Abstract: Localization of sensors is an important and an integral issue for wireless sensor networks control and operation. Definite self-localization competence is immensely desirable in a wireless sensor network. A prominent complication in distance oriented localization of wireless sensor network is whether a given sensor network is cognizable or not. This paper introduces an innovative and computationally proficient localization method for WSN that uses Tabu Search (TS) based global optimization on the results of Hill Climbing based local optimization for the location computation and optimization of sensor nodes. From the performance analysis of this integrated method it is prominent that in spite of memory demands, TS-based method has superior convergence characteristics compared to other earlier proposed WSN localization techniques. Also, trends in the recent years have shifted to the hybrid optimization methods i.e. optimization by hybridization of metaheuristics and other techniques. This greatly reduces localization error and computation time for large networks. In the proposed system hill climbing local search method is implemented along with tabu search algorithm for efficient localization.
