摘要
将IPv6应用到WIA-PA网络中存在地址转换困难、路由发现开销大等问题。结合工业无线WIA-PA网络的双层通信架构及IPv6地址分配方式,提出一种应用于WIA-PA网络的分段式无状态地址编址策略,将WIA-PA网络地址转换为IPV6地址;最后利用环形层次路由搜索策略对AODV路由进行优化,提高路由发现效率,并降低数据报文间的冲突几率。实验结果表明,该编址方法能够在WIA-PA网络快速实现IPv6地址转换,改进后路由算法能有效提高数据传输过程中的报文投递率并降低端到端时延。
The ineffective address translation and high routing discovery overhead are main problems of IPv6 used in WIA-PA networks.Combined with industrial wireless WIA-PA network two-tier communication architecture and the address allocation mechanism of IPv6,a novel segmented stateless address configuration strategy used to convert WIA-PA network address to IPV6 address is proposed. The AODV routing is optimized based on the ring hierarchical routing searching strategy and it can improve the efficiency of routing discovery and reduce the confliction probability of the data message transmission. The experimental results show that the address mechanism can quickly complete the IPv6 address translation in WIA-PA network,and the improved routing algorithm can enhance the packet delivery ratio of the data transmission and reduce the end-to-end delay.
