Development of software for localization of stationary wireless sensor nodes (non-reviewed)

Summary form only given. Localization is the process of finding the geometric location of a wireless sensor node according to some real or virtual coordinate system. Localization is an important task when direct measurements of the wireless sensor locations are not available. Effective localization algorithms can use available information from wireless sensors to infer position of individual node. Various techniques have been evolved in localizing sensor nodes. In this work, passive localization algorithms are developed and tested. The algorithms perform region based localization of stationary wireless sensors with respect to a frame of reference using received signal strength of the sensors. The reported work is conducted in two phases, theoretical development then hardware testing. In the first phase, localization algorithms to predict the location of wireless sensor nodes were developed. We categorized localization of sensors in three different scenarios.
