Wireless Sensor Networks (WSN) has been proposed as a solution to environment sensing, target tracking, data collection and other applications. Sensor positioning is one of the important problems in WSN. Strong antenna arrays at each node or sensor arrays at different positions are used to localize the sources. This paper proposes a sensor positioning algorithm for WSN. A comparative analysis is made for proposed method along with existing methods with respect to computational cost, shortest path, and number of nodes, radio range and ranging error. The results show that proposed method: iterative routing algorithm provides improved performance over existing methods in the aspects considered.
