摘要
提出了一种新的切实可行的构建大规模无线传感器网络(LS-WSN,large scale wireless sensors network)的组网策略——"一区多PAN(personal area network)",同时,还提出了一个LS-WSN的两层抽象模型。利用符合ZigBee规范的商业网络协议栈——BeeStack,构建了一个LS-WSN的原型系统。从理论上讲,一个PAN可以支持65536个节点,而一个LS-WSN原型系统可以支持65536×16个节点。实验结果表明,LS-WSN原型系统的服务质量(QoS)可以得到保证。此外,相关分析表明网络管理及数据融合等工作也会被简化,性能相应有所提升。
A new practicable and feasible networking policy was proposed, called one zone multi-PAN （personal area network）. A two-level abstract model of LS-WSN was proposed. Using BeeStack, which was a commercial networking protocol that complies with ZigBee specification, a prototype system of LS-WSN was constructed. Theoretically, a PAN can support 65 536 nodes. Thus, the size of our LS-WSN could be expanded up to 16 times compared to that of a PAN. Experiences show that the quality of service （QoS） of LS-WSN can be guaranteed. Furthermore, analysis shows that the network management, the data fusion, and the performance can be also improved.
