Estimation of Backlog and Delay in OFDM/ TDMA Systems with Traffic Policing Through Network Calculus
In this paper, we firstly propose a policing algorithm based on multifractal traffic modeling, evaluating its performance in comparison to other algorithms. Further, we present an approach based on Network Calculus for estimating quality of service parameters, such as mean queue length (backlog) and delay. We analyze these two parameters for an OFDM/TDMA based simplified […]
An Approach to Support the Interoperability of Intelligent Grouping and Resource Sharing (IGRS) and Universal Plug and Play (UPnP) in Home Network Environment
To achieve interconnection and interoperability among different devices in home network environment, such as TV, PAD, and computer. Several digital home network protocol standards, such as UPnP, Java Intelligent Network Infrastructure (Jini), IGRS, etc, are proposed. But, devices based on these different protocols cannot discover or control each other, so it is very important to […]
The Software-Defined Networking (SDN) paradigm allows networking hardware to be made “malleable” and remotely manageable by the so-called SDN controllers. However, the current SDN landscape is extremely fragmented. Different open and closed source controller frameworks such as Open-Daylight , Ryu , Floodlight , etc. exist. Porting SDN applications from one such platform to another is […]
PMUs play an essential rule in monitoring and control of power network. However, it is not possible to install PMUs at all buses of network, due to economical and technical constrains. Therefore, optimal PMU placement (OPP) is done to obtain full observability of network with minimum number of PMUs and maximum redundancy. On the other […]
A comparison study of joint and sequential multi-layer planning for IP over flexible optical networks
We propose a joint multi-layer planning algorithm for IP over flexible optical networks, and use it, to compare the performance of joint as opposed to sequential multi-layer network planning in terms of spectrum and cost.
Current telecom networks generate massive amounts of monitoring data consisting of observations on network faults, configuration, accounting, performance, and security. Due to the ever increasing degree of complexity of networks, coupled with specific constraints (legal, regulatory, increasing scale of management in heterogeneous networks), the traditional reactive management approaches are increasingly stretched beyond their capabilities. A […]
Sparsity Enhanced Mismatch Model for Robust Intercell Interference Management in Heterogeneous Networks with Doubly-Selective Fading Channels
Transmission over doubly-selective fading (DSF) interference channel often relies on the use of robust precoder due to a lack of accurate channel state information, with performance often depending on the conservativeness of the mismatch model. Previously proposed mismatch models either have been deemed too conservative (deterministic models) or are prone to error due to inaccuracy […]
