Multi-hop Ad-hoc Networks) which is designed and implemented for evaluation of routing protocols for multi-hop wireless networks. AEROMAN uses QOMET‚ a wireless link emulation tool‚ to compute parameters of wireless links‚ such as bandwidth‚ delay‚ packet loss rate‚ in contention-free conditions. In order to take into account the properties of contention-based media access for wireless channel‚ AEROMAN uses an Adaptive Traffic (AT) model to emulate the sharing feature of CSMA/CA mechanism in IEEE

created a huge challenge for security specialists is the use of wireless internet connections. Wireless internet connections began in the 1970’s with the creation a wireless network in Hawaii called the ALOHANET‚ which connected seven computers on four separate islands (Goldsmith). Comparing this system to the ones we use today would show many advances in technology since the creation of the ALOHANET. Though this is the first recorded wireless network put in use‚ the idea of the World Wide Web began twenty
