An Enhanced Path Planning Model for Anchor-Free Localization in Wireless Sensor Networks

In Wireless Sensor Network (WSN), localization stands as a major challenge which is intended to maximize with minimized traveling distance of the beacon node. Further, the important issue is to improve coverage and accuracy in calculation of the location. This paper mainly focuses on an enhanced path planning model using beacon node. The proposed model focuses to improve coverage of the network topology by moving in zig-zag fashion so that it will enhance the reachability of message in almost every corner of the deployed area. The proposed model is simulated extensively in a self simulator with different scenarios and compared with SCAN and anchor based model. The tested performance of the model is presented along with its analytical model. The simulation result shows that the proposed model outperforms by 1% to 2% than the existing model in terms of percentage of nodes settled and energy consumption.
