Comparing to well protected data frames, Wi-Fi management frames (MFs) are extremely
vulnerable to various attacks. Since MFs are transmitted without encryption or …

Many applications of location based services (LBSs), it is useful or even necessary to ensure
that LBSs services determine their location. For continuous queries where users report their …

This article discusses the use of unmanned aerial vehicles (UAVs) to detect, warn, and
suppress forest fires. The proposed system consists of: 1) an energy harvesting-assisted …

Numerous indoor localization techniques have been proposed recently to meet the intensive
demand for location-based service (LBS). Among them, the most popular solutions are the …

We present SmartLoc, a localization system to estimate the location and the traveling
distance by leveraging the lower-power inertial sensors embedded in smartphones as a …

We propose an accurate acoustic direction finding scheme, Swadloon, according to the
arbitrary pattern of phone shaking in a rough horizontal plane. Swadloon leverages sensors …

Data aggregation is an essential yet time-consuming task in wireless sensor networks. This
paper studies the well-known minimum-latency aggregation schedule problem and …

The existing mobile beacon based range free localization method has two basic
problems:(1) the accuracy of position estimation depends on closer beacon broadcasting …

Area-based localization algorithms use only the position of some reference nodes, called
anchors, to estimate the residence area of the remaining nodes. Existing algorithms use a …

Data missing is a common problem in wireless sensor networks. Currently, to ensure the
performance of data processing, making imputation for the missing data is the most common …
