Ledo: Location-Based Distribution Energy Optimization Protocol In Wireless Sensor Networks

Researches on efficient wireless routing protocols have attracted a lot of attention recently. The classic wireless routing protocols, such as AODV and DSR, are distance-driven and table-driven, which are rarely addressing the energy consumption issue. Therefore, it is necessary to develop a new network protocol that can provide higher energy efficiency and achieve longer network lifetime. Considering the limited power supply of sensor nodes, we proposed a Location-based Energy Distribution Optimization (LEDO) routing protocol that is based on the node location information and the balanced energy consumption strategy. The performance evaluation of LEDO and the performance comparison with AODV and DSR has been done basing on NS-2 simulator platform. The simulation results show that the LEDO effectively balances the energy consumption of nodes and extends the network lifetime.
