Abstract

Wireless Sensor Networks (WSNs) are being used for a large number of location-dependent applications, where the measurement data is meaningless without accurate location of its origin. In many of these applications, where coarse accuracy is sufficient, range free localization techniques are being pursued as low cost alternative to the range based localization techniques. Localization in WSNs is to determine the physical position of a sensor node based on the known positions of other sensor nodes having a priori knowledge of their position. In this paper, we present range free Circle weighted centroid localization. It’s an effective geometric algorithm for localization. Result of implementation show that this algorithm can be a better substitution for current methods because of lower expense and simple implementation. In these proposed techniques the weights of anchor nodes are obtained according to their proximity to the sensor nodes. We compared the proposed techniques, through extensive simulation with simple centroid and weighted centroid methods. The simulation results demonstrate the effectiveness of proposed schemes.
