  • McGregor, Anthony James (IARIA, 2011)
    Simulation of the Internet has long been understood to be very challenging mostly because of its scale, diversity and the lack of detailed knowledge of many of its components. However, two recent developments (macroscopic ...
  • Neal, Braden; Hunkin, Paul; McGregor, Anthony James (European Association for Computer Graphics, 2011)
    Display walls made from multiple monitors are often used when very high resolution images are required. To utilise a display wall, rendering information must be sent to each computer that the monitors are connect to. The ...
  • Phillips, Caleb; Raynel, Scott McKenzie; Curtis, James; Bartels, Samuel James; Sicker, Douglas; Grunwald, Dirk; McGregor, Anthony James (Springer, 2011)
    In this paper we make use of a large set of measurements from a production wireless network in rural New Zealand to analyze the performance of 28 path loss prediction models, published over the course of 60 years. We propose ...
  • Raynel, Scott McKenzie; McGregor, Anthony James (ACM, 2011)
    The negative performance impact of the presence of hidden terminals in wireless networks has been well know for decades. Despite much research in the area, many deployed networks continue to suffer a performance penalty ...
  • McGregor, Anthony James; Alcock, Shane; Karrenberg, Daniel (2010)
    This paper describes datasets that will shortly be made available to the research community through an Internet measurement data repository operated by the RIPE NCC. The datasets include measurements collected by RIPE NCC ...
  • Hunkin, Paul; McGregor, Anthony James (IEEE, 2010)
    Object migration in wireless sensor networks has the potential to reduce energy consumption for a wireless sensor network mesh. Automated migration reduces the need for the programmer to perform manual static analysis to ...
  • Raynel, Scott McKenzie; McGregor, Anthony James; Jorgensen, Murray A. (IEEE Press, 2009)
    Low power devices such as common wireless router platforms are not capable of performing reliable full packet capture due to resource constraints. In order for such devices to be used to perform link-level measurement on ...
  • Jansen, Samuel Thomas; McGregor, Anthony James (John Wiley & Sons, Ltd., 2007)
    Many existing systems are written in C and are not re-entrant or thread safe. Sometimes these systems are required in a context for which they were not first designed, possibly meaning they now need to be re-entrant. This ...
  • Jansen, Samuel Thomas; McGregor, Anthony James (IEEE Press, Piscataway, NJ, USA, 2007)
    The TCP models in ns-2 have been validated and are widely used in network research. They are however not aimed at producing results consistent with a TCP implementation, they are rather designed to be a general model for ...
  • Jansen, Sam; McGregor, Anthony James (IEEE, 2006)
    Much current simulation of TCP makes use of simplified models of TCP, which is a large and complex protocol with many variations possible between implementations. We use direct execution of real world network stacks in the ...
  • Jansen, Sam; McGregor, Anthony James (ACM, 2005)
    Network simulation is used widely in network research to test new protocols, modifications to existing protocols and new ideas. The tool used in many cases is ns-2. The nature of the ns-2 protocols means that they are often ...
  • McGregor, Anthony James (IEEE Computer Society, 2002)
    Network measurement stands at an intersection in the development of the science. We explore possible futures for the area and propose some guidelines for the development of stronger measurement techniques. The paper concludes ...
  • Pearson, Murray W.; Armstrong, Dean Andrew; McGregor, Anthony James (IEEE, 2002)
    Teaching computer systems, including computer architecture, assembly language programming and operating system implementation, is a challenging occupation. At the University of Waikato this is made doubly true because we ...
  • Luckie, Matthew John; McGregor, Anthony James; Braun, Hans-Werner (ACM, 2001)
    Packet probing is an important Internet measurement technique, supporting the investigation of packet delay, path, and loss. Current packet probing techniques use Internet Protocols such as the Internet Control Message ...
  • McGregor, Anthony James; Pearson, Murray W.; Cleary, John G. (2001)
    As the WWW continues to grow, providing adequate bandwidth to countries remote from the geographic and topological center of the network, such as those in the Asia/Pacific, becomes more and more difficult. To meet the ...
  • McGregor, Anthony James; Braun, Hans-Werner; Brown, Jeff (IEEE Computer Society, 2000)
    The National Laboratory for Applied Network Research is creating a network analysis infrastructure to support network research and engineering of high performance research networks. The NAI includes a passive monitoring ...
  • Cleary, John G.; Graham, Ian; McGregor, Anthony James; Pearson, Murray W.; Siedins, Ilze; Curtis, James; Donnelly, Stephen; Martens, Jed; Martin, Stele (1999)
    Over recent years the size and capacity of the Internet has continued its exponential growth driven by new applications and improving network technology. These changes are particularly significant in the New Zealand context ...
  • Chang, Chung-yi; McGregor, Anthony James; Holmes, Geoffrey (1999)
    Obtaining good performance from WWW proxy caches is critically dependent on the document replacement policy used by the proxy. This paper validates the work of other authors by reproducing their studies of proxy cache ...
  • Cleary, John G.; Graham, Ian; Pearson, Murray W.; McGregor, Anthony James (University of Waikato, Department of Computer Science, 1998)
    The report describes the development of a low-cost ATM monitoring system, hosted by a standard PC. The monitor can be used remotely returning information on ATM traffic flows to a central site. The monitor is interfaces ...
  • McGregor, Anthony James (The University of Waikato, 1997)
    Distributed file systems have become popular because they allow information to be shared be between computers in a natural way. A distributed file system often forms a central building block in a distributed system. Currently ...

  • Wadsworth, Simon Oliver (University of Waikato, 2013)
    Originally cellular networks handled calls and short messages only. Today, this has been extended to handle packet data services. However now the world is moving towards an entirely IP based mobile service based on LTE and ...
  • Löf, Andreas (University of Waikato, 2013)
    Currently, the evaluation of network anomaly detection methods is often not repeatable. It is difficult to ascertain if different implementations of the same methods have the same performance or the relative performance ...
  • Bartels, Samuel James (University of Waikato, 2012)
    Rural New Zealand has poor access to broadband Internet. The CRCnet project at the University of Waikato identified point-to-point wireless technology as an appropriate solution, and built networks for rural communities. ...
  • Luckie, Matthew John (The University of Waikato, 2007)
    Accurately measuring per-hop packet dynamics on an Internet path is difficult. Currently available techniques have many well-known limitations that can make it difficult to accurately measure per-hop packet dynamics. Much ...
