DRL-Based RAT Selection in a Hybrid Vehicular Communication Network
Badreddine Yacine Yacheur, Toufik Ahmed, Mohamed Mosbah
Cooperative intelligent transport systems rely on a set of Vehicle-to-Everything (V2X) applications to enhance road safety. Emerging new V2X applications like Advanced Driver Assis…
Network Services Anomalies in NFV: Survey, Taxonomy, and Verification Methods
Moubarak Zoure, Toufik Ahmed, Laurent Réveillère
Network Function Virtualization (NFV) has emerged as a disruptive networking architecture whose galloping evolution is prompting enterprises to outsource network functions to the c…
QoE assessment for SVC streaming in ENVISION
Abbas Bradai, Toufik Ahmed, Samir Medjiah
Scalable video coding has drawn great interest in content delivery in many multimedia services thanks to its capability to handle terminal heterogeneity and network conditions vari…
Differenciated Bandwidth Allocation in P2P Layered Streaming
Abbas Bradai, Toufik Ahmed
There is an increasing demand for P2P streaming in particular for layered video. In this category of applications, the stream is composed of hierarchically encoded sub-streams laye…
An efficient playout smoothing mechanism for layered streaming in P2P networks
Abbas Bradai, Ubaid Abbasi, Raul Landa +1
Layered video streaming in peer-to-peer (P2P) networks has drawn great interest, since it can not only accommodate large numbers of users, but also handle peer heterogeneity. Howev…
On the Optimal Scheduling in Pull-based Real-Time P2P Streaming Systems: Layered and Non-Layered Streaming
Abbas Bradai, Toufik Ahmed
During the last decade, we witnessed a rapid growth in deployment of pull-based P2P streaming applications. In these applications, each node selects some other nodes as its neighbo…
Streaming multimedia over WMSNs: an online multipath routing protocol
Samir Medjiah, Toufik Ahmed, Abolghasem Hamid Asgari
Routing is a challenge to Wireless Multimedia Sensor Networks (WMSNs) for supporting multimedia applications due to nodes' energy constraints and computational capabilities, and th…
GEAMS: a Greedy Energy-Aware Multipath Stream-based Routing Protocol for WMSNs
Samir Medjiah, Toufik Ahmed, Francine Krief
Because sensor nodes operate on power limited batteries, sensor functionalities have to be designed carefully. In particular, designing energy-efficient packet forwarding is import…
Orion Routing Protocol for Delay-Tolerant Networks
Samir Medjiah, Toufik Ahmed
In this paper, we address the problem of efficient routing in delay tolerant network. We propose a new routing protocol dubbed as ORION. In ORION, only a single copy of a data pack…
AGEM: Adaptive Greedy-Compass Energy-aware Multipath Routing Protocol for WMSNs
Samir Medjiah, Toufik Ahmed, Francine Krief
This paper presents an Adaptive Greedy-compass Energy-aware Multipath protocol (AGEM), a novel routing protocol for wireless multimedia sensors networks (WMSNs). AGEM uses sensors…
Architecture for Cooperative Prefetching in P2P Video-on- Demand System
Ubaid Abbasi, Toufik Ahmed
Most P2P VoD schemes focused on service architectures and overlays optimization without considering segments rarity and the performance of prefetching strategies. As a result, they…
