A rate-based streaming protocol for wireless networks
W. K. Chan, S. W. Ng · 2005
Rate Adaptation Protocol (RAP) is a rate-based protocol that has been proposed to provide a non-reliable realtime streaming service over the Internet. It is also TCP friendly, which is crucial for network environments where real-time streams need to coexist with traditional data traffic. In this paper we show that using RAP in a lossy wireless network environment will result in two major problems: explosive increase in transmission rate after link error and possibility of the protocol getting stuck in a freeze mode (i.e. transmission rate no longer adaptive). We propose a number of solutions for these problems and test the performance of the modified protocol by means of extensive simulation.
