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.
