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...

G/S model is a new type of spatial information network service model, based on distributed network architecture, which organizes, manages data to achieve client-aggregation-service via HGML. A solution of remote video monitoring system is raised by the study of G/S model. Intuitive data for the user are provided by the distribute network, which is used for monitoring geographic information and displaying...
Directed on the lack of coverage differentiation of the conventional Virtual Force Algorithm (abbr. VFA) deployment algorithm to monitoring area leading to low utilization of network resources, a Self-Deployment Algorithm of Mobile Sensor Network Based on Uniform Density Cluster is presented in this article. Through construction of a virtual gravitational force at the deployment center, and construction...
In order to resolve the problems of network segmentation, coverage holes and unable to conduct key monitoring upon specific target area by the conventional virtual force algorithm (abbr. VFA) in sparse network environment, a Multi-center Self-deployment Algorithm (abbr. MCSA) is presented hereby. Through construction of virtual repulsive force between nodes as well as a virtual attraction force field...
To reduce the cost of abundant mobile sensors deployed in unknown environment, a target-oriented self-deployment algorithm (TSA) based on attracting force line is proposed. By designing the attracting force line and constructing virtual attracting force and repulsive force, the paths between sink and targets are set up automatically. Simulation results show that the proposed algorithm compared to...
Sensor network is usually composed of static nodes or mobile nodes. In order to achieve maximum performance, deployment of nodes should maximize coverage. The deployment of static sensor network is simple, but random location can not ensure the better connectivity. At the same time, the cost of mobile sensor network which consists of only mobile nodes is much high. In this paper, a virtual force based...
In order to enforce the sensing performance of mobile sensor network (MSN), an enhanced self-deployment (ESD) algorithm is proposed in this paper. By designing the virtual repulsive force between nodes, the movement equation and the virtual attracting-field in the sensing area, the problems of the network partition and coverage holes which are aroused by conventional potential-field-based deployment...
