The Temporally Ordered Routing Algorithm (TORA) is an adaptive distributed routing algorithm for multihop ad hoc networks. It was intentionally build for fast changing network topologies. The protocol is based on the link reversal concept. TORA uses destination oriented routing information that is already available at each node. Nodes only need to know their one-hop neighbourhood. Based on the neighbour information TORA creates independently local routing information for each destination node. The destination oriented routing principle allows reactive, proactive and combined concepts. Furthermore TORA was drafted to be able using multiple routes and absence of loops[1]. In this paper OPNET simulation tool is used for analysing the performance of TORA routing protocol .In this simulation scenario different networks are used to measure the performance of TORA routing protocol. The experimental study has delay and throughput parameters. The simulation results of the research have practical reference value for further study.
