Jamming represents the most serious security threat in the field of wireless sensor networks
(WSNs), as it can easily put out of order even WSNs that utilize strong highlayer security …

Since battery technology has not progressed as rapidly as semiconductor technology, power
efficiency has become increasingly important in wireless networking, in addition to the …

Methods, devices, and systems that store occurrence-data gathered by a distributed sensor
network. In an approach, an exemplary method includes receiving a target-occurrence …

Jamming is defined as the act of intentionally directing electromagnetic energy towards a
communication system to disrupt or prevent signal transmission. In the context of wireless …

We investigate the problem of converting sets of sensors into strongly connected networks of
sensors using multiple directional antennae. Consider a set S of n points in the plane …

Middleware is a critical foundation needed to leverage the development of a wide range of
mobile and ubiquitous applications. Intrinsic challenges when building such middleware …

Efficient exploitation of multiple antenna capabilities in ad hoc networks requires carefully
designed cross-layer techniques. The work presented in this paper provides a medium …

Using directional antennas to conserve bandwidth and energy consumption in ad hoc
wireless networks has attracted much attention from the research community in recent years …

In a hostile environment, it is important for a transmitter to make its wireless transmission
invisible to adversaries because an adversary can detect the transmitter if the received …
