基于Msp430无线安防传感网的设计研究

文中给出了一种面向无线传感网络协议的改进方法，设计并实现了一种面向于中小型场所的远程智能安防系统。该改进方法采用只在中心节点形成与维护路由表的策略，形成多路径单跳网络。通信节点采用具有超低功耗特性的Msp430单片机和CC1101射频模块构架，中心节点采用PC机外接CC1101RS-232串口模块方案，将汇聚节点和基站服务器合二为一，实现通信协议的转换，同时为远端移动终端节点提供通信接口。通信过程增加接收确认信号环节以确保信号的有效发送。实验结果表明，文中的设计方法能够高效地完成在有效通信范围内的信息传感。

Design and Research of Security for Wireless Sensor Network Based on Msp430

An improved method for wireless sensor network protocol is presented, and a remote intelligent secure system for small and me- dium-sized places is designed and realized. The improved method uses a strategy that the routing table is only formed and maintained in the center node to form multi-path single-hop network. The communication nodes consist of ultralow power Msp430 MCU and CC1101 RF module. The central node employees a PC with CC1101 RF module to combine the sink node and base station, which realizes to con- vert the communication protocol and provide communication interface for remote mobile terminal nodes. The work adds acknowledge to ensure the effective transmission in the communication process. The experimental result shows that the design method proposed in this pa- per has a good performance in information sensing within effective communication range.
