An Effective Localization Based Optimized Energy Routing for Wireless Sensor Networks

Localization is one of the more important tasks in Wireless Sensor Networks. The accurate location information could greatly improve the performance of tasks such as routing, energy conservation, data aggregation and maintaining network security. Here, we have proposed an Efficient Location Optimized Energy Routing (ELOER) approach which attains to make a balance between network life times, location updated rate and delay among the sensor nodes. In the first phase of the scheme, multipath routing is proposed. In second phase, sensor election scheme is deployed to save energy of sensor nodes. In third phase, localization algorithm is proposed based on energy and trilateration method. In four phase, packet format is proposed. It contains following factors location update rate, location estimated field to favour better route selection and reduce energy consumption of sensor nodes. By simulation results we have shown that the ELOER achieves high network lifetime, high location update rate, while attaining low end to end delay, low overhead than the existing scheme ELMARP and ALARM while varying the number of nodes, speed, mobility and pause time.
