| Popis: | In an Internet of things (IoT) context, the existence of multiple technologies, that ensure communication between each node and the entire network, aims to improve the overall capacity to satisfy the growing number of connected devices. However, to meet a high performance, it is important to assign the right device to the right radio access technology (RAT). In this paper, we are interested in a radio access technology selection in an IoT context. We answer the question how to select the right RAT taking into account two main parameters: energy efficiency and cost to connect to a RAT, and using two different approaches. The first one is a fully distributed approach that allows to devices to autonomously select the best RAT that meets their preference requirement, but also satisfies the RATs access points utilities. The second approach relies on a centralized entity that ensures association between IoT devices and RATs using a binary knapsack optimization problem. The results obtained through simulations show that when it comes to energy efficiency and fairness among devices, the matching approach outperforms the knapsack based scheme. |
