基于FPGA的动态优先轮询策略在Ad Hoc网络数据采集系统中的研究与应用

The research and application of dynamic priority polling strategy based on FPGA in Ad Hoc network data acquisition system

  • 摘要: Ad Hoc网络具有自组织和动态拓扑的特性,因此可采用动态优先轮询策略对其进行数据采集.该文对Ad Hoc网络数据采集系统中的数据链路层进行了详细分析和研究,通过运用动态优先轮询策略访问网络中各节点,解决了网络链路中资源竞争和分配机制中存在的问题,提高了信道的利用率及系统的稳定性.该系统利用FPGA的可重构性和灵活性,采用硬件描述语言VHDL进行设计,使用Quartus Ⅱ 8.0进行综合和布线,最终以Altera公司的EP2C35F672C6芯片为下载目标进行测试,整个硬件设计结构简单、可靠性高、实时性好.可广泛应用于传感器网络、移动通信网络等领域.

     

    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.
