Abstract:
The Ad Hoc network had the characteristics of self-organization and dynamic topology,so it could be dynamic priority polling strategy for data collection.In this paper,the detailed analysis and research had been done on the data link layer of the Ad Hoc network data acquisition system. In the network link to solve the problem of competition for resources and allocation mechanism,we adopted the way to access the network nodes with dynamic priority polling strategy.At the same time,the channel utilization and system stability were improved.This design took advantage of reconfigurability and flexibility of FPGA,using a hardware description language VHDL to design and Quartus Ⅱ 8.0 to synthesis and routing.Finally the beamforming device to be tested was downloaded to Altera Corporations EP2C35F672C6 chip.The entire hardware design had such advantages as followsimple structure,high reliability,quick real-time.This design coule be widely used in the field of sensor networks,mobile communications network.
