Most of previous studies assume that the sensing range of deployed sensors is based on Binary Sensing Model. However, in reality, the sensing range of sensor is based on Probability Sensing Model. By considering that the sensor is movable and its sensing range is probability sensing model, this paper proposed a relocation mechanism which aims to improve detection probability of barrier coverage in Mobile WSNs. Besides, the given monitored region also satisfies the predefined requirement of network lifetime. Compared with related works, experimental studies reveal that the proposed relocation mechanism can effectively improve the detection probability of barrier coverage while satisfies the predefined requirement of network lifetime.
