An important problem in wireless ad hoc and sensor networks is to select a few nodes to form a virtual backbone that supports routing and other tasks such as area monitoring. Prev...
Wireless Sensor Networks (WSNs) have received considerable attention in recent years and opened up new possibilities for various commercial and industrial applications. A WSN cons...
In many sensor networking environments, the sensor nodes have limited battery capacity and processing power. Hence, it is imperative to develop solutions that are energy-efficient...
The problem we address in this paper is how to detect an intruder moving through a polygonal space that is equipped with a camera sensor network. We propose a probabilistic sensor ...
In this paper, we study the problem of data gathering in multi-hop wireless sensor networks. To tackle the high degree of channel contention and high probability of packet collisi...
