A comprehensive review of position location technology—from fundamental theory to
advanced practical applications Positioning systems and location technologies have …

In the past two decades, a lot of research activities have been dedicated to the fields of
mobile ad hoc network (MANET) and wireless sensor networks (WSN). More recently, the …

We propose a novel framework for abnormal event detection in video that requires no
training sequences. Our framework is based on unmasking, a technique previously used for …

The research and use of positioning and navigation technologies outdoors has seen a
steady and exponential growth. Based on this success, there have been attempts to …

Position information of individual nodes is useful in implementing functions such as routing
and querying in ad-hoc networks. Deriving position information by using the capability of the …

We present TinyOS, a flexible, application-specific operating system for sensor networks,
which form a core component of ambient intelligence systems. Sensor networks consist of …

Signal processing on antenna arrays has received much recent attention in the mobile and
wireless networking research communities, with array signal processing approaches …

Wireless location refers to the geographic coordinates of a mobile subscriber in cellular or
wireless local area network (WLAN) environments. Wireless location finding has emerged …

We propose an optical wireless indoor localization using light emitting diodes (LEDs) and
demonstrate it via simulation. Unique frequency addresses are assigned to each LED lamp …

Monitoring applications define an important class of applications used in wireless sensor
networks. In these applications the network perceives the environment and searches for …
