  • Takyi, A; Densmore, M; Johnson, D (2016-09)
    Collaborative sensing among secondary users in television white space (cognitive radio) networks can considerably increase the probability of detecting primary or secondary users. In current collaborative sensing schemes, ...
  • Maliwatu, R; Zlobinsky, Natasha; Densmore, M; Johnson, D (2016-09)
    Dynamic Spectrum Access (DSA) provides a new opportunity for last-mile and rural connectivity. However, the nature of DSA and varying environmental conditions means that desired spectrum is not always available. To that ...
  • Zlobinsky, Natasha; Johnson, David (2016-09)
    The concept behind this work is to build mesh net-works in the TVWS band for developing regions to improve internet access opportunities. The purpose is to solve a pertinent problem within the context, namely to find an ...
  • Hadzic, S; Phokeer, A; Johnson, D (IEEE, 2016-10)
    This paper describes a network architecture to provide low cost last mile access and cloud services for local content sharing in a poorly resourced township environment. We describe how ICT solutions are developed in close ...
  • Phokeer, A; Johnson, D; Densmore, M (2016-09)
    The paper describes a measurement study of mobile Internet usage in township communities in South Africa. The idea is to understand usage pattern of mobile data that would motivate the provisioning of a localised cloudlet ...
  • Johnson, David L; Van Stam, G (2016-12)
    Network protocols and applications have mostly been developed in and for a Western context and usually have an embedded set of assumptions about network performance and availability. As a result web-browsing, cloud-based ...
  • Johnson, David; Zlobinsky, Natasha; Lysko, Albert A; Lamola, Magdeline; Hadzic, S; Maliwatu, R; Densmore, M (2016-12)
    TV White Space networks are gaining momentum worldwide as an important addition to the suite of wireless protocols available for connecting de-veloping regions. However, there has been no thorough investigation of scenarios ...
  • Ntuli, N; Abu-Mahfouz, Adnan M (Elsevier, 2016-05)
    Water scarcity and water stress issues have become clear threat to the global population. This makes water management a critical aspect to ensure sustainable water. An efficient water management system requires thousands ...
  • Lamola, MM; Johnson, David; Lysko, Albert A; Zlobisnky, Natasha (http://www.satnac.org.za, 2016-09)
    Dynamic Spectrum Access (DSA) plays a vital role in opportunistic access to spectrum. A key component of DSA is preventing interference to the incumbent (primary) user from the secondary user. We present the results of an ...
  • Burger, Chris (South African Radio League (SARL), 2016-01)
    This Introduction to Amateur Radio is exactly that: The document provides an entry into the wonderful world of amateur radio, specifically for would-be radio amateurs. South Africa complies with CEPT T/R 61-01, the European ...
  • Akpakwu, GA; Hancke, GP; Silva, BJ; Abu-Mahfouz, Adnan (IEEE, 2016-07)
    The concept of data distribution within cluster of sensor nodes to the source sink has resulted to intense research in Wireless Sensor Networks (WSNs). In this paper, in order to determine the scheduling length of packet ...
  • Louw, J; Niezen, G; Ramotsoela, TD; Abu-Mahfouz, Adnan (IEEE, 2016-12)
    Wireless sensor networks (WSNs) have become increasingly popular in many applications across a broad range of fields. Securing WSNs poses unique challenges mainly due to their resource constraints. Traditional public key ...
  • Dorasamy, Kribashnee; Webb-Ray, Leandra; Tapamo, J-R (Springer, 2016-12)
    Overcoming small inter-class variation when fingerprints have missing singular points (SPs) is one of the current challenges faced in fingerprint classification, since class information is scarce. Grouping the orientation ...
  • Phokeer, A; Aina, A; Johnson, David (African Network Information Centre (AFRINIC), 2016-12)
    The DNS, as one of the oldest components of the modern Internet, has been studied multiple times. It is a known fact that operational issues such as mis-configured name servers affect the responsiveness of the DNS service ...
  • Dzivhani, Mulalo; Soganile, N; Bembe, Mncedisi (www.satnac.org.za, 2016-09)
    Long Term Evolution Advanced (LTE-Advanced) networks enables the use of new and wider radio frequency spectrum and other new technologies that facilitates high data rates and lower latency. Furthermore, LTE-Advanced adopt ...
  • Nkosi, Mpho C; Lysko, Albert A; Engelbrencht, A; Nyandeni, Thulani (http://www.satnac.org.za, 2016-09)
    With the growing adoption of programmable networks, the protection and restoration schemes for optical networks needs to be thoroughly looked into so as to guarantee efficiency and resiliency for the new Software Defined ...
  • Ramoroka, MT; Masonta, Moshe T; Kliks, A (Springer, 2015-12)
    The role of cheap and easy access to various telecommunication facilities is crucial for further community development. Such an observation is of particular importance for the developing countries all over the world since ...
  • Mauwa, H; Bagula, A; Zennaro, M; Pietrosemoli, E; Lysko, Albert; Brown, TX (International Telecommunication Union (ITU), 2016-11)
    Access to the television white space by white space devices comes with a major technical challenge: white space devices can potentially interfere with existing television signals. Two methods have been suggested in the ...
  • Fisher, R; Ledwaba, Lehlogonolo; Hancke, G; Kruger, Carel (MDPI, 2015-03)
    The concept of the Internet of Things is rapidly becoming a reality, with many applications being deployed within industrial and consumer sectors. At the ‘thing’ level—devices and inter-device network communication—the ...
  • Abu-Mahfouz, Adnan M; Hamama, Y; Page, Philip R; Djouani, K; Kurien, A (Elsevier, 2016-08)
    South Africa is a water scarce country with limited water resources and steadily growing water demand. Unacceptably high water losses and non-revenue water threaten our water resource security as well as the financial ...
