In this paper, we propose a Cross-Layer Stream Control Transmission Protocol (CL-SCTP), which supports multi-streaming and partial reliability for real-time transmissions in IEEE 802.11 wireless networks. In the application layer, we design a Screening Overdue MEssages (SOME) algorithm to leave out transmissions of probable overdue messages. An overdue message refers to a message exceeding its delay budget before the message can be transmitted in the transport layer. Then in the MAC layer, we

A retransmitted frame from the upper layer makes the same frame entering the MAC layer earlier a redundant frame. We discuss our scheme in detail and perform simulations for both random losses and burst losses. Simulation results show our scheme performs better than Cross-Layer Forwarding Prediction Scheduling (CL-FPS), partially reliable SCTP (PR-SCTP), and SCTP in terms of efficient delivery ratio, average goodput, average end-to-end delay, and representative video metrics including Peak Signal to Noise Ratio (PSNR), Structural Similarity (SSIM), and Video Quality Metric (VQM). INDEX TERMS SCTP, multi-streaming, partially reliable, scheduling.
