In this paper, we study the adversarial multi armed bandit problem and present a generally implementable efficient bandit arm selection structure. Since we do not have any statistical assumptions on the bandit arm losses, the results in the paper are guaranteed to hold in an individual sequence manner. The introduced framework is able to achieve the optimal regret bounds by employing general weight...
In the last few years, the concept of network virtualization has gained a lot of attention both from industry and research projects. This paper evaluates the potential of network virtualization from an operator’s perspective, with the short-term goal of optimizing service delivery and rollout, and on a longer term as an enabler of technology integration and migration. Based on possible scenarios for...
The proper adjustment of sleep time in idle mode (a.k.a. DRX-Discontinuous Reception in 3GPP specifications) is critical for mobile device (MD) operation in cellular wireless systems. The dynamic radio environment due to transmission impairments and mobility renders this requirement a nontrivial challenge. Moreover, this issue is aggravated in heterogeneous wireless networks where MDs have to change...
The explosion of mobile multimedia and Internet-of-things (IoT) services implies strong requirements for seamless switching among various types of networks. Thus, to offer true ubiquitous Internet connection, a Fixed and Mobile Converged (FMC) network architecture is essential for the future 5G network. Such a convergent network can not only improve the utilization of network resources, but also inspire...
In this work, we first analyze the accuracy of different energy detector models in approximating the exact solution in AWGN. These models motivate us to develop approximation analysis to address energy detection for fading channels. Our analysis develops approximation that has almost the same performance as the exact solution in Rayleigh channels. Our new model is simple enough to derive the relationship...
This paper describes the ROMEO architecture for live 3D multi-view video delivery over peer-to-peer networks. The scope of the European founded Integration Project ROMEO encompasses addressing the challenges of live multiview video delivery over heterogeneous networks (WiFi, LTE, DVB, etc.) and diverse user equipment (mobile, portable, fixed). In order to achieve seamless uninterrupted 3D video delivery...
