This paper is about how to achieve the development and implementation of FSR routing protocol in Ad hoc network based on OPNET simulation framework. The analysis of the routing protocol FSR based on table-driven is followed by the implementation of the protocol via OPNET modeling simulation tool in terms of Ad hoc network features. The application prospect of FSR in Ad hoc network is obtained through the comparison of performances such as time delay and load of FSR, AODV and OLSR.
