Localization in wireless sensor network by using mobile stations

Being aware of nodes position is very important and one of the base issue in wireless sensor networks. To calculate sensor nodes location, many algorithms use radio waves. Wireless sensor networks include of sensor nodes with limited power, low memory and less processing capability. One of the requirements of localization algorithms is low energy consumption. In this article a new localization algorithm is proposed which uses only one mobile station to find nodes position with high accuracy and acceptable speed. Proposed scheme is scalable and suitable for all kind of wireless sensor networks with different density of nodes.
