Application of HYDRA computer to collect status information for network quality of service

Odhiambo, Marcel O. Van Wyk, Barend J. Van Wyk, Michael A. (SCI, 2005-07-13)

Users of telecommunication services are becoming more adamant about the quality of service offered by network service providers. Users are demanding performance levels which guarantee that user data will not suffer degradation ...
Dynamic pricing in cellular networks for QoS

Aloo, P. Van Wyk, M.A. Odhiambo, M. O. Van Wyk, B.J. (SATNAC, 2005-09)

In this work in progress paper we describe dynamic pricing strategies for network quality of service (QoS) in cellular networks. Dynamic pricing policies allow the network operator to charge a cost per time unit depending ...
Cramer-Rao bound on timing recovery for GSM receivers

Olwal, T. Van Wyk, M. A. Chatelain, D. Odhiambo, M. Van Wyk, B. J. (2006-05-17)

The problem of timing recovery in cellular receiver systems is critical. This is because synchronization functions must follow rapid parameter changes inherent in mobile systems. The ultimate goal is therefore to achieve ...
Dynamic pricing control in cellular networks

Aloo, P. Van Wyk, M.A. Odhiambo, M.O. Van Wyk, B.J. (ICTe Africa, 2006-05-19)

In this paper we present dynamic pricing control for network quality of service (QoS) in cellular networks. Dynamic pricing policies allow the network service providers to charge a cost per time unit depending on the ...
Need for national ICT policy

Odhiambo, Marcel O. (2008)

Information and Communication Technology (ICT), a merger of two technologies; Information Technology (IT) and Communication Technology (CT) to form Information and Communication Technology (ICT) made it possible for combined ...
A new education framework and the impact on vocational qualification offered by South African comprehensive Universities and Universities of Technology

McGrath, P.J. Nickola, L. (International Association of Technology, Education and Development (IATED), 2008-03-03)

Over the past 35 years Engineering Education in South Africa has changed substantially in an endeavour to supply the country with skilled technical manpower. These changes dealt mainly with Institutions offering Vocational ...
The alignment of the information technology’s Enterprise Resource Planning rollout strategy with the business strategy in a semi-governmental organisation

Bopape, Harry Maishe Lubbe, Sam, 1952- Klopper, Rembrandt (2008-07-10)

Enterprise resource planning (ERP) systems are highly intricate Information Systems (IS). The im-plementation of this type of integrated system is difficult and high in cost. It places immense strain on time and resources. ...
Improving video streaming over IEEE 802.11 mesh networks through a cross-layer design technique

Moleme, N. H. Odhiambo, M.O. Kurien, A.M. (Third International Conference on Broadband Communications, Information Technology & Biomedical Applications, 2008-11-26)

There has been a spate of interest in wireless mesh networks in recent years. The reason behind such an upsurge of interest is that wireless mesh networks are seen as enablers of ubiquitous broadband access applications ...
A low variance timing recovery in turbo receivers

Olwal, T. Van Wyk, M. A. Chatelain, D. Odhiambo, M. Van Wyk, B. J. (2009)

This paper presents a fast converging timing recovery algorithm for digital receivers in low signal to noise ratio. This solves the problem of traditional slow converging phase-locked loop-based timing recovery in low ...
Towards a converged network : video streaming over WiMAX vs. HSDPA in the rural environment

Odhiambo, M.O. Amimo-Rayolla, P. O. Kurien, A.M. (AFRICON, 2009-09-23)

As the telecommunications industry evolves towards a converged IP-Core network the role of cellular/wireless broadband technologies in achieving Long Term Evolution (LTE) must be greatly evaluated. This would in effect ...
TESPAR Coded Speech Quality Evaluation (TCSQE) : A New Algorithm for Objective Measurement of Speech Quality in Cellular Networks

Adar, Philip O. Odhiambo, Marcel O. (AFRICON, 2009-09-23)

Speech transmission quality measurement in cellular networks is a major indicator of performance for end-to-end quality of service standards. Many approaches have been proposed in the previous studies, but the results ...
Enhancing video streaming in 802.11wireless mesh networks using two-layer mechanism solution

Moleme, N. H. Odhiambo, M.O. Kurien, A.M. (AFRICON, 2009-09-23)

Multihop wireless mesh networks have emerged as the next generation in wireless network technology. This is due to the advantages provided by the mesh network technology. WMNs provides ease of installation, cost effective ...
The WiMAX PHY Layer

Odhiambo, Marcel O. Rayolla, Amimo P.O. (InTech, 2012-03-07)
Performance Analysis of a WiMAX/WiFi system whilst streaming a video conference application

Umenne, Patrice Odhiambo, Marcel O (World Academy of Science, Engineering and Technology, 2012-08-10)

WiMAX and Wi-Fi are considered as the promising broadband access solutions for wireless MAN’s and LANs, respectively. In the recent works WiMAX is considered suitable as a backhaul service to connect multiple dispersed ...
Performance of an 802.11g/Wi-Fi network whilst streaming voice content

Umenne, Patrice (World academy of Science, Engineering and Technology, 2012-09-26)

A simple network model is developed in OPNET to study the performance of the Wi-Fi protocol. The model is simulated in OPNET and performance factors such as load, throughput and delay are analysed from the model. Four ...
