As the field of communications networks continues to evolve, the challenging area of
wireless sensor networks is rapidly coming of age. Recent advances have made it possible …

Wireless sensor networks promise an unprecedented fine-grained interface between the
virtual and physical worlds. They are one of the most rapidly develo** information …

Preventing denial-of-service attacks in wireless sensor networks is difficult primarily because
of the limited resources available to network nodes and the ease with which attacks are …

This paper targets the identification of faulty sensors and detection of the reach of events in
sensor networks with faulty sensors. Typical applications include the detection of the …

In this paper, we consider two important problems for distributed fault-tolerant detection in
wireless sensor networks: 1) how to address both the noise-related measurement error and …

Given a set of sparsely distributed sensors in the Euclidean plane, a mobile robot is required
to visit all sensors to download the data and finally return to its base. The effective range of …

Sensor networks have emerged as a fundamentally new tool for monitoring spatially
distributed phenomena. This paper investigates a strategy by which sensor nodes detect …

Wireless sensor networks have created new opportunities for data collection in a variety of
scenarios, such as environmental and industrial, where we expect data to be temporally and …

This paper targets the identification of outlying sensors (that is, outlying reading sensors)
and the detection of the reach of events in sensor networks. Typical applications include the …

Wireless sensor networks (WSNs) have received considerable attention for multiple types of
applications. In particular, outlier detection in WSNs has been an area of vast interest …
