A Hybrid RF-VLC System for Energy Efficient Wireless Access
Abdallah Khreishah, Sihua Shao, Ammar Gharaibeh +3
In this paper, we propose a new paradigm in designing and realizing energy efficient wireless indoor access networks, namely, a hybrid system enabled by traditional RF access, such…
Hierarchical Capacity Provisioning for Fog Computing
Abbas Kiani, Nirwan Ansari, Abdallah Khreishah
The concept of fog computing is centered around providing computation resources at the edge of network, thereby reducing the latency and improving the quality of service. However,…
Joint Caching, Routing, and Channel Assignment for Collaborative Small-Cell Cellular Networks
Abdallah Khreishah, Jacob Chakareski, Ammar Gharaibeh
We consider joint caching, routing, and channel assignment for video delivery over coordinated small-cell cellular systems of the future Internet. We formulate the problem of maxim…
Delay Analysis of Hybrid WiFi-LiFi System
Sihua Shao, Abdallah Khreishah, Moussa Ayyash
Heterogeneous wireless networks are capable of effectively leveraging different access technologies to provide a wide variety of coverage areas. In this paper, the coexistence of W…
Joint Link Scheduling and Brightness Control for Greening VLC-based Indoor Access Networks
Sihua Shao, Abdallah Khreishah, Issa Khalil
Demands for broadband wireless access services is expected to outstrip the spectrum capacity in the near-term - "spectrum crunch". Deploying additional femotocells to address this…
A provably efficient online collaborative caching algorithm for multicell-coordinated systems
Ammar Gharaibeh, Abdallah Khreishah, Bo Ji +1
Caching at the base stations brings the contents closer to the users, reduces the traffic through the backhaul links, and reduces the delay experienced by the cellular users. The c…
Design of a visible-light-communication enhanced WiFi system
Sihua Shao, Abdallah Khreishah, Moussa Ayyash +5
Visible light communication (VLC) has wide unlicensed bandwidth, enables communication in radio frequency (RF) sensitive environments, realizes energy-efficient data transmission,…
Asymptotically-Optimal Incentive-Based En-Route Caching Scheme
Ammar Gharaibeh, Abdallah Khreishah, Issa Khalil +1
Content caching at intermediate nodes is a very effective way to optimize the operations of Computer networks, so that future requests can be served without going back to the origi…
