    • Joint resource scheduling and peak power shaving for cloud data centers with distributed Uninterruptible power Supply 

      Alanazi, Sultan; Dabbagh, Mehiar; Hamdaoui, Bechir; Guizani, Mohsen; Zorba, Nizar ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      The grid company enforces high penalties for the peak power demands of cloud data centers. These high penalties result in high electricity bill that can be avoided by relying on the servers' Uninterruptible Power Supply ...
    • Online assignment and placement of cloud task requests with heterogeneous requirements 

      Dabbagh, Mehiar; Hamdaoui, Bechir; Guizani, Mohsen; Rayes, Ammar ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      Managing cloud resources in a way that reduces the consumed energy while also meeting clients demands is a challenging task. In this paper, we propose an energy-aware resource allocation framework that: i) places the ...
    • Reducing data center energy consumption through peak shaving and locked-in energy avoidance 

      Alanazi, Sultan; Dabbagh, Mehiar; Hamdaoui, Bechir; Guizani, Mohsen; Zorba, Nizar ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)
      The grid company enforces high penalties for the peak power demands of cloud data centers. These penalties result in high electricity bills that can be avoided by relying on the servers' uninterruptible power supply (UPS) ...
    • Release-time aware VM placement 

      Dabbagh, Mehiar; Hamdaoui, Bechir; Guizani, Mohsen; Rayes, Ammar ( IEEE , 2014 , Conference Paper)
      Consolidating virtual machines (VMs) on as few physical machines (PMs) as possible so as to turn into sleep as many PMs as possible can make significant energy savings in cloud centers. Although traditional online bin ...
    • Software-defined networking security: Pros and cons 

      Dabbagh, Mehiar; Hamdaoui, Bechir; Guizani, Mohsen; Rayes, Ammar ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      Software-defined networking (SDN) is a new networking paradigm that decouples the forwarding and control planes, traditionally coupled with one another, while adopting a logically centralized architecture aiming to increase ...
    • Toward energy-efficient cloud computing: Prediction, consolidation, and overcommitment 

      Dabbagh, Mehiar; Hamdaoui, Bechir; Guizani, Mohsen; Rayes, Ammar ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      Energy consumption has become a significant concern for cloud service providers due to financial as well as environmental factors. As a result, cloud service providers are seeking innovative ways that allow them to reduce ...
