移动传感器在入侵检测的应用研究中，感兴趣区域主要考虑的是特定形状，如圆形或矩形。由于这种限制，很多研究结论通用性差。研究了感兴趣区域是任何形状的一个环；基于移动传感器的速度，移动模式和数量，建立了一个随机模型；分析多个或单个移动传感器沿环检测的性能。在模型中，当所有移动传感器检测时，它们被置以恒定的速度周期性地沿环移动。对于多个移动传感器，它们的速度都相同。入侵事件的模式为每次入侵到达环上一个随机点，抵达后停留一个随机时间长度。根据移动传感器的数量，导出了移动传感器对入侵漏捕概率和首次捕获入侵所需平均时间的一般表达式。最后，评估了移动传感器的检测性能。

As to the application of the mobile sensor in the intrusion detections,one of the results is that the sensory areas are believed to be a specific shape,such as a circular or a rectangular. Because of this limitation,conclusions from a lot of relevant research are greatly confined to certain fields. In this paper,the sensory areas are proved to be a loop of different sizes, and a random model is designed according to the speed of the mobile sensor and the schedule and the number of its moving. Then,the detection performances of a single or multiple mobile sensors along the loop are analyzed. In the model,when all the mobile sensors are being detected,they are found to move at a constant speed along the loop periodically. When multiple mobile sensors are working, the speed of them is the same. The mode of the intrusion is as follows:each intrusion arrives at a random point on the loop,then stops and stays for a random length of time. According to the number of the mobile sensors,the general expressions of the loss capture probability of intrusion and the average time required for the mobile sensors capturing intrusion for the first time are generalized. Finally,the detection performance of the detection sensor is evaluated.
