摘要：Localization is one of key issues in MANET. It provides information about coverage, deployment, routing, location service, target tracking and rescue. If high mobility among the Mobile nodes occurs, path failure breaks. Hence the location information cannot be predicted. Here, we have proposed an Localization based Optimized Energy Routing (ELOER) based on cluster and energy consumption model to provide location information of nodes based on Trilateration method. Proposed approach consists of three phases. In first phase, Cluster head is chosen based on energy level. In second phase, location aided routing is chosen to alleviate computation cost and save Mobile nodes energy. In third phase, localization method is developed to improve accuracy and reduce node degree. To locate the target and Mobile Nodes Discrete Fourier Transform and distributed algorithm was used. By simulation results, the proposed approach ELOER achieves high location updated rate, improved network lifetime, less end to end delay and overhead in terms of mobility, pause time, throughput, and number of nodes than existing protocol ALARM.
