Outlier detection has many important applications in sensor networks, eg, abnormal event
detection, animal behavior change, etc. It is a difficult problem since global information about …

Top-k monitoring is important to many wireless sensor applications. This paper exploits the
semantics of top-k query and proposes an energy-efficient monitoring approach called FILA …

Embedding small devices into everyday objects like toasters and coffee mugs creates a
wireless network of objects. These embedded devices can contain a description of the …

This article proposes content-based wake-up control for top-k query in wireless sensor
networks, where the sink attempts to collect information on top-k nodes or top-k values from …

Aiming at finding the k nodes with the highest readings among sensor nodes, top-k query is
a very important and useful query in wireless sensor networks (WSNs). Current studies …

In this paper, we consider the exact top-k query problem in wireless sensor networks, ie,
where one seeks to find the k highest reported values as well as the complete set of nodes …

Ranking queries are essential tools to process large amounts of probabilistic data that
encode exponentially many possible deterministic instances. In many applications where …

This paper presents a method for detection and recognition of road lane markings using an
uncalibrated onboard camera. Initially, lane boundaries are detected based on a linear …

Top-k query has long been an important topic in many fields of computer science. Efficient
implementation of the top-k queries is the key for information searching. With the new frontier …

Flash memory is the most prevalent storage medium found on modern wireless sensor
devices (WSDs). In this article we present two external memory index structures for the …
