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.

Abstract: A computer network uplinking system, method, and computer program product are presented for allocation of network resources. A controller tier includes a controller node 100 having a processor 102, a memory 104, and a communication interface 106. Also, an uplinking tier includes uplinking nodes 108, with a processor 110, a memory 112, and a communication interface 114. The nodes 108 communicate the controller node 100 in frames. Current and next frames are represented as K and K+1. The nodes 108 request reservations from the controller node 100 based on the data each needs to transmit. The controller node 100 generates a control signal based on the reservation requests to assign slots of a information subframe of the next frame K+1 to the nodes 108 based on the priority allocated to the node 108 and the data each needs to transmit. The nodes 108 then transmit in their assigned slots.
