The diffserv cognitive network node with Controlled-UDP

The existing cognitive network (CN) nodes do not support Differentiate-Serve (Diffserv) Quality of Service (QoS), and the existing Diffserv QoS scheme has not considered the link capacities between UDP subscribers and TCP subscribers of CN nodes. To solve these problems, a Diffserv CN node and Controlled-UDP (C-UDP) based fluid model are proposed for hybrid traffics' CN. The proposed C-UDP and CN node limit the data rates of UDP subscribers according to their priorities, and allocate the link capacities to different classes of TCP traffics and C-UDP traffics. The dynamic simulation results demonstrate the proposed CN node and C-UDP for the TCP/UDP hybrid traffics for CN to be valid.
