Position Estimation in Ad hoc Wireless Sensor Networks with Low Complexity

چکیده
− In sensor networks, randomly distributed sensor nodes have to determine its own positions to assign measurements to locations. Due to limited resources of the nodes, resourceaware positioning algorithms are required. In this paper, we present a solution to minimize the positioning error of the “Weighted Centroid Localization” algorithm (WCL) using hop count determination. Compared to other approximative algorithms, WCL achieves a remarkable average positioning error below 8%. Further, we introduce abstract distances to support different types of distance information, e.g. hop count determination or distance measurements. Finally, we present an analytical equation to compute a qualified transmission range in scenarios with hop count determination.
