| 摘 要： | Ad hoc网络由于具有无中心、自组织、机动性高等特点，越来越受到重视。为实现Ad hoc网络，在无线点对点通讯模块的基础上，加入了MAC协议，以实现网络中寻址及避免数据冲突等功能。模块采用MSP430作为主控芯片，采用具有多信道的nRF905作为收发芯片。文中给出了硬件驱动和多点传输数据的MAC协议。该协议充分利用了多信道特点，各信道同时传输数据互不干扰，提高了传输效率；利用跳频机制保证了数据的准确性，增加了系统的鲁棒性。

| Abstract: | Ad hoe network is more and more popular for its acentric , self-organizing and highly flexible characteristics. An Ad hoe network is realized by adding MAC protocol based on wireless point to point transceiver for addressing and avoiding of data conflict. The module takes MSP430 as center chip while nRF905 as transceiver, which has lots of channels. First the hardware driver is put forward, then MAC protocol is given in the paper. The protocol makes use of multiple channels while data can be communica- ted simultaneously in different channels which enhances efficiency. Adopting hopping method when error occurs, which ensures veracity and improves robusticity. |
