Smart physical layer based directional communication networking

In this paper, a smart physical layer based directional communication networking approach is described. It consists of “smart nodes,” equipped with multiple directional antennas and propagation modeling capabilities. This approach brings more “intelligence” (digital logic) in the physical layer to enable full directional communication networking operation without requiring changes in the upper OSI layers. Smart nodes consist of six-sectors, each having a scanning array for user discovery and a dynamic beamforming array for maintaining communication with users. Procedures are developed to enable seamless full-directional link between mobile users and smart nodes, within WiFi and LTE set standards. Simulations are performed using Matlab, and obtained results show successful tracking and continued maintenance of high data rate communication with mobile users.
