Keywords : wireless sensor network (WSN), localization techniques, multidimensional scaling (MDS) Abstract :Wireless Sensor Network (WSN) is a wide area used for different applications in today’s scenario. Knowing the position of each node in the sensor network is very essential. Wireless sensor network is useless without localization information about each sensor node. Using GPS to find the position of sensor node is costly and power consuming solution. Also, it is not useful for indoor applications. So, we need to use localization algorithms. In this paper, we located the positions of unknown nodes in wireless sensor network by implementing an algorithm based on multidimensional scaling (MDS) technique. Distance matrix is calculated using different methods. To increase accuracy we have used distance approximation to refine distance matrix. We examined the performance of our algorithm for different network topologies and parameters by conducting simulations. From simulation we conclude that the algorithm performs well in terms of accuracy.
