The Internet is primarily used for content retrieval and information access. However today's IP networks were built to interconnect fixed computing nodes (terminals, servers, etc.), in which communications are based on the node's IP addresses. Such discrepancy causes inefficiencies in networks as well as in application designs. Information-Centric Networking (ICN) has recently attracted research attention and is considered as a promising paradigm for the future Internet architecture, which decouples content from hosts at the network layer, and retrieves a content object by its name (identifier), instead of its storage location (host IP address) in order to address IP network's limitations. However, ICN systems face scalability and efficiency challenges in global deployments. In this talk, we propose a scalable name resolution and routing framework, called Scalable Multi-level Virtual Distributed Hash Table (SMVDHT). SMVDHT uses a combination of name aggregation and multi-level virtual DHTs to achieve scalability. A novel aggregation scheme is proposed to reduce the size and update overhead of name resolution tables. We also design the new protocols to efficiently resolve the aggregated names and route a request to the closest available copy of content.

If time permits, I'll also give an overview of our ongoing and previous projects including video delivery over heterogeneous networks, MIMO cooperative and cognitive networking, and wireless mesh and mobile ad hoc networks.
