Actually many Internet of Things (IoT) applications and architectures are being deployed in order to support urban area applications, as for example smart cities. However, other important applications are being deployed in rural areas, as for example agribusiness, in which wireless connectivity is one of the most important issues because wireless broadband commercial technologies are not sustainable...
In this letter, we address the following problem: given a mesh network deployment and $|\mathbb{G}|$ gateways to be added, what is the optimal gateway placement with the constraint of energy-minimization for green wireless mesh networks. Unlike previous research, which focuses on throughput optimization, we contribute by developing a mixed-integer linear programming (MILP) formulation, which satisfies...
The Wireless Body Area Networks (WBAN) is an emerging type of real-time monitoring used in the healthcare sector. It has the potential to revolutionize the healthcare sector by allowing patients not to physically visit doctor clinics or hospitals for medical checkups. But implementing such a system is challenged by many factors. The most important one is energy consumption. Energy consumption of all...
Energy efficiency is a crucial challenge in cluster-based capillary networks for Internet of Things (IoT) systems, where the cluster heads (CHs) selection has great impact on the network performance. It is an optimization problem to find the optimum number of CHs as well as which devices are selected as CHs. In this paper, we formulate the clustering problem into the CHs selection procedure with the...
