Advantages of Node Energy Control for Routes Selection in Wireless Sensor Networks

Wireless sensor networks are characterized for being composed for a large number of nodes that are distributed geographically in a monitoring area. Considering this distribution and the restrictions of processing, memory and energy of this equipment, it becomes primordial to use mechanisms to increase its lifetime through the better use of the network resources. One of the ways to allow this improvement is the evaluation of the nodes´ resources in the routing protocols, avoiding routes composed by nodes with little energy in the selection process. To deal with this requirement this work presents a protocol created based on the AODV algorithm to improve the energy consumption of the nodes, mainly of whom already presents a capacity. The simulations show that the proposed algorithm reached better results than other evaluated routing algorithms
