English Abstract

Many localization techniques in wireless sensor networks (WSN) have been investigated recently.

These techniques were usually aimed to how locate unknown nodes or how to improve performance of localization.

In this thesis an improved localization algorithm depend on range-free technique in (WSN) using a mobile anchor node which is equipped with GPS receiver to obtain its position.

The mobile anchor node moves around sensing field with certain trajectory starting form certain point out of the sensing filed to a destination point with constant speed broadcasting beacon messages with certain radius including its location information.

Each stationary sensor node takes information and calculates its location by computing the intersection area for four beacon nodes using centroid algorithm in its communication area.

And whenever the intersectional area for four beacon nodes decreased the localization error (m) reduced.

After the first round of localization, unknown sensor nodes can compute their locations with help of localized sensor nodes.

A mathematical model was introduced and analyzed.

MATLAB simulation results demonstrated that the accuracy of the proposed localization technique using mobile anchor node is better than the other techniques
