Mission critical services have stringent requirements in terms of reliability, energy-efficiency
and performance. Optimisation approaches are required to maximise missions' service time …

The work presented in this paper is demonstrated by the design of the framework/algorithm
and the ability to implement a method for analysing network performance in order to achieve …

The use of wireless sensor networks has been increased substantially. One of the main
inconveniences of this kind of networks is the energy efficiency; for this reason, there are …

The IEEE 802.11 ah standard is intended to adapt the specifications of IEEE 802.11 to the
Internet of Things (IoT) scenario. One of the main features of IEEE 802.11 ah consists of the …

Abstract The Restricted Access Window (RAW) mechanism proposed by IEEE 802.11 ah
promises to address one of the major problems of the Internet of Things (IoT): high channel …

Nowadays, wireless access networks are already amongst the top power consumers in the
ICT (Information and Communication Technology) sector. As it expected that these networks …

Although traditionally Wireless Sensor Network (WSNs) have been regarded as static
sensor arrays used mainly for environmental monitoring, recently, its applications have …

Wireless networks operate in rapidly changing environments. Often parameters for particular
algorithms are set with particular environments in mind, or assume certain conditions. When …

In high-density wireless sensor networks, the quality of service in terms of sensing coverage,
connectivity, lifetime, energy consumption and cost is closely linked to the position of the …

The reduction of the energy footprint of large and mid-sized IEEE 802.11 access networks is
gaining momentum. When operating at the network management level, the availability of an …
