Online VNF Chaining and Predictive Scheduling: Optimality and Trade-offs
Xi Huang, Simeng Bian, Xin Gao +4
For NFV systems, the key design space includes the function chaining for network requests and resource scheduling for servers. The problem is challenging since NFV systems usually…
Service Chain Composition with Failures in NFV Systems: A Game-Theoretic Perspective
Simeng Bian, Xi Huang, Ziyu Shao +2
For state-of-the-art network function virtualization (NFV) systems, it remains a key challenge to conduct effective service chain composition for different network services (NSs) w…
PORA: Predictive Offloading and Resource Allocation in Dynamic Fog Computing Systems
Xin Gao, Xi Huang, Simeng Bian +2
In multi-tiered fog computing systems, to accelerate the processing of computation-intensive tasks for real-time IoT applications, resource-limited IoT devices can offload part of…
Green Offloading in Fog-Assisted IoT Systems: An Online Perspective Integrating Learning and Control
Xin Gao, Xi Huang, Ziyu Shao +1
In fog-assisted IoT systems, it is a common practice to offload tasks from IoT devices to their nearby fog nodes to reduce task processing latencies and energy consumptions. Howeve…
History-Aware Online Cache Placement in Fog-Assisted IoT Systems: An Integration of Learning and Control
Xin Gao, Xi Huang, Yinxu Tang +2
In Fog-assisted IoT systems, it is a common practice to cache popular content at the network edge to achieve high quality of service. Due to uncertainties in practice such as unkno…
Online User-AP Association with Predictive Scheduling in Wireless Caching Networks
Xi Huang, Shuang Zhao, Xin Gao +3
For wireless caching networks, the scheme design for content delivery is non-trivial in the face of the following tradeoff. On one hand, to optimize overall throughput, users can a…
