• Evaluating IPv6 in peer-to-peer 802.11n wireless LAN 

      Kolahi, Samad; LI, Peng (IEEE Computer Society, 2011-08)
      IPv6 is built into the latest versions of Microsoft Windows and Linux-based operating systems. It's expected to replace the current IPv4 and solve its numerous problems, such as address exhaustion, security, and mobility. ...
    • The impact of human shadowing/movement on performance of 802.11ac client-to-server WLAN 

      Kolahi, Samad; Almatrook, A.A. (University of Bahrain (Zallaq, Bahrain), 2019-05-01)
      This paper investigates the impact of human movement on 802.11ac WLAN performance using IPv4, IPv6, TCP and UDP protocols. The results show that on average, the TCP and UDP on WLAN with human movement has a lower throughput ...
    • Other-cells Interference in CDMA systems 

      Kolahi, Samad; Williamson, Allan G.; Sowerby, Kevin William (Institution of Engineering and Technology (IET), 2004-09-20)
      Using simulation and modelling, the other-cells interference factor for CDMA systems is obtained. Situations with tiers of neighbouring cells are investigated under various propagation parameters and for two scenarios, ...
    • Performance analysis of some operating systems in wireless 802.11n networks 

      Kolahi, Samad; Li, Peng (University of Bahrain (Zallaq, Bahrain), 2016-01-30)
      In this paper, the performance of some operating systems (Windows 7, Windows XP, and Fedora 12) are evaluated over IEEE 802.11n WLAN (Wireless LAN), for TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), ...
    • Performance comparison of peer-peer vs client-server 802.11ac WLAN using 80Mhz channel size 

      Kolahi, Samad; Sooran, A. K.; Khan, M.M.U.; Nasim, M.F. (2019-09-01)
      In this paper, the performance of IEEE 802.11ac wireless LAN using IPv4, IPv6, TCP, UDP, peer-peer, and client-server networks is investigated while implementing WPA2 security. The latest operating systems are used in the ...
