Channel modelling and performance analysis of V2I communication systems in blind bend scattering environments
Chelli, Ali; Hamdi, Rami; Alouini, Mohamed-Slim ( EMW Publishing , 2014 , Article)In this paper, we derive a new geometrical blind bend scattering model for vehicle-to- infrastructure (V2I) communications. The proposed model takes into account single-bounce and double- bounce scattering stemming from ... -
Design and implementation of credit-based resource allocation protocol for DSA systems
Hamdi, Rami; Ghorbel, Mehdi Ben; Hamdaoui, Bechir; Guizani, Mohsen ( IEEE Computer Society , 2014 , Conference Paper)This paper designs, implements, and evaluates an efficient dynamic spectrum access (DSA) protocol for cognitive radio networks. The proposed protocol relies on the concept of credit value to allocate resources among users ... -
Design and implementation of distributed dynamic spectrum allocation protocol
Hamdi, Rami; Ghorbel, Mehdi Ben; Hamdaoui, Bechir; Guizani, Mohsen ( IEEE Computer Society , 2014 , Conference Paper)In this paper, we design, implement, and evaluate a resource allocation protocol for distributed dynamic spectrum access (DSA). This protocol, based on learning techniques, enables users to locate and exploit unused spectrum ... -
Distributed dynamic spectrum access with adaptive power allocation: Energy efficiency and cross-layer awareness
Ben Ghorbel, Mahdi; Hamdaoui, Bechir; Hamdi, Rami; Guizani, Mohsen; NoroozOliaee, MohammadJavad ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)This paper proposes energy and cross-layer aware resource allocation techniques that allow dynamic spectrum access users, by means of learning algorithms, to locate and exploit unused spectrum opportunities effectively. ... -
Federated Learning over Energy Harvesting Wireless Networks
Hamdi, Rami; Chen, Mingzhe; Ben Said, Ahmed; Qaraqe, Marwa; Poor, H. Vincent ( Institute of Electrical and Electronics Engineers Inc. , 2022 , Article)In this article, the deployment of federated learning (FL) is investigated in an energy harvesting wireless network in which the base stations (BSs) employs massive multiple-input-multiple-output (MIMO) to serve a set of ... -
Hierarchical Federated Learning over HetNets enabled by Wireless Energy Transfer
