NMRTS: content name-based mobile real-time streaming

摘要

In light of the rapid growth in mobile video traffic and demand for stable video viewing with higher video resolution, we introduce a novel transport protocol for content-centric networking (CCN), named Content Name-Based Mobile Real-Time Streaming (NMRTS). NMRTS utilizes "symbolic interest" for mobile users to receive real-time streaming without sending bursty requests, and the regular interests (which CCN generally uses) to recover lost packets during handover. NMRTS can support seamless handover by adjusting the symbolic interest lifetime and its transmission frequency according to network conditions. Through simulations, we demonstrate that NMRTS reduces the amount of both control message transmission and redundant data traffic, and minimizes data reception delay, compared with the general CCN.
