NASA: A Novel System Architecture for Ad Hoc Networks

A novel architecture used in the Ad Hoc networks is designed for building a well communication network quickly and reliably without any support of base installation. The system including hardware and software, called NASA, is also designed for high data rate transmission. The system architecture of NASA takes collaborative design of hardware and software. Therefore, it is completely open and doesn’t base on any operating system. NASA is designed for distributed networks and every NASA node could communicate with each other coequally. The paper discusses how to build the hardware platform of NASA, the cross layer implementation of the MAC and routing protocol. It has been proved that the proposed system is quite efficient and has low data transmission delay. In our experiments, the highest data transfer rate of NASA can be up to 1Mbps with 120 meters.
