load temporarily exceeds their buffering capacities. Early detection protocols have tried to address this problem with a user-defined threshold, the finding of detecting and removing compromised routers can be thought of as an instance of anomalous behaviour based intrusion detection. That can be the compromised router can that identified by correct routers when it deviates from exhibiting expected behaviour. This protocol can be evaluated in a small experimental network.
