Optimal Policies of Advanced Sleep Modes for Energy-Efficient 5G networks
Fatma Ezzahra Salem, Tijani Chahed, Eitan Altman +2
We study in this paper optimal control strategy for Advanced Sleep Modes (ASM) in 5G networks. ASM correspond to different levels of sleep modes ranging from deactivation of some c…
A Two Phase Investment Game for Competitive Opinion Dynamics in Social Networks
Swapnil Dhamal, Walid Ben-Ameur, Tijani Chahed +1
We propose a setting for two-phase opinion dynamics in social networks, where a node's final opinion in the first phase acts as its initial biased opinion in the second phase. In t…
A Stochastic Game Framework for Analyzing Computational Investment Strategies in Distributed Computing
Swapnil Dhamal, Walid Ben-Ameur, Tijani Chahed +3
We study a stochastic game framework with dynamic set of players, for modeling and analyzing their computational investment strategies in distributed computing. Players obtain a ce…
Optimal Multiphase Investment Strategies for Influencing Opinions in a Social Network
Swapnil Dhamal, Walid Ben-Ameur, Tijani Chahed +1
We study the problem of optimally investing in nodes of a social network in a competitive setting, where two camps aim to maximize adoption of their opinions by the population. In…
A New Alternative for Traffic Hotspot Localization in Wireless Networks Using O&M Metrics
Aymen Jaziri, Ridha Nasri, Tijani Chahed
In recent years, there has been an increasing awareness to traffic localization techniques driven by the problematic of hotspot offloading solutions, the emergence of heterogeneous…
