Quality Adaptation of Constrained Application Protocol Multimedia Streaming in Internet of Things [PDF]

Keywords: CoAP, Internet of Things, multimedia, quality adaptation, streaming

In this paper, we present a quality adaptation of constrained application protocol (CoAP) multimedia streaming, which is abbreviated as QACMS, in the Internet of Things (IoT). The QACMS is designed to support reliable and high-quality multimedia streaming in a constrained environment. To achieve this, the QACMS adaptively selects the quality level of multimedia content considering the available bandwidth of the wireless link and decides the bitrate of chunks by adjusting the CoAP observation period. To verify the effectiveness of the QACMS, an experimental simulation is conducted in various simulation scenarios. The results show that the QACMS performs better than the existing CoAP-based streaming in terms of packet loss rate and bandwidth utilization.
