Power consumption is a crucial design concern in mobile ad‐hoc networks (MANETs), since the nodes are powered by batteries with limited battery power, whereas the existing dynamic source routing (DSR) protocol does not take the battery power limitation of the MANET nodes into account. The mobile hosts in MANETs are constrained by the battery power for their operation. Hence, the battery power of a node is a precious resource that must be used efficiently in order to avoid early termination of a node or a network. In the MANET, power is one of the major issues, since the devices have limited battery power to execute the tasks. This study proposes a new scheme called efficient power routing DSR (EPRDSR) to improve the existing on‐demand routing protocols by introducing a power efficient scheme in the whole MANET. In the route discovery, the EPRDSR selects the bandwidth and the power constraints are built into the DSR route discovery mechanism. Hence, it enhances the network lifetime and delays the repair and reconstruction of the route. The main goal of EPRDSR is not only to extend the lifetime of each node, but also to prolong the lifetime of each connection.
