Abstract:
In this tutorial we discuss smart antennas and their use in wireless ad hoc networks . We first describe smart antennas and their application in a wide variety of wireless systems, including cellular and wireless local area networks. We then consider wireless ad hoc networks with smart antennas, including directional antennas, beamforming/adaptive antennas, and/or multiple-input-multiple-output (MIMO) techniques. We describe the substantial improvement in performance that these antennas can provide, including collision avoidance, lower latency, higher capacity, and longer battery life. The issues faced when using smart antennas in wireless ad hoc networks will also be addressed, including neighbor discovery, as well as how MAC and routing techniques can be modified to get the maximum benefit from smart antennas.
