摘要：Power consumption in wireless ad hoc networks is an important design concern in the modern network research scenario. It is a concern because wireless nodes run with the help of battery and it has a limited life time period If the power failure of mobile node occurs it affects not only its ability to forward packets to destination but also its ability to forward packets on behalf of others and hence overall network lifetime. Moreover, it is very difficult to replace or recharge a mobile node powered by batteries so in order to maximize the life time of nodes routing of traffic should be in such a way that power consumption is minimized. Hence, every effort is to be channeled towards reducing power. More precisely, network lifetime is a key design metric in MANETs. Our main contribution in this thesis is Power Efficient Dynamic Source Routing (PEDSR) protocol, satisfying less power consumption from the viewpoints of nodes and network. To achieve our goal, first, we studied DSR protocol using performance and power aware metrics. Modifications are done on the Dynamic Source Routing (DSR) protocol by taking into consideration the outcomes of the pre-simulation, the existing feature of DSR for implementation of the design, and the previous research works done on DSR routing protocol by many researchers. Subsequently, we studied the performance evaluation of our proposition. The simulation results show that the power aware routing protocol, PEDSR outperforms the original DSR protocol in majority of the scenarios and evaluation metrics.
