Congestion control has become a research focus with the development of network communication technology. Random early detection (RED) for queue management techniques is the most effective method. However, RED is particularly sensitive to the traffic load and the parameters of the scheme itself. When the traffic load is low, the bandwidth is underutilized, whereas when the traffic load is high, the...
This letter presents a Flow-Level Extension to OMNeT++ (FLEO) that allows a discrete event simulator to operate on flows of traffic, and so simulate larger networks for longer periods of time for a given set of computation and memory resources compared with packet-based simulation. FLEO simulations of link utilization are accurate to within 0.2% of a packet-based simulation, yet run 30 to 90 times...
According to different priority based services, IEEE 802.16e WiMAX standard classifies packets as UGS, RTPS, eRTPS, nRTPS, BE. The standard treats all packets generated while browsing the internet as delay tolerant packets and classifies them as Best Effort (BE) packets. This includes BE packets generated while browsing secure websites. However, secure transactions are governed by time constraints...
