Agile Uncertainty Assessment for Benefit Points and Story Points
IEEE Software 36, no. 4 (2019): 50-62.Status: Published
Agile Uncertainty Assessment for Benefit Points and Story Points
Estimates are inherently uncertain, and it’s fair to expect that business value estimates are even more so. By making this uncertainty explicit, you can manage and monitor your agile project according to upper and lower margins of uncertainty. The trick is to instantiate benefit points and story points with values reflecting various scenarios.

Relations between Project Size, Agile Practices and Successful Software Development

Relations between Project Size, Agile Practices and Successful Software Development
The use of agile methods in the execution of large-scale software development is increasing. To find out more about the effect of this on project performance, information was collected about 196 Norwegian IT-projects. Increased project size was associated with decreased project performance for both agile and non-agile projects, but the projects using agile methods had better performance than the non-agile projects for all examined project size categories. Flexible scope, frequent deliveries to production, a high degree of requirement changes and more competent providers are candidates to explain the better performance of agile projects.

Artificial Intelligence Empowered Mobile Sensing for Human Flow Detection

Artificial Intelligence Empowered Mobile Sensing for Human Flow Detection
Intelligent human detection based on WiFi is a technique that has recently attracted a significant amount of interest from research communities. The use of ubiquitous WiFi to detect the number of queuing persons can facilitate dynamic planning and appropriate service provisioning. In this article, we propose HFD, one of the first schemes to leverage WiFi signals to estimate the number of queuing persons by employing classifiers from machine learning in a device-free manner. In the proposed HFD scheme, we first utilize the sliding window method to filter and remove the outliers. We extract two characteristics, skewness and kurtosis, as the identification features. Then, we use the support vector machine (SVM) to classify these two features to estimate the number of people in the current queue. Finally, we combine our scheme with the latest Fresnel Zone model theory to determine whether someone is in or out, and thus dynamically adjust the detected value. We implement a proof-of-concept prototype upon commercial WiFi devices and evaluate it in both conference room and corridor scenarios. The experimental results show that the accuracy of our proposed HFD detection can be maintained at about 90 percent with high robustness.

NorNet at the University of Sydney: From Simulations to Real-World Internet Measurements for Multi-Path Transport Research

NorNet at the University of Sydney: From Simulations to Real-World Internet Measurements for Multi-Path Transport Research
A large fraction of the communication in the Internet is handled by the Transmission Control Protocol (TCP). Since the first deployments of this protocol more than 30 years ago, the spectrum of applications as well as the structure of the network have developed at a fast pace. For example, today's network devices, like smartphones and laptops – i.e.\ particularly many devices in the area of mobile computing – frequently have an interesting property: the existence of multiple IP addresses (IPv4 and/or IPv6). The addresses may even change due to mobility. This property, denoted as multi-homing, can be utilised for multi-path transport, i.e. the simultaneous usage of multiple paths in the network to improve performance. Multi-path transport is a hot topic in the Internet Engineering Task Force (IETF), which is the standardisation organisation for the Internet.
This talk provides an overview of the work in the areas of multi-homing and multi-path transport, with focus on the area of the protocols TCP and Stream Control Transmission Protocol (SCTP) with their experimental extensions Multi-Path TCP (MPTCP) and Concurrent Multi-Path Transfer for SCTP (CMT-SCTP). It particularly shows the sequence of research and selected results, beginning from a simple simulation model, via lab setups and small Internet scenarios, up to the large-scale, international testbed project NorNet. NorNet, and particularly its landline network part NorNet Core, is furthermore described in some detail. Based on NorNet, it is finally possible to validate simulation results in real-world, multi-homed networks, in order to provide valuable input to the ongoing IETF standardisation processes of MPTCP and CMT-SCTP. Particularly, it will also show how the NorNet testbed can be utilised for research at the University of Sydney.

Mobile Edge as Part of the Multi-Cloud Ecosystem: A Performance Study

Mobile Edge as Part of the Multi-Cloud Ecosystem: A Performance Study
Cloud computing has revolutionized the way of application usage and deployment: applications run cost-effectively in remote data centers. With the increasing need for mobility and micro-services, particularly with the upcoming 5G mobile broadband networks, there is also a strong demand for mobile edge computing (MEC): applications run in small cloud systems in close proximity to the user, in order to minimize latencies. Both cloud and MEC have their advantages and disadvantages. Combining the two approaches in a unified multi-cloud, consisting of both traditional cloud services provisioned over heterogeneous cloud platforms and MEC systems, has the potential of obtaining the best out of both worlds. However, a comprehensive study is needed to evaluate the performance gains and the overheads involved for real-world cloud applications. In this paper, we introduce a baseline performance evaluation in order to identify the fallacies and pitfalls of combining multiple cloud systems and MEC into a unified MEC-multi-cloud platform. For this purpose, we analyze the basic, application-independent performance metrics of average round-trip time (RTT) and average application payload throughput in a setup consisting of two private and one public cloud systems. This baseline performance analysis confirms the feasibility of MEC-multi-cloud, and provides guidelines for designing an autonomic resource provisioning solutions, in terms of an extension proposed to our existing Melodic middleware platform for multi-cloud applications.

A Real-Time Video Streaming System over IPv6+MPTCP Technology

A Real-Time Video Streaming System over IPv6+MPTCP Technology
Today, a steadily increasing number of users not just passively consumes Internet content, but also creates and publishes content. Users publish text, photos and videos. With the availability of 5G high-speed, low-latency mobile broadband networks, also real-time video streaming will be possible. We believe this will become a very popular application in the coming years. But the more popular a service is, the higher the need for resilience. In this paper, we introduce our work-in-progress live video streaming platform for future mobile edge computing scenarios, which makes use of MPTCP+IPv6 to support multi-homing for resilience, and multi-path transport for load balancing. As a proof of concept, we show that the platform is (1) compatible with IPv6, (2) utilizes load balancing when possible, and (3) provides robustness by network redundancy.
