Impact of New Highly Secure Scheme on Wireless Network 802. 11 Performance

Abstract

local area networks (WLAN) are beginning to play a much larger role in corporate network environments and are already very popular for home networking applications. This increase in accessibility has created large security holes for hackers and thieves to abuse, that is finally being addressed by stronger security protocols and these security protocols include Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA) and 802.11i (WPA2). In this paper, we investigate the performance of wireless local area networks (WLANs) and security protocols available for WLANs. These existing security protocols have certain vulnerabilities and often hamper network performance as maintain poor trade-off between security and overhead on network performance. Here we propose our security protocol Slot Based Security Scheme (SBSS) in wireless local area network. Our proposed security protocol SBSS drastically increases the security and incurs almost same overhead on network performance as other existing security protocols in WLANs. We also develop our simulator in c++ to examine the impacts of these existing security protocols and our proposed protocol SBSS in WLANs on network performance that proves that our proposed scheme SBSS is much more efficient than existing security protocols in WLANs as SBSS maintains good trade-off between security and its associated overhead incurred on network performance.
