摘要：This paper proposes an accurate, low cost and power efficient localization algorithm for Wireless Sensor Networks (WSN). The algorithm uses a Received Signal Strength (RSS) measurement technique and a mobile anchor node equipped with a GPS and a directional antenna. The algorithm does not depend on specific ranging hardware requirements for sensor nodes, Moreover; the algorithm needs only one anchor node to achieve high localization accuracy. Performance evaluation of the proposed algorithm is done using MATLAB. The results show that the proposed algorithm achieves a high localization accuracy by reducing the localization error by 66.53%. Moreover it extends the nodes lifetime by reducing the reception energy consumption by 95.94% compared to DIR localization algorithm introduced in [10].
