Study of Hybrid Localization Noncooperative Scheme in Wireless Sensor Network

Abstract EN

In this paper, we evaluated the experiment and analysis measurement accuracy to determine object location based on wireless sensor network (WSN).

The algorithm estimates the position of sensor nodes employing received signal strength (RSS) from scattered nodes in the environment, in particular for the indoor building.

Besides that, we considered another algorithm based on weight centroid localization (WCL).

In particular testbed, we combined both RSS and WCL as hybrid localization in case of noncooperative scheme with considering that source nodes directly communicate only with anchor nodes.

Our experimental result shows localization accuracy of more than 90% and obtained the estimation error reduction to 4% compared to existing algorithms.
