摘要
阐述了通过心电采集节点、6LoWPAN边界路由器构建无线传感网络,实现了无线传感器网络(WSN)与IPV6网络之间的通信;针对RPL网络协议中的Trickle算法机制导致选择次优链路,影响网络路由的可靠性和稳定性问题,提出了优化方案;开展了仿真测试和优化后的网络性能指标分析;测试结果和分析表明,6LoWPAN无线传感网络不仅可以完成WSN与外部IPv6网络之间的连接承载数据收发,并且在对Trickle算法优化之后,对提高网络性能有较高影响。
Describes the construction of a wireless sensor network through ECG acquisition nodes and 6LoWPAN border routers to realize the communication between the wireless sensor network(WSN)and the IPV6 network;the Trickle algorithm mechanism in the RPL network protocol leads to the selection of sub-optimal links,which affects the reliability and stability of the network routing.This paper proposed an optimization scheme.Carried out simulation test and optimized network performance index analysis.The test results and analysis show that the 6LoWPAN wireless sensor network can not only complete the connection between WSN and the external IPv6 network to carry data transmission and reception,but also has a high impact on improving network performance after the Trickle algorithm is optimized.
