The Effect of Aggregation on Self-similar Traffic
نویسندگان
چکیده
Traffic aggregation is a basic networking operation that merges separate traffic streams in network switching and cross-connect nodes. This paper discusses the experimental results on a generalized and protocol-independent self-similar traffic generator based on the RPG model of OPNET. The aggregation processes results from merging of multiple traffic traces with various Hurst parameters, where a large set of synthesized self-similar traffic traces have been used. We perform a wavelet-based analysis to investigate the behavior of these aggregated processes. The main conclusion is that the aggregated process still exhibits self-similarity, with Hurst parameter close to the largest one among the underlying separate source traffic.

Research on Aggregation and Propagation of Self-Similar Traffic in Satellite Network
It has already been confirmed that the traffic in high-speed terrestrial network presents self-similarity, but there is little research on self-similarity of traffic in satellite network. Considering time-varying network topology and link status, this paper analyzes the aggregation and propagation of self-similar traffic between nodes in satellite network. Furthermore, a sort of special network...
متن کاملA Simulation Study of the Impact of Switching Systems on Self-similar Properties of Traffic
Recent research has shown that traffic in Ethernet and other networks tends to exhibit properties of self-similarity such as long-range dependence and a high degree of correlation between arrivals. This paper investigates the impact of the switching network on the self-similar properties of the traffic. This simulation study reveals that switching networks tend to reduce the self-similarity of ...

متن کاملModeling Superposition of Many Sources Generating Self Similar Traffic
This paper presents steps towards creating a general model for aggregated traffic streams. We show that fitting the mean, variance and Hurst parameter is insufficient to consistently model a long range dependent traffic stream. A fourth parameter, the “level of aggregation,” is required. We also show that with increased aggregation, the behaviour of a traffic stream tends towards that of a frac...

One of the main challenges in Wireless Sensor Networks is the limited energy of nodes which can cause to reduce the lifetime of nodes and whole network respectively. Transmissions between the nodes consumes most of the nodes' energy so minimization of unnecessary transmissions can led to reduction of energy consumption. Therefor routing protocols designed based on optimal energy consumption are...
