We study a heterogeneous two-tier wireless sensor network in which N heterogeneous
access points (APs) collect sensing data from densely distributed sensors and then forward …

With the rapid growth of the internet of things (IoT), an impressive number of IoT's application
based on wireless sensor networks (WSNs) has been deployed in various domain. Due to …

The motivation for writing this book came from our previous research works on sensor
coverage. They received a large number of citations and this number grows rapidly each …

Coal mine shafts are narrow, the environment is complex and changeable, the wired
monitoring system has poor scalability, complicated wiring, and high costs and maintenance …

Internet of Things (IoT) is characterized by a system of interconnected devices capable of
communicating with each other to carry out specific useful tasks. The connection between …

The processing of data and signals provided by sensors aims at extracting relevant features
which can be used to assess and diagnose the health state of the monitored targets …

We investigate parameterized algorithms for the NP-hard problem Min-Power Asymmetric
Connectivity (MinPAC) that has applications in wireless sensor networks. Given a directed …

Constrained maximization of non-decreasing utility functions with submodularity-like
properties is at the core of several AI and ML applications including viral marketing, pool …

Target coverage (TCOV) and network connectivity (NCON) are the most basic problems
affecting robust data communication and environmental sensing in a wireless sensor …

Advances in optimization and constraint satisfaction techniques, together with the availability
