Abstract

The lifetime of a mobile ad hoc network (MANET) depends on the durability of the battery resources of the mobile hosts. Earlier research has proposed several routing protocols specifically for MANET, but most studies have not focused on the limitations of battery resources. The failure of battery resources severely impacts a communications system during natural disasters and in crucial communications environments, such as a battlefield. This study proposes a new energy-aware routing protocol that can increase the durability of the energy resource and, therefore, the lifetime of the mobile hosts and the MANET. The proposed protocol can conserve energy by shortening the idle period of the mobile hosts without increasing the probability of packet loss or reducing routing fidelity. Simulation results indicate that this new energy-conserving protocol can extend the lifetime of a MANET.
