Transport layer design for named data wireless networking

Abstract

The Named Data Networking (NDN) project is emerging as one of the most promising information-centric future Internet architectures. So far, NDN performance in wireless networks has been largely unexplored, especially for what concerns transport mechanisms, which are crucial to ensure reliable and efficient data delivery while accounting for available resources and network dynamics. In this paper, we propose a transport scheme that effects self-regulating Interest rate control (SIRC), reduces the content completion time and more efficiently utilizes channel resources in a wireless ad hoc domain. The presented strategy provides a reliable service that pairs better than most other proposals so far, with the NDN's content multi-homing semantics. A comprehensive evaluation with different traffic loads and propagation settings has been conducted by means of the official NDN simulator, ndnSIM. Our evaluation results show that SIRC outperforms the vanilla NDN approach as well as the often proposed window-based timeout-driven Additive Increase Multiplicative Decrease (AIMD) solutions in wired networks.
