There are kinds of Internet applications such as VoIP, online gaming and video Conferencing which need quality of service guarantees making the performance analysis critical, and the traffic of such applications usually exhibits the properties of self-similarity and heavy tail. In this paper, we use the generalized Stochastically Bounded Burstiness model to characterize the network traffic with self-similar...
We discuss the dynamic bandwidth allocation schemes in TDMA uplink channel of satellite networks. And a scheme based on max-min fairness is discussed and implemented in Tdma-bod simulator of ns-2. Simulation results show that this scheme can improve the throughput and delay performance and provide better QoS for satellite system. And in future network scenario that including more burst traffic and...
In this paper, we develop a performance analysis framework for wireless mesh network(WMN) based on stochastic network calculus(SNC). Consider that WMN has the characteristic of traffic self-similarity, we use Fractional Brownian Motion(FBM) model to describe the input traffic as a self-similar input process, and we derive statistical traffic envelope and statistical service curve. Then we provide...
The k-ary n-cube which has an n-dimensional grid structure with k nodes in each dimension has been a popular topology for interconnection networks. Analytical models for k-ary n-cubes have been widely reported under the assumptions that the message destinations are uniformly distributed over all network nodes and the message arrivals follow a non-bursty Poisson process. Recent studies have convincingly...
