Wireless ad hoc network is characterized by autonomous nodes communicating with each
other by forming a multi hop radio network and maintaining connectivity in a decentralized …

We propose an energy-efficient network architecture that consists of ad hoc (mobile)
cognitive radios (CRs) and infrastructure wireless sensor nodes. The sensor nodes within …

κ-barrier coverage is one of the critical issues in directional sensor networks. In actual
application, the sensing distance becomes small with the increase of sensing angle, and the …

Network lifetime and energy consumption are major issues in wireless sensor networks
while protection of the primary user is the most important activity in a cognitive radio network …

In this paper, a new cooperation structure for spectrum sensing in cognitive radio networks is
proposed, which outperforms the existing commonly used ones in terms of energy efficiency …

The coverage problem is critical for wireless sensor network. The quality of coverage is the
key factor of service quality. The network holes can decrease the network connectivity and …

Deployment of wireless sensor networks on 3D complex surface is an important and
fundamental issue to be solved. The existing studies focus on the plane coverage and 3D …

In this paper, one of the fundamental problems of coverage in Wireless Sensor Networks
(WSNs) is addressed. Coverage, answers the questions about quality of service that can be …

Coverage is one of the important issues in WSNs, which can measure the service quality of
sensors deployed in the sensing region. Comparing with the traditional detection model, ie …
