Enhanced DV Hop Localization Algorithm for Wireless Sensor Networks

The Wireless Sensor Networks Localization is an important area due to its wide spread application in the all fields. Hence in this work, an improved Distance Vector technics is used to reduce the localization error of target nodes in the wireless sensor networks. The proposed technique is an modification over classical D V hop algorithm. The importance of localization of unknown sensor nodes in WSN is an emerging area due to the wide use of applications. Hence in this paper, an advanced Distance Vector algorithm is proposed to improve the localization or positional accuracy of unknown sensor nodes. The proposed algorithm is an enhancement over traditional over classical Distance Vector algorithm. The main goal of this algorithm is minimize the error generated during the calculation of average hop size value with the help of weighted correction on average hop size. And further improvement in positional accuracy of sensor node is maintained by using WLS algorithm, by considering the distance between anchor nodes and unknown sensor nodes. Simulation results are generated by using MATLAB and the localization accuracy or error compared with classical DV hop, improved method by changing the parameters like radius of communication of nodes, density of sensor nodes and percentage of anchor counts.
