Robust Routing and Tracking in Constrained Mobility Scenarios, Demonstrated at ACM Sensys 2006

The system model that we considered for this project was that the nodes in the network are neither static nor completely ad-hoc; rather, there is constrained mobility of nodes. Moreover the mobile nodes are resource constrained but present in high density and the network is asymmetric in the sense that there is a powerful base station. The goals of this project were (a) Online tracking of mobile objects at base station using noisy RSSI measurements (b) Localization of mobile nodes for use in middleware services such as routing (c) Proactive asymmetric maintenance of connectivity of mobile nodes to/from base station, for convergecast, broadcast, and unicast (d) Experimental study of impact of mobility on quality of structure. This system was deployed in the context of an application that tracks visitors (tagged with a TELOS mote) in a poster presentation area and continuously monitors the number of visitors to each poster, and demonstrated at Sensys 2006.
