Abstract :
Smart antennas enable a receiver to determine the direction of arrival (DOA) of multiple transmissions as well as to form s in some number of directions to maximize SINR (Signal to Interference and Noise Ratio) of the received signal. We utilize the benefits of these capabilities to develop a simple modified version of the popular 802.11b protocol. This protocol exhibits high throughput under a variety of network conditions and is fair. The performance of the protocol is examined exhaustively using joint simulation in OPNET and Matlab.
