Determination of synthetic phenolic antioxidants in cake by HPLC/DAD after mixed micelle-mediated cloud point extraction

Datagram congestion control protocol (dccp) is a transport-layer protocol designing for multimedia applications to transmit congestion-controlled data streams over internet. the major features of dccp protocol include a tcp-friendly rate control (tfrc) mechanism to ensure fair bandwidth sharing with tcp,and a partial payload protection mechanism to retrieve the effective data from error-corrupted packets. in enabling a robust data transmission for dccp flows over wireless networks with the automatic repeat request (arq) capacity,the packetization scheme needs to be fitted to the new dccp features and arq-based transmission scenario. to be more specific,the partial payload protection mechanism can be inefficient owing to mac-layer retransmissions,while varying packet size has an adverse effect on the tcp-friendliness of dccp flows. this paper proposes two main contributions in designing the efficient packetization scheme for dccp flows,namely (1) a dccp protocol enhancement to benefit the partial payload protection mechanism by utilizing the arq retransmissions and then (2) an in-packet segmentation scheme to improve the data goodput while preserving the tcp-friendliness of the dccp flows. the experimental results demonstrate the effectiveness of the proposed scheme based on the results of packet corruption probability and normalized throughput under a variety of network conditions.
