提出了一种简单的基于现场可编程门阵列(FPGA)模块来实现可重构无线传感器网络节点的方案。与传统方案相比,新方案较为精简,价格低廉,不再需要微控制器,大大减小了节点软硬件复杂度,可实现无线传感器网络节点的快速可重构设计。通过将自适应功率控制和低功耗媒体接入控制机制引入FPGA核,重构的节点大大地降低了功率消耗,充分表明提出的可重构设计方案是有效可行的。

A simple scheme based on Field Programmable Gate Array (FPGA) module to implement reconfigurable wireless sensor network nodes is proposed. Compared with the traditional scheme, the new scheme is more concise and the price is lower. The microcontroller is no longer needed, the hardware and software complexity of the node is greatly reduced, and the reconfigurable design of the node in the wireless sensor network can be realized quickly. By introducing adaptive power control and low-power media access control mechanism into the FPGA core, the reconfigurable node greatly reduces the power consumption, which fully shows that the proposed reconfigurable design scheme is effective and feasible.
