Study on localization of moving objects using wireless sensor networks

This research argues that the process of ad-hoc localization of an object can be performed by wireless sensors. It also proposes a procedure which uses Received Signal Strength Indicator (RSSI) to estimate the distance and uses signal payload for direction. So, when wireless sensors are installed in objects such as vehicles in a defined orientation, they will be able to compute the distance as well as the direction of other incoming objects. This methodology provides relative positions of objects, however, it could be useful for various scenarios where setup of beacon nodes is unfeasible.
