摘要
针对传统无线传感器网络工作在特定频段的不足,提出了一种双频无线传感器网络汇集节点的设计方法。该方法以433 M和2.4 G为工作频段,采用低功耗MSP430F1611为处理芯片。以CC1101和CC2530作为射频芯片,设计了适应于小范围检测的双频段层次结构无线传感器网络汇聚节点。在MAC协议方面,汇聚节点采用频段外分时和频段内信道竞争的方式进行数据汇聚,提出了适合双频网络的通信协议。最后,通过对比试验验证该汇聚节点的硬件与软件设计方案实现了对2个频段的综合利用,平均丢包率较低,通信质量较高,满足了低功耗的设计要求。
In view of the traditional wireless sensor network operating at a particular frequency band,this paper put forward a kind of dual frequency wireless sensor network sink node method.With low power MSP430F1611 for processing chip,the 433 M and 2.4 G as working frequency band were integrated in this design.For suiting small range detection a dual band sink node of wireless sensor network was designed basing on CC1101 and CC2530 as RF chip.Giving the division time during double band and competing channel in the same band were used for data aggregation.A new MAC protocol was given for fitting the dual-band sensor network.At last,the experiment result demonstrated that the double band sink node scheme achieved integration for two frequency bands and the PER was at low rate.The design had higher quality of communication and met the lower power requirements.
