Abstract
The Internet of Video Things (IoVT) is expanding rapidly, encompassing applications such as surveillance and remote monitoring. However, efficiently transmitting video data in IoVT poses unique challenges due to resource constraints. Constrained Application Protocol (CoAP) is known as a lightweight protocol, suited for restricted environments. This study examines two CoAP extension methods for multimedia transmission in IoVT: Block-Wise CoAP (BW-CoAP) and Robust Transmission-Enabled CoAP (RT-CoAP), as outlined in RFC 7959 and RFC 9177. RT-CoAP, a recent extension of CoAP, has not been evaluated in previous research. In this study, Raspberry Pi 4 devices with camera modules are used as IoVT nodes, while a computer acts as the sink node to assess CoAP’s real-world performance in video transmission. BW-CoAP and RT-CoAP are compared based on throughput, Round-Trip Time (RTT), per-packet latency, overhead ratio, Segment Download Time (SDT) for H264, Frame Download Time (FDT) for Motion Joint Photographic Experts Group (MJPEG), and energy cost. The results show that RT-CoAP offers better throughput, FDT, SDT, overhead, and energy efficiency, while BW-CoAP excels in RTT and latency, making both protocols suitable for different IoVT and IoT scenarios.
