Multi-link Passive Localization with Low Cost in Wireless Sensor Networks

摘要

Wireless localization technology has become an important application in wildlife conservation. However, such systems require carrying devices in wildlife unsuited to wildlife conservation, or costing larger energy consumption under the large-scale area, impeding their wide-scale adoption. This poster introduces Trepli, a multi-link animal localization system in large-scale area. Unlike the previous work which needs the target to participate in during the localization, Trepli presents a wireless localization approach using received signal strength indicator (RSSI) without any human or target efforts which called passive localization. Our key contribution is low cost that can turn the large-scale positioning area into the small one using selected random deployment of three links. Finally we obtain the target location using the target localization algorithm on this small area. We evaluate its performance through real-world deployment and simulation experiments. Experimental result shows that Trepli is feasible to achieve target localization with low cost in theory.
