Location awareness is an attractive research issue in the wireless sensor network (WSN). However, precise location information may be unavailable due to the constraint in energy, ...
The localization problem is important in mobile robots and wireless sensor network and has been studied for many years. Among many localization methods, the hop-count based approa...

Location information is very useful in the design of sensor network infrastructures. In this paper, we study the anchor-free 2D localization problem by using local angle measureme...
—In this work we study the problem of query privacy in large scale sensor networks. Motivated by a novel trust model in which clients query networks owned by trusted entities but...
— In a wireless sensor network (WSN), the sensor nodes (SNs) generally localize themselves with the help of anchors that are pre-deployed in the network. Time of Arrival (ToA) is...
