Recently, the Internet of Things (IoT) has attracted the interest of network researchers all over the world. Multimedia transmission through IoT presents an important challenge owing to nodes diversity. In this paper, adaptive versions of the real-time transport protocol (RTP) and real-time control protocol (RTCP), i.e., IoT-RTP and IoT-RTCP, are proposed. In these versions, the nature of IoT environments, such as transmission channels heterogeneity, sudden change in session size, and different multimedia sources, is considered. The basic idea of the proposed adaptive versions is to divide the large multimedia sessions into simple sessions with awareness of network status. To achieve this target, additional fields are added to the RTP and RTCP headers. These fields work under certain conditions to decrease the network overload. Finally, to test the performance of the proposed IoT-RTP and IoT-RTCP, a simulation environment is constructed using the network simulation package (NS2).The results of intensive simulations proved that the proposed adaptive versions of the multimedia protocols outperform the basic ones in terms of end-to-end delay, delay jitter, number of receiver reports, packet loss, throughput, and energy consumption.
