  • 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; Kogeda, OP; Van Wyk, BJ (De Gruyter, 2012-09)
    Wireless Backbone Networks (WBNs) equipped with Multi-Radio Multi-Channel (MRMC) configurations do experience power control problems such as inter-channel and co-channel interference, high energy consumption at the multiple ...
  • 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 ...
  • Abu-Mahfouz, Adnan M; Olwal, TO; Kurien, AM; Munda, JL; Djouani, K (IEEE, 2015-09)
    The design of innovative technological instruments and frameworks for smart energy management is a challenge for countries across the world, and the creation of a 'Smart Grid' still has unresolved research and development ...
  • 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 ...
