摘要
栅栏覆盖中相邻的连通异构节点可以通过数据融合进行协作地感知以提高检测准确性并减少构建栅栏的活跃节点数量.首先提出一个基于数据融合的异构协作监测覆盖模型,其次分析了影响栅栏覆盖生命期的因素,并将其描述为一个多目标优化问题,最后,基于该优化模型,提出了增强覆盖图的概念.实验结果表明,基于本文提出的覆盖模型和增强覆盖图的活跃调度算法在网络生存期与覆盖率方面的性能明显高于它们在传统覆盖模型中的性能.
Collaborations and data fusion between connected heterogeneous neighboring sensors in barrier coverage can help to improve the accuracy of detection and reduce the number of active sensors needed to cover a barrier.In this paper,we first formalize a coordinated heterogeneous detection coverage model.Then,we analyze the influencing factors of barrier coverage lifetime,and tranfer it to a multiobjective optimization problem.Based on it,we propose the concept of enhanced coverage graph.Simulations show that the same active sensors scheduling algorithms based on the coordinated heterogeneous detection coverage model and enhanced coverage graph provide effective enhancement in coverage probability and lifetime,compared with their performance based on traditional coverage models.
