摘要： 研究移动目标在可移动传感环境下的反监控问题，设计一种新的暴露模型，用于估计布置了大量可移动各向异性传感器节点的区域中，目标沿路径进行穿越时的暴露程度。基于该模型，利用各向异性Voronoi网格，提出一种判决算法，该算法使目标穿越监控区域时，可以选择合适的、暴露程度较小的穿越路径。理论分析和实验结果表明，该算法实用性和可靠性较高。

Abstract: This paper research the anti-monitor problem of mobile object in the mobile sensory field and designs a new exposure model, which can be used to estimate the exposure degree when a mobile object is moving along a path to traverse the sensory field deployed with lots of mobile anisotropic sensor nodes. Based on the model, a decision algorithm is proposed by using Voronoi grid, which guarantees the mobile object to select a suitable path with approximately minimal risk to travel across the mobile anisotropic sensory field. Theoretical analysis and simulation results show that this algorithm is practicable and reliable.
