  • Olwal, TO; Van Wyk, BJ; Djouani, K; Hamam, Y; Siarry, P; Ntlatlapa, N (SATNAC 2010, 2010-09)
    Multi-Radio Multi-Channel (MRMC) WMNs result in power control problems including interference, un-scalable connectivity and energy consumption. Several previous studies have focused on the single radio wireless configurations ...
  • Olwal, TO; Van Wyk, BJ; Ntlatlapa, N; Djouani, K; Siarry, P; Hamam, Y (Macrothink Institute, 2010)
    With the tremendous growth of wireless networks into the next generation to provide better services, Wireless Mesh Networks (WMNs) have emerged to offer ubiquitous communication and seamless broadband applications. WMNs ...
  • Luhandjula, T; Djouani, K; Hamam, Y; Van Wyk, BJ; Williams, Q (2010-05)
    This paper describes an algorithm for a visual human-machine interface that infers a person’s intention from the motion of the hand. Work in progress shows a proof of concept tested on static images. The context for which ...
  • Olwal, T; Okech, J; Hamam, Y; Kurien, A; Odhiambo, M (IFIP International Symposium on Wireless Communications and Information Technology in Developing Countries, 2008-10)
    As Voice over IP (VoIP) becomes a reality, service providers will be able to offer the service to remote and over populated areas that currently are not or are only partially reached by available Public Switched Telephone ...
  • Olwal, TO; Van Wyk, BJ; Djouani, K; Hamam, Y; Siarry, P; Ntlatlapa, N (Institute of Electrical and Electronics Engineering (IEEE), 2009-09)
    Multi-Radio Multi-Channel (MRMC) systems are key to power control problems in WMNs. In this paper, we present a dynamic power control for MRMC WMNs. First, WMN is represented as a set of disjoint Unified Channel Graphs ...
  • Olwal, TO; Djouani, K; van Wyk, BJ; Hamam, Y; Siarry, P; Ntlatlapa, N (World Academy of Science, Engineering and Technology (WASET), 2009)
    Multi-Radio Multi-Channel (MRMC) systems are key to power control problems in wireless mesh networks (WMNs). In this paper, we present asynchronous multiple-state based power control for MRMC WMNs. First, WMN is represented ...
  • Aron, FO; Olwal, TO; Kurien, A; Hamam, Y (2nd IASTED Africa Conference on Modelling and Simulation - AfricaMS 2008, 2008-09)
    Wireless mesh networks (WMNs) is becoming a promising new technology for extending coverage to farflung rural areas. This it achieves by linking the various wireless LANS (WLANs) in distant locations thus providing a vital ...
  • Olwal, TO; Djouani, K; Van Wyk, BJ; Hamam, Y; Siarry, P (InTech Publishers, 2011-01)
    This chapter proposes a scalable singularly perturbed weakly-coupled TPM which is supported at the LL of the network protocol stack. Firstly, the WMN is divided into sets of unified channel graphs (UCGs). A UCG consists ...
  • Olwal, TO; Van Wyk, BJ; Djouani, K; Hamam, Y; Siarry, P; Ntlatlapa, N (2009-08)
    Multi-Radio Multi-Channel (MRMC) systems are key to power control problems in Wireless Mesh Networks (WMNs). In this paper, researchers present a range based dynamic power control for MRMC WMNs. First, WMN is represented ...
  • Olwal, TO; Van Wyk, BJ; Hamam, Y; Ntlatlapa, N (IEEE, 2009)
    This paper addresses the problem of a scalable dynamic power control (SDPC) for wireless mesh networks (WMNs) based on IEEE 802.11 standards. An SDPC model that accounts for architectural complexities witnessed in multiple ...
  • Olwal, TO; Ntlatlapa, N; Hamam, Y; Aron, F; Van Wyk, BJ; Johnson, DL (2008-09)
    This paper presents an analytical model for the selection of the transmission power based on the bi-directional medium access information. Most of dynamic transmission power control algorithms are based on the single ...
