The usage of wireless sensor networks (WSNs) to monitor a region is an important
functionality in defense and security applications. In these applications, a fundamental issue …

Recently, wireless sensor networks have attracted a lot of attention. Such environments may
consist of many inexpensive nodes, each capable of collecting, storing, processing …

Sensing coverage is a fundamental problem in wireless sensor networks (WSNs), which has
attracted considerable attention. Conventional research on this topic focuses on the 0/1 …

Coverage is a fundamental problem in sensor networks. In this paper, we addressed the
coverage problem from two different view points and refer to them as the worst and best …

As an important issue reflecting the QoS of the sensing task, coverage problem impacts
widely on the performance of wireless sensor networks. The target coverage lifetime …

We consider a wireless sensor network consisting of a set of sensors deployed randomly. A
point in the monitored area is covered if it is within the sensing range of a sensor. In some …

Coverage problem is an important issue in wireless sensor networks, which has a great
impact on the performance of wireless sensor networks. Given a sensor network, the …

In this paper, we study the problem of scheduling sensor activity to cover a set of targets with
known locations such that all targets can be monitored all the time and the network can …

Coverage problem is a fundamental issue in wireless sensor networks. In this paper, we
consider two sub-problems: k-coverage rate evaluation and k-coverage rate deployment …

Coverage is a fundamental problem in wireless sensor networks since sensors may be
spread in arbitrary manner. In this paper, we addressed the k-support coverage problem …
