This report starts by giving an overview this project and its main objectives. It then gives a brief background of sensor networks and their applications. Various constraints and limitations of wireless sensor networks are outlined together with current methods of tackling these issues. It then describes benefits that mobility can introduce to sensor networks and presents current state of the art in this field. It then proceed to evaluate participatory sensing as part of this project in which a purpose built portable pollution sensing platfrom was built and tested. It also demonstrate how this platform was easily extended to surpass its original purpose and was later used as an indoor tracking module using RFID technology.
