	abstract = {Performance of the Adaptive RED scheme is susceptible to bursty web traffic. A parallel queue structure was proposed earlier to address this problem, where real time connections (such as web and UDP) and non-real time connections (such as FTP) are served in two different queues with droptail and Adaptive RED policies, respectively. In this paper a modified Adaptive RED scheme is proposed for the second queue to improve the goodput of non-real time connections. In this scheme the queue length thresholds for the Adaptive RED are dynamically determined by the average droppping probability. Simulation shows that the packet dropping probability of the Adaptive RED queue stays within a desired small region. The stability of the queue length variation under this policy is proved under mild conditions.},

	abstract = {The performance of real-time applications such as video and voice streams relies on packet delay jitter. Large delay jitter causes buffer overflow or underflow at the receiver end and the user encounters interrupt. The delay jitter is mainly due to the perturbation of background traffic in the bottleneck router. Fulton and Li (1998) provide an analytical approximation for the first-order and second-order statistics of delay jitter. However, their analysis is based on a Markovian model of the background traffic, which is not quite suitable for Internet traffic and requires lots of computational effort. We propose an efficient method to predict the jitter variance of a CBR (constant-bit-rate) connection based on the wavelet model of the background traffic. The wavelet analysis extracts the statistical properties of background traffic and the analysis result can be used to predict an upper bound for the jitter variance of the CBR connection.},

	abstract = {Mobile Ad-hoc NETworks (MANETs) are characterized by bandwidth constrained links, multiple hops, varying link qualities and highly dynamic topologies. In this paper, we evaluate the performance and analyze the traffic of a mobile ad-hoc network in a realistic setting. Using simulation, we provide results of performance evaluation in terms of various metrics. We study performance with scenarios of different propagation matrices, different traffic mixes, and different routing protocols (DSDV, DSR, AODV). The results show that in most cases, the performance is sensitive to the routing protocol, path loss, and traffic characteristics. This provides rationale and insight for choosing the right protocols to provide quality of service in terms of different metrics in different environments. Also, we find that in a MANET, we obtain long-range dependency traffic regardless of source file size distribution. This discovery will help in providing methodology to tackle the network dimensioning problem in ad hoc networks.},

In this paper a parallel virtual queue structure is proposed for active queue management at the bottleneck router. Real time connections such as web and UDP, and non-real time connections such as FTP are served in two different virtual queues with drop-tail and Adaptive RED policies, respectively. Both queues share the same physical buffer memory. Simulation shows that file delivery for the web traffic is greatly improved due to shorter packet delay and lower packet loss rate, and that the queue length variation for the FTP traffic is small. To improve the goodput of the non-real time connections, a modified Adaptive RED scheme with dynamic queue length thresholds is also proposed. This scheme is able to keep the packet dropping probability within a desired small region. Stability of the queue length under this scheme is studied through analysis and numerical computation.},

	abstract = {In this paper, an open-loop multilevel ON/OFF modelis proposed to capture the multifractal behavior of the HTTPtraffic on the Internet. It is assumed that the life time of aTCP session and the active time of a burst within a TCP session have a heavy-tail type distribution. The aggregatetraffic of this model is shown to be multifractal. We analyze itssecond and higher order statistics by the wavelet analysis anddevelop a simple method to estimate the model parameters from areal Internet trace. We show that real and synthesized trafficproduce the same Logscale Diagram with accuracy, for properselection of the model parameter. Finally, we compare using theNS-2 simulator the queueing behavior of FIFO queues fed by realand synthetic traffic demands.},
