The future of the $51 billion Australian National Broadband Network (NBN) remains unknown, with the Government still to commit to a course of action after the current build phase. Industry representatives have recently voiced their concerns about a potential future sale of the NBN and how this would occur. In response, the Telecommunications Association is hosting a public forum on the future of the NBN on 31 July 2019. Papers in the June 2019 issue of the Journal include discussion on consumer interest in 5G in New Zealand, the history of Australian mail handling and technical papers covering a range of interesting topics.
Papers in the March 2019 issue of the Journal include discussion on the National Broadband Network, technical papers on the Internet, MANET and Cloud security and a fascinating look back at the Eucla Recorder. The history of Australian telecommunications paper covers the Australian Post Office’s involvement in the Apollo 13 emergency and a review of laser developments. In the present day, 8K televisions launch in Australia on 1 April 2019 and in the process move entertainment and telecommunications into the next phase of development.
Two historic technical news items from 1970 covering the Australian Post Office’s involvement in the Apollo 13 emergency and a non-theoretical review of laser developments.
Two historic papers from 1966 detailing the mail handling scene in Australia and the development of the state-of-the-art Sydney Mail Exchange.
This paper provides results from a survey of broadband customers in Australia in November 2017. Overall, we identify that about 30% of existing fixed broadband households would consider switching to a wireless broadband service. We also note the future rollout of 5G wireless service and the resultant market positioning of telcos, which may support further positive perceptions of wireless broadband.
This study proposes PEGADyn – a hybrid version of PEGASIS and Dynamic State algorithm for a new energy-efficient routing protocol in ad hoc networks. PEGADyn creates a virtual grid classification of nodes based on current location, followed by a cluster formation of nodes in each virtual grid created. The use of cluster heads (CHs) and designated cluster heads (dCHs) -- selected based on energy levels -- limits communication overheads among nodes, reducing the energy expended and increasing the network lifetime.
A large number of cellular operators in an area causes high interference effects. One problem is high received total wideband power (RTWP). To solve this problem, an RF band-pass filter device can be implemented on a UMTS system. QoS measurements with the Huawei M2000 application and Drive Test were carried out, with the analysis capturing RTWP, Circuit-Switched access rate, Packet-Switched access rate, and Received Signal Code Power (RSCP) value. The results indicate an increase in QoS.
Despite a considerable increase in Internet capacity, regional congestion is still an issue at certain times of day. We therefore investigate a scheme that allows end-users to selectively exploit a sequence of mini-tunnels along a path from their origin to a chosen destination. Such tunnels can be advertised centrally through a broker, with the cooperation of the Autonomous System (AS) domain operators, similar to a driver choosing to use a toll road to avoid potential congestion.
The gathering of data from household IoT-enabled devices will incur an energy cost and, in this paper, we investigate the impact of different communications technologies and protocols on that cost. As a first step towards energy-efficient design, we have measured the power consumption of several popular wireless interfaces – Bluetooth (Classic and Low Energy), ZigBee, Wi-Fi and 433 MHz module (RF433). We then combine these measurements through the example of a simple domestic stock control application and we show how an energy-efficient communications paradigm can be designed in each case.
This paper proposes a novel approach to compute the probability distribution of cloud security threats based on a Markov chain and Common Vulnerability Scoring System. Moreover, the paper introduces the method to estimate the probability of security attacks. The use of the new security threat model and its computation is demonstrated through their application to estimating the probabilities of cloud threats and types of attacks.
In this paper, we introduce a method that quantifies the amount of traffic over time by the help of a cloud calculation service and vehicular communication. Furthermore, the approach is applicable also in vehicular traffic simulations, which are widely used in research to demonstrate the effects of proposed solutions to traffic problems. The approach is proven by simulations and application of the load calculation in combination with an intelligent route optimization approach by comparing the optimization gain with the calculated traffic load.
The Australian Multi-Technology Mix (MTM) NBN plan includes Fibre to the Node technology and remediating and upgrading the existing Telstra and Optus Hybrid Fibre Coaxial networks. This paper discusses the migration from the MTM NBN to a Fibre to the Curb or ubiquitous Fibre to the Premises (FTTP) NBN.
This paper summarizes results from a survey of the New Zealand mobile market by Venture Insights in October 2018. The survey identified a strong consumer interest in and awareness of 5G, with mobile video a strong driver. Fixed wireless broadband service was also strongly supported, and Ultra-Fast Broadband fixed service is likely to be a strong competitor to fixed wireless broadband.
In Mobile Ad hoc Networks (MANETs) the nodes act as a host as well as a router, thereby forming a self-organizing network that does not rely upon fixed infrastructure, other than gateways to other networks. Security is important for MANETs and trust computation is used to improve collaboration between nodes. This paper proposes an Artificial Immune System-based reputation (AISREP) algorithm to compute trust and thereby provide a resilient reputation mechanism.
In the past two decades digital inequality has come to be understood as a complex, evolving and critical issue, generating demand for more complex measurement tools. The Australian Digital Inclusion Index (ADII), developed in 2015, is a composite index that addresses this demand. This paper describes the development of the ADII, its architecture and the dataset used to populate it.
The rise of Eucla in the late nineteenth-century as a border telegraph station, located on Western Australia’s southern maritime border with South Australia, has been celebrated by Moyal (1984) for the cohesion and resilience of its skilled workforce. This article further explores the Eucla story, offering a vivid snapshot of the community’s preoccupations and challenges at the end of the 19th century through the pages of its monthly newspaper, the Eucla Recorder (1898 – 1900).
