 为满足无线网络技术具有低功耗、节点体积小、网络容量大、网络传输可靠等技术要求，设计了一种以MSP430单片机和CC2420射频收发器组成的无线传感节点。通过分析其节点组成，提出了ZigBee技术中的几种网络拓扑形式，并研究了ZigBee路由算法。针对不同的传输要求形式选用不同的网络拓扑形式可以尽大可能地减少系统成本。同时针对不同网络选用正确的ZigBee路由算法有效地减少了网络能量消耗，提高了系统的可靠性。应用试验表明，采用ZigBee方式通信可以提高传输速率且覆盖范围大，与传统的有线通信方式相比可以节约40%左右的成本。
Abstract:
 To improve the proposed technical requirements such as low-ower， small nodes， large capacity and reliable network transmission， wireless sensor nodes based on MSP430 MCU and CC2420 RF transceiver were designed. This paper provided network topology of ZigBee technology by analysing the component of the nodes and researched ZigBee routing algorithm. Aiming at different requirements of transmission mode to choose the different network topologies form can most likely reduce the system cost. And aiming at different network to choose the correct ZigBee routing algorithm can effectively reduced the network energy consumption and improved the reliability of the system. Results show that the communication which used ZigBee mode can improve the transmission rate， cover more area and reduce 40% cost compared with traditional wired communications mode.
