Abstract

Wide rural areas are often short of basic communication facilities and suffer from harsh geographic and climatic environments. Wireless networks which offer ease of operation and low maintenance cost appears to be a fast and feasible choice for service operators to install their individual networks. We first propose a refined wireless networking method to foster communication construction in rural areas. A one-pipefour-layer wireless simulation model, called Service Model, is highlighted in the paper to implement the network planning method. The Service Model collects raw data from given rural areas and abstracts these data by flowing them through four technical layers to form the predicted technical wireless network. Thereafter, a software simulation environment, BrwsLi, is coded in freeware Scilab to realize the Service Model for the sake of instantiation. This simulation environment is able to set up a specified rural network by constructing topology for the network on the depicted areas, simulate the network traffic, and evaluate network performance and economic efficiency. The Newcastle region in KwaZulu-Natal of South Africa is chosen as the sample of real-world cases to demonstrate how to practically apply Service Model and present how to operate BrwsLi properly.

He also contributed to Vodafone Australia’s preliminary design of 3G radio access network in the Emerging Technologies Group. He has represented Vodafone Australia in the Vodafone Research Group from where he was spotted and appointed as Adjunct Professor in 2002 at the Department of Computer Science, University of the Western Cape (UWC). He is a key member of the Telkom / Cisco Centre of Excellence in Internet Computing at UWC and a rated researcher by the National Research Fund (NRF, South Africa). Prof. Agbinya is currently a Faculty member in Information and Communication Group at the University of Technology, Sydney. His research interests are in wireless communications, application of biometrics in digital identity management systems and behaviour tracking in video, networks on mobile platforms (and in uncovered areas) and sensor networks.

H Anthony Chan, University of Cape Town

H. Anthony Chan received his PhD in physics at University of Maryland, College Park in 1982 and then continued post-doctorate research there in basic science. After joining the former AT&T Bell Labs in 1986, his work moved to industry-oriented research in areas of interconnection, electronic packaging, reliability, and assembly in manufacturing, and then moved again to network management, network architecture and standards for both wireless and wireline networks. He designed the Wireless section of the year 2000 state-of-the-art Network Operation Center in AT&T. He was the AT&T delegate in several standards work groups under 3rd generation partnership program (3GPP). During 2001-2003, he was visiting Endowed Pinson Chair Professor in Networking at San Jose State University. In 2004, he joined University of Cape Town as professor in the Department of Electrical Engineering. Prof. Chan was Administrative Vice President of the IEEE CPMT Society during 1997-2005 and has chaired or served numerous technical committees and conferences. He is a distinguished speaker of the IEEE CPMT Society and has been in the speaker list of the IEEE Reliability Society since 1997.
