一种基于数据融合的传感器网络部署方案
Deployment scheme of sensor networks based on data fusion
摘要
Abstract
Based on probability sense model of the exponential decay law, this paper proposed the concept of virtual radius to quantize the improvement on network coverage performance caused by data fusion, while it proposed the concept of fusion coverage and virtual deployment as well. Then, proposed a regular virtual deployment scheme based on regular polygon and analysed the effect on deployment density of sensor nodes caused by this deployment scheme. The theoretical analysis indicates that the number of nodes which were participated in fusion process of virtual radius was no more than 6. Otherwise data fusion will not reduce the node density, on the contrary, it will have a negative effect on the node density. Meanwhile, coverage schedule of these nodes which were deployed in the random distribution has also been analyzed, and proposed an improved the coverage schedule algorithm based on virtual radius. Finally, it did some experiment simulations. By using the data fusion algorithm based on the exponential decay law, the experimental result indicates that data fusion algorithm can effectively improve the detection performance of sensor networks, in addition, the regular virtual deployment scheme based on regular polygon can effectively improve the coverage performance of sensor networks, as the schedule algorithm based on virtual radius do, which sensor nodes deploy in random way.关键词
