Traditional methods for monitoring the environmental factors of a greenhouse and the
growth of Phalaenopsis orchids often suffer from low spatiotemporal resolution, high labor …

One of the critical concerns in wireless sensor networks (WSNs) is the continuous
maintenance of sensing coverage. Many particular applications, such as battlefield intrusion …

Local Positioning Systems (LPS) have shown excellent performance for applications that
demand high accuracy. They rely on ad-hoc node deployments which fit the environment …

The traditional Low Energy Adaptive Cluster Hierarchy (LEACH) routing protocol is a
clustering-based protocol. The uneven selection of cluster heads results in premature death …

Local Positioning Systems (LPS) have become an active field of research in the last few
years. Their application in harsh environments for high-demanded accuracy applications is …

Currently, global warming is worsening, causing the difficulty of cultivating crops in open
fields, and leading to unstable quality of crops. Plant factories provide a well-controlled …

Developing an autonomous early warning system for detecting pest resurgence is an
essential task to reduce the probabilities of massive Oriental fruit fly (Bactrocera dorsalis …

Maintaining effective coverage and extending the network lifetime as much as possible has
become one of the most critical issues in the coverage of WSNs. In this paper, we propose a …

Minimum energy broadcast (MEB) problem in wireless sensor network has attracted
attentions of the many researchers due to the limited bandwidth of the network and battery …

We define two generalized types of a priority queue by allowing some forms of changing the
priorities of the elements in the queue. We show that they can be implemented efficiently …
