Abstract: One of the main design constraints in mobile Ad Hoc networks (MANETs) is that they are power constrained. Hence, every effort is to be channeled towards reducing power. More precisely, network lifetime is a key design metric in MANETs. The typical MANET routing protocols of (AODV, DSR and DSDV) are shortest routing protocols, that is, the least hops but do not consider the energy efficiency of the routes. Our goal in this thesis is to propose Active Communication Energy Efficient routing mechanisms and protocols, satisfying less energy consumption from the viewpoints of nodes and network. To achieve our goal, first, we studied the three typical MANET routing protocols (AODV, DSR and DSDV) using performance and energy aware metrics. The simulation results show that DSR outperforms the other two routing protocols in majority of the scenarios and evaluation metrics. Our main contribution in this thesis is energy efficient routing protocol. It addresses energy aware link cost computation and route discovery. The link cost is derived based on energy aware parameters such as transmission power between the nodes, the residual battery energy of nodes, receiving power and queue length. The routing mechanism also addresses delay forwarding to minimize broadcast storm. This energy efficient routing protocol is named Energy Efficient Dynamic Source Routing (EEDSR). It modifies the Dynamic Source Routing (DSR) protocol by taking into consideration the results of the pre-simulation, the existing feature of DSR for implementation of the design, and the previous works on MANETs routing protocols. Subsequently, we studied the performance evaluation of our proposition. The simulation results show that the energy efficient routing protocol, EEDSR outperforms the original DSR, in limited battery energized nodes. EEDSR saves about 25.97%-70.5% of ECSDD and prolongs the network lifetime about 15.74%-84.71% compared to DSR. In addition, EEDSR provides better PDF than DSR
