Energy-based route discovery mechanism in mobile ad hoc networks

A novel energy-efficient routing protocol (on-demand technique) is proposed here in order to utilize the energy consumption in mobile ad hoc network. Our protocol proposes a route discovery technique based on energy cost. The energy cost represents energy consumption of the network in order to sustain all connections between source and destination nodes. The proposed algorithm was evaluated through realistic energy consumption modeling, which used the channel quality to decide whether each packet is successfully received. Simulation results show that the proposed algorithm outperforms other reviewed algorithms, shortest-path (SP), re-transmission-aware routing protocol (RA) and condition min-max battery capacity routing (CMMBCR). By using the proposed algorithm, the energy consumption of network is reduced by 12 % compared to RA in high mobility scenario
