Research on wireless network testbeds for the Future Internet
Recently, many network testbeds have been developed for wireless networks (e.g., ORBIT, APE, MIT Roofnet, TAPs, WHYNET) for the evaluation of new proposals. Each wireless testbed is targeted on a specific access network such as mesh network or ad-hoc sensor network. Unfortunately, we found that wireless testbeds have a limited spectrum of radio technologies: all the testbeds are exploiting the same wireless access based on IEEE 802.11x protocol, even though cellular networks (e.g. 3G) is popular worldwide and WiMAX is emerging rapidly. To resolve this situation, we set the goal of this project as developing a new wireless testbed, dubbed as Cell-Lab, based on cellular radio access.
Research on interconnection between heterogeneous networks
The architecture design for inter-working between Future Internet and delay tolerant network (DTN) consists of three steps. First, we define inter-working scenarios considering various DTN situations and ubiquity then suggest abstract level inter-working framework. Second, we research on component technologies of future DTN architecture based inter-working framework which we proposed previous step. We will be able to propose some communication protocols such as DTN multicast/anycast protocols. Finally, we study architecture into which these component technologies can be merged.
Research on broadcast/multicast system for the Future Wireless Network
Nowadays, internet traffic is mostly composed of point-to-point service and best-effort traffic. On the other hand, in the future internet where communication and broadcasting are fused together, the transmission of realtime multimedia traffic will be very common. As multimedia traffic will occupy considerable bandwidth, it will be more efficient transmitting one video traffic in an overlapping path in a communication network than transmitting video traffic for each of the viewers that are watching for the same multimedia data(e.g., any television channel) at the same time. We have to use multicast routing for this. The actual problem is the handover processing time and channel switching delay in the case of user's mobility. To minimize this problem, we are to research about the method of transmitting the correspond channel traffic in advance in wireless network determining the estimation of user's mobility and channel preference.
Content-Centric Network Architecture and Services for Future Internet
While current Internet architecture is designed based on the host-to-host communication paradigm, real Internet usage shows patterns more like data/content-centric paradigm. In other words, users don't care from whom they get needed data but care the data itself. Due to the inconsistency between Internet design and real usage, there are unnecessary procedures when users try to retrieve desired data. In consequence, it is needed to redesign the Future Internet based on content-centric paradigm to provide rich data/contents to the users in Future Internet. In this project, we will propose new Internet architecture based on data/content-centric paradigm to support rich and convenient data/content services in Future Internet. We'll also propose a pilot service in content-centric network and deploy testbeds for the new architecture and new services.
