In this paper we would like to share our experience for transforming a parallel code for a Computational Fluid Dynamics (CFD) problem into a parallel version for the RedisDG workflow engine. This system is able to capture heterogeneous and highly dynamic environments, thanks to opportunistic scheduling strategies. We show how to move to the field of “HPC as a Service” in order to use heterogeneous...
Electric vehicles (EVs) are viewed as an integral part of tomorrow's smart cities as they provide green alternatives as well as low-price solutions for traditional gasoline-based vehicles. However, the adoption of EVs by the users remain insipid. This is because of their limited battery capacity and longer recharging period compared to conventional vehicles. Therefore, to overcome these challenges,...
In this paper, the deployment of an unmanned aerial vehicle (UAV) as a flying base station used to provide the fly wireless communications to a given geographical area is analyzed. In particular, the coexistence between the UAV, that is transmitting data in the downlink, and an underlaid device-to-device (D2D) communication network is considered. For this model, a tractable analytical framework for...
Delay tolerant networks (DTNs) can be composed of multiple heterogeneous groups (i.e., communities) of nodes. The nodes from these communities can cooperate with each other in order to carry and forward data packets so that the performance (e.g., delay) can be improved. However, this cooperation will incur additional cost on the nodes. In this paper, we first develop an analytical model to investigate...
