iNAT: Intelligent Naming and Adaptive Transmission

Project goals

The next-generation Internet (NGI) is certain to be different from the current one in several important ways, including the degree of mobility and dynamism of its hosts and services, the degree of integration with the physical environment of sensors and actuators, and the heterogeneity of data transmitted on its links. The goal of the iNAT project is to design, implement, deploy, and evaluate an integrated approach to resource naming, message routing, and adaptive data transmission for this future environment. The deliverables of iNAT include a suite of middleware, algorithms, and protocols, which together solve several hard problems including remote device access (e.g., surveillance cameras), host and service mobility, group communication to dynamic services, audio/video dissemination over heterogeneous networks, and congestion management techniques for the NGI.

More specifically, our goals are:

  1. To develop a naming system for resource discovery in ad-hoc, dynamic and mobile networks without pre-configured support or infrastructure. This will enable self-organizing distributed applications such as camera surveillance networks accessible by mobile users. A specific objective of the naming system is to make it possible to name and gain access to devices and services without knowing their network location, instead describing them via an expressive and descriptive syntax.
  2. A mobility architecture for the NGI that can handle changing network locations for hosts.
  3. To develop a resource management framework to manage congestion and enable adaptive multimedia applications (e.g., video and audio) in the NGI. This framework should empower applications to learn about network conditions and adapt their behavior to current conditions
