System Design of High Speed Ad Hoc Networking with Directional Antenna

Developing with the node communication ability, the demand of ad-hoc networking has been turned from the terrestrial nodes to the air vehicles. In this paper, we discuss the composition of the communication system that can satisfy ad hoc network which node in this network has high speed (more than 100m/s), and long distance (10km-40km) to each other. Since the project is used in reality, the system design should be based on more mature mechanisms. We analysis the several popular technical in ad hoc network and use some of it to build a system which consist of several mechanisms, Directional Antenna and Multi-Interface and Multi-Channel in physical layer to get higher gain, TDMA in MAC layer, AODV in router layer, all working provide a complete system solution. The simulation results show our scheme can be satisfied the specific scenarios of ad hoc networking between the high speed air vehicles with directional antenna.
