Analyzing Object Detection Quality Under Probabilistic Coverage in Sensor Networks

Coverage Quality in Visual Sensor Networks

Unauthenticated event detection in wireless sensor networks using sensors co-coverage

Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...

Intrusion Object Detection of a Randomized Scheduling Algorithm in Wireless Sen- sor Network

In wireless sensor networks, which can be configured to put some sensor nodes in sleep mode to save energy. This approach is a special case of a randomized scheduling algorithm, in which k subsets of sensors work alternatively. In this paper, we first study the performance of the randomized scheduling algorithm via both analysis and simulation in terms of intrusion coverage intensity, and detec...

A Max-Flow Based Algorithm for Connected Target Coverage with Probabilistic Sensors

Coverage is a fundamental issue in the research field of wireless sensor networks (WSNs). Connected target coverage discusses the sensor placement to guarantee the needs of both coverage and connectivity. Existing works largely leverage on the Boolean disk model, which is only a coarse approximation to the practical sensing model. In this paper, we focus on the connected target coverage issue b...

LPKP: location-based probabilistic key pre-distribution scheme for large-scale wireless sensor networks using graph coloring

Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
