Energy optimization technique for distributed localized wireless sensor network

摘要

Several localization techniques have been proposed to identify the exact location of sensor nodes. Localization is important for computation of many applications such as routing in wireless sensor network. Energy preservation is a challenge in wireless sensor network and many algorithms have already been proposed. The localized node lifetime is maximized by using energy-efficient routing, use of minimum number of layers in communication and by minimizing their active time. In this paper a technique which will optimize the energy in routing algorithm by reducing the number of active sensors in communication is proposed. Major performance factors are network throughput, latency and message complexity. In energy optimization these factors are considered and an optimized solution for localization with high accuracy is proposed.
