The Routing is the process of transmitting data packets from one node to another another node from source to destination The Mobile Adhoc Networks (MANETs ) doesn't have any fixed network structure or any centralized process to administer. The selection of the route is important for performance of packet transfer from source to destination. These routing protocol are classified as inter domain routing and Intra domain routing protocol. The routing protocols have been classified into Non Reactive , Reactive and Hybrid protocols. In the present paper we proposes to compare reactive routing protocols videlicet Ad hoc On Demand Distance Vector (AODV), Dynamic Source Routing (DSR) protocols, Temporarily Ordered Routing Algorithm (TORA) and Associativity Grounded Routing (ABR) protocol.The Routing in MANETs is a one of the robustly and demanding task and has entered a great quantum of mindfulness from experimenters around the globe. To overcome this problem, a colorful number of routing classes have been introduced and the number is still rising day by day fastly. It's relatively hard to decide which protocols or routing classes may do well under an quantum of different network scripts similar as network volume and network topology etc. The study and performance of the above mentioned protocol has also been tabulated in the present two tables . The protocols are based on minimum power and temporary configuration of topology. The table 1 gives comparison of the main characteristics of routing protocols and Table2. provide comparison of various reactive routing protocol.
