Virtualized Wireless Access in the Green Sustainable Telcommunication Cloud System
This project is primarily focused on virtualizing wireless access network so that multiple operators can share the same physical resources while being able to stay isolated from each other. The basic idea is to allow wireless access points from different operators form a single virtual access point that efficiently manages its available resources. The goal is to exploit the advantages that can be obtained from virtualizing the air interface (i.e., spectrum sharing), protocol virtualization and flow-based virtualization. We consider wireless technologies with long and short ranges, e.g., cellular networks and wireless local area networks. In particular, we investigate on the Long Term Evolution (LTE) and WiFi wireless systems. We will mainly focus on spectrum-based virtualization which is the deepest form of virtualization and is expected to offer more flexibility than protocol- and flow-based ones; it should, however, be noted that spectrum-based virtualizations require flow-based virtualization to isolate the network traffic.
