Prospective cloud management requires sophisticated monitoring capabilities. In this paper, we introduce a novel monitoring framework for cloud-based workflow systems called cWorkload. cWorkload integrates monitoring information from different layers of the cloud architecture. The paper puts its focus on the two-layer monitoring regarding the workflow layer and the PaaS layer. We present the la...

T he interest in wireless communications has grown constantly for the past decades, leading to an enormous number of applications and services embraced by billions of users. In order to meet the increasing demand for mobile Internet access, several high data-rate radio networking technologies have been proposed to offer wide area high-speed wireless communications, eventually replacing fixed (w...

Title of dissertation: CROSS-LAYER ASPECTS OF COGNITIVE WIRELESS NETWORKS Anthony A. Fanous, Doctor of Philosophy, 2013 Dissertation directed by: Professor Anthony Ephremides Department of Electrical and Computer Engineering We study cognitive wireless networks from a cross-layer perspective, where we investigate the effects of the PHY layer parameters and enhancements on the MAC layer performa...

The evolution from wired system to the wireless environment opens a set of challenge for the improvement of the wireless system performances because of many of their weakness compared to wired networks. To achieve this goal, cross layer techniques are used to facilitate the sharing of information between the layers of the OSI model. In some precedent works, the Reverse Cross Layer (RCL) method ...

In the past few decades, the world has witnessed a rapid growth in mobile communication and reaped great benefits from it. Even though the fourth generation (4G) mobile communication system is just being deployed worldwide, proliferating mobile demands call for newer wireless communication technologies with even better performance. Consequently, the fifth generation (5G) system is already emerg...

We study the use of learning for cross-layer optimization of wireless networks. In particular, we incorporate learning in the form of graphical models into our cognitive engine performing network utility maximization task using simulated annealing. Our results show that this learning approach can significantly accelerate the convergence rate of the optimizer, and help in adjusting to changes in...

As the cellular and PCS world collides with wireless LANs and Internet-based packet data, new networking approaches will support the integration of voice and data on the composite infrastructure of cellular base stations and Ethernet-based wireless access points. This article highlights some of the past accomplishments and promising research avenues for an important topic in the creation of fut...

Layered architectures are not sufficiently flexible to cope with the dynamics of wireless-dominated next-generation communications. Most existing architectures and approaches depend purely on local information and provide only poor and inaccurate information gathering at the global scale. De-layered or crosslayer architectures may provide a better solution: cross-layering allows interactions be...
