An Energy and Load-Based Routing Algorithm in Wireless Sensor Network

In wireless sensor networks, limiting energy consumption of sensors and prolonging the network lifetime have been important reasons to evaluate routing protocol´s performance. This paper proposes a routing metric, which takes into remaining energy and load of the sensor nodes, trying to balance network traffic and protect the low-power and high-load nodes. Base on this metric, we also propose a new routing algorithm called Energy and Load-based Routing (ELR). Simulation results show that the new method can even load distribution and node energy.
