Wireless network security: Comparison of wep (wired equivalent privacy) mechanism, wpa (wi-fi protected access) and rsn (robust security network ) security
free download
ABSTRACT Wireless Local Area Networks (WLANs) are gaining popularity as they are fast, cost effective, flexible and easy to use. They are, however, faced with some serious security challenges and the choice of security protocol is a critical issue for IT administrators. TheThis paper describes the design and implementation of a distributed self-stabilizing clock synchronization algorithm based on the biological example of Asian Fireflies. Huge swarms of these fireflies use the principle of pulse coupled oscillators in order to synchronously emit
