Choosing the shortest path for real-time flows is insufficient. Respecting the deadline cannot be insured nor guaranteed neither with exhausted energy resource nor with overloaded intermediate mobile nodes. The main problem is to choose the reliable, efficient and correct routing protocol to route real-time flows with respect to their deadlines within MANET constraints. This paper introduces the Energy Delay aware based on Dynamic Source Routing, ED-DSR. ED-DSR efficiently utilizes the network resources such as the intermediate node energy and load in order to balance traffic load. It ensures both timeliness and energy efficiency by avoiding low-power and busy intermediate node. Simulation results, using NS simulator, improve that the protocol increases the volume of delivered packets in-time (around 50% for the data flows with strict deadline and around 63% with non-strict deadline), prolongs the network lifetime (up to 66%) and shortens the end-to-end delay.
