Adaptive antenna arrays in QualNet simulator

Student thesis: Master typesMaster in Computer science


Wireless technology brings many new possibilities to how networks can be used. However many physical phenomenons cause this technology to be less efficient than their wired counterparts. Such problems include Rayleigh Fading and Doppler effect. The problem of frame collision which cause corruption of both frames was solved by the use of a protocol such as CSMA/CA. However this protocol works by preventing simultaneous communication on the shared medium, resulting in larger delays, wasted time and bandwidth. The Adaptive Antenna Array is presented as an alternative to the problem of interference, Rayleigh fading and Doppler effect. We present in this thesis the implementation of this antenna model in the QualNet simulator.
