    Abstract: Barrier coverage is known as one of the most important applications in wireless sensor networks. Most existing studies adopted the Boolean Sensing Model (BSM) which assumes that sensor can detect the object falling in the sensing range of that sensor. Another sensing model, called Elfes Sensing Model (ESM), which assumes that the probability of sensing is a probabilistic value depending on the distance between sensor and object. The ESM model is more practical than BSM model since it considers the interference and other environmental conditions. This paper considers the ESM and proposes a distributed mechanism, called BSQ (Barrier coverage for guaranteeing Surveillance Quality), for constructing a barrier coverage. The proposed BSQ aims to maximize the weakest sensing quality of barrier boundary while satisfying the minimum numbers of sensors. Experimental study reveals that the proposed BSQ outperforms existing related schemes in terms of surveillance quality and hardware cost.
