ABSTRACT:
The present invention provides a method, apparatus, and a computer program product for selective directional wireless communication. The apparatus comprises a computer system with a directional communication module. The present invention takes advantage of directional antennas in order to optimize wireless communication by minimizing interference with neighboring nodes. The technique presented is a CSMA/CA-based reservation protocol that improves the multiple access throughput of a wireless ad-hoc network by efficiently utilizing the interference reduction feature of switched-beam antennas by balancing the number of neighbors that need to back-off and the number of control/data packet collisions.
