Mobility in Wireless Sensor Networks may significantly affect the network performance. This
paper proposes distributed algorithm that improves the network coverage and connectivity …

We propose a novel distributed deployment algorithm for sensor networks whose nodes
reside upon and are obstructed by 2.5 D terrain. Our algorithm optimizes area coverage by …

Sensor networks aim at monitoring their surroundings for event detection and object
tracking. In practice, due to failure or death of sensors, false signal can be transmitted. In this …

Wireless Sensor Networks (WSNs) have been an active research area these years due to
their broad range of potential applications. Several research issues, which include energy …

When deploying a wireless sensor network in an unknown environment, commonly referred
to as Region of Interest (ROI), the main goal is for the entire region to be covered by the …

In focused coverage problem, sensors are required to be deployed around a given point of
interest (POI) with respect to a priority requirement: an area close to POI has higher priority …

Since sensor networks integrate virtual and physical worlds, spatial deployment of sensor
nodes may have a significant impact on operation costs and performance. This paper …

In this paper, we consider the coverage problem in wireless sensor and actuator networks
composed of static sensors dropped stochastically in a region of interest (ROI) which is a …
