A transmission scheme of IPv6 packets over WIA-PA networks

In this paper, we propose an Internet Protocol Version 6 (IPv6) packet transmission scheme for Wireless Networks for Industrial Automation-Process Automation (WIA-PA) networks. According to the specific demands of WIA-PA networks, we establish the improved WIA-PA protocol stack architecture for IPv6 technology, and design the transmission format of IPv6 packets for WIA-PA networks. Furthermore, based on the characteristics of WIA-PA networks, the IPv6 address auto-configuration method is also proposed. The test results show that WIA-PA networks can support IPv6 key technologies through the proposed IPv6 packet transmission scheme, which lays the foundation for the development of the interconnection between Internet and WIA-PA networks.
