In three-dimensional space, the traditional algorithm of virtual force applies to continuous target tracking process is prone to problems of distraction and short time in keeping tracking of the target in the process of. This paper proposed a three-dimensional space deployment algorithm applies to continuous target tracking to solve these problems. The combine virtual force in this algorithm is generated...
A belt region is said to be k-barrier covered by a set of sensors if all paths crossing the width of the belt region intersect the sensing regions of at least k sensors. Barrier coverage can be achieved from a random initial deployment of mobile sensors by suitably relocating the sensors to form a barrier. Reducing the movement of the sensors is important in such scenarios due to the energy constraints...
In order to save the mobile sensor network energy and improve the barrier coverage with mobile sensor network to adapt to the environment. The virtual force principle is applied in low power RF(Radio Frequency) wake-up mobile sensor nodes and obstacles. Some of sensor nodes are in the state of work, the others are dormant. When the sensor network is damaged, the dormant sensor nodes can be waked up...
Wireless sensor networks consist of a large number sensors spread across a given geographical area. Each sensor has its own communication capability as well as certain level of intelligence for signal processing and networking. As the sensor nodes are densely populated, communication range requirement for these nodes is smaller. After signal detection, a number of sensor nodes communicate over the...
In this paper, we study the issue of sensor network deployment using limited mobility sensors. By limited mobility, we mean that the maximum distance that sensors are capable of moving to is limited. Given an initial deployment of limited mobility sensors in a field clustered into multiple regions, our deployment problem is to determine a movement plan for the sensors to minimize the variance in number...
