A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links.When designing mobile ad hoc networks, several interesting and difficult problems arise because of the shared nature of the wireless medium, limited transmission power (range) of wireless devices, node mobility, and battery limitations.This paper aims at providing a new schema to improve Dynamic Source Routing (DSR) Protocol.The aim behind the proposed enhancement is to find the best route in acceptable time limit without having broadcast storm.Moreover, O-DSR enables network not only to overcome congestion but also maximize the lifetime of mobile nodes.Some simulations results show that the Route Request (RREQ) and the Control Packet Overhead decrease by 15% when O-DSR is used, consequently.Also the global energy consumption in O-DSR is lower until to 60 % , which leads to a long lifetime of the network.
