Energy efficient greedy forwarding method over MANET based on three-hop information

This paper proposes a method that can reduce the energy consumption of battery-driven nodes over MANET by modifying location aided greedy forwarding protocol based on considering information of three-hop away nodes. Our approach determines the suitable path to make sure the path will consume as low energy as it can be. Our algorithm can switch relay nodes by considering the number of hops that are located between source and destination to fulfill the minimum energy consumption and prolong network lifetime. We compare our approach with existing algorithms through computer simulation and analysis. The simulation results show that our approach can achieve lower energy.
