Wireless LAN deployment has shown an unprecedented growth in recent years. With Wireless LANs users can access mutual information without looking for a place to plug in, and network managers can set up or augment networks without installing or moving wires. WLANs offer various advantages over conventional wired networks, viz., efficiency, service, handiness, and cost. However, vulnerability of WLANs to various attacks discourages the user to use these networks for specific applications. In this paper, the authors have explored the simulation of a popular WLAN standard, when it is being subjected to the dictionary attack.
