Location based Energy Efficient Routing Protocol for Improving Network Lifetime in WSN

Localization in sensor networks produces major impact to improve network lifetime of nodes Cluster formation and Cluster head election is the key criteria for increasing energy efficiency of network. In existing schemes, the focus on cluster and localization with multi-hop environment is not considered and balanced to attain stable network. In this research, a Dynamic Energy Efficient Localization model is explored to reduce energy consumption through geographical position of nodes. In this work, cluster region is formed with sever nodes and Cluster Head (CH)is elected based on significant parameters i.e., node energy, delay between nodes and distance between nodes. These parameters are maintained at threshold level to choose cluster head. Network topology is created with vertices to ease the deployment of node with most accuracy. Multiple paths are discovered to route the packets with the selection of reliable path and least route metric. Data transmission begins with efficient route establishment and localization of cluster members with most accuracy and least localization error. Simulation results are taken and analysed using Network simulator tool and network performance metrics i.e., location accuracy, delay, packet delivery ratio, throughput, packet least percentage was taken and shows the improvement in proposed model.
