    • ABSTRACT:
      Our society is becoming increasingly dependent on analyzing huge amounts of data generated in a large variety of ways. Analyzing the “big data” in the cloud requires a tremendous amount of computing and storage resources, and data centers have emerged as the workhorses of the cloud. Large data centers already consist of tens of thousands of servers, and are expected to scale to hundreds of thousands or even millions of servers with total throughputs in the order of several Tbps. Data centers are extremely power-hungry, and already account for over 2% of worldwide energy consumption. Designing data center networks that are both scalable and energy-efficient is very challenging. To address this challenge, the architecture of the data center network has evolved from the conventional multi-layer architecture to modern approaches that marry electronics and optics. This lecture takes a look at this evolution and discusses emerging alternatives.

    • ABSTRACT: Wireless and mobile networks have many advantages as easy deployment, user mobility and provide network access to users regardless to their locations. The most critical problems that arise in these networks are on the resource allocations as the bandwidth is limited, the propagation (multi-path, fading, distortion) and security since communications are transmitted over radio waves. In this lecture I will present several works done to model/Improve Quality of Service in Wireless networks. Three different methods will be presented in this lecture. In the first part a new model based on Markov chains is presented to model the different service classes defined in IEEE 802.16. The second part I will present a new AC that we have defined for IEEE 802.16 and we have evaluated using Stochastic Automata Networks. Finally I will present a stochastic comparison for admission control in wireless networks.

  • Title: SOFTWARIZATION IN MOBILE NETWORKS
    • When: 3 Days Workshop during 6, 7 and 8 June, 2016.
    • Time: 6.00pm-7.30pm each day.
    • Venue: Room 15, Level 03, Building 80 (Swanston Academic Building), 445 Swanston Street, RMIT University, Melbourne
    • Speaker: Dr. Tinku Rasheed, Area Head, Future Networks Department, Create-Net Research, Italy.
    • ABSTRACT: Softwarization is recognized as one of the key features of the upcoming evolution of mobile cellular networks (5G networks) as it drives the paradigm shift of mobile network design and implementation. While softwarization plays this key role for 5G network deployment, management and service provisioning, it is important to note the variety of needs for softwarization in different segments of 5G networks (network segments include the radio access, core network, transport network, network cloud, mobile edge etc) based of the requirement of the specific segments. SDN (Software-defined Networks) and NFV (Network Function Virtualization) are the potential candidates to enable such paradigm shift in the design of 5G Networks. While NFV enables network infrastructure sharing and the “softwarization” of the network functions, SDN enable the decoupling of the control plane and data plane allowing dynamic network programmability. This workshop will provide an overview and analysis of the architectural evolution with the introduction of NFV and SDN in mobile networks. We also introduce different case studies of the impact of such architectural shift on different mobile network segments (radio access, mobile edge computing, mobile backhaul, multi-domain convergence). The workshop will cover the following topics:
      • Day 1: Network Softwarization in 5G: Architectural evolution and NFV/SDN primers for mobile networks
      • Day 2: NFV Management and Orchestration in 5G Networks
      • Day 3: Case Studies of applying NFV/SDN in mobile network segments

    • ABSTRACT: In mid-2017, Google Android is still the dominating mobile OS with a solid 85% of market share. A key-aspect in Android’s success is its openness. Google allows several device manufacturers to use Android. Moreover, Android supports a very dynamic app landscape accessible through the Google Play marketplace as well as third-party markets. The rate of Android success is only matched by the increase in malicious activity targeting Android. Between 2011 and 2012 the malware samples targeting Android has gone up of 1000%. At the end of 2012, Android has crashed another record becoming the top target for malicious code overtaking Microsoft’s Windows operating system. Currently, Android malware is still on the rising despite Google efforts to make its mobile platform more secure. In this talk, I will walk you through some of the important aspects and developments of Android and its security model. Following that, I will cover the most relevant academic efforts that over the years have appeared for enhancing Android security. Finally, I will cover some of the insights I have learned during my stint as CEO of a startup trying to bring to the market a security solution for Android.

It is an emerging and attractive topic in networking and communication communities. In this talk, we will firstly overview the current landscape of this energetic area, and then present the unprecedented challenges in this new domain, and finally discuss the current research directions in the field. We humbly hope this talk will shed light for forthcoming researchers to further explore the uncharted part of this promising land.
  • Title: A Robust Alternative for EM algorithm to handle Outliers-using Integrated Square Distance (L2E)
    • When: 24 October, Wednesday, 12.30 pm – 1.30 pm
    • Venue: RMIT University, Building 80 (Swanston Academic Building, Swanston Street), Level 10, Room 14
    • Speaker: Dr. Umashanger Thayasivam, Associate Professor, Rowan University, New Jersey, USA
    • ABSTRACT:
      Expectation Maximization (EM) with the Maximum Likelihood framework is most popular choice for parameter estimation method for mixture models for univariate and multivariate data. However, the major concern in standard EM algorithm is, it is sensitive to model misspecification and outliers. EM algorithm also requires the number of clusters to be known a priori. In this talk I will discuss a robust data driven alternative based on minimum integrated square distance, namely L2E, which can outperform EM when outliers present, at the same time can also use for model-based clustering for Gaussian Mixture Models (GMM). With the big data era, simple tasks such as data cleaning not easy to handle, hence this L2E become a powerful alternative in such practical situation. I will illustrate the use of L2E through simulations and real data analysis. I will also discuss the robustness properties of our estimators.
