A 6LoWPAN IoT Platform on the Global Internet
Zengxu Yang, Cheng‐Chieh Chang · International Conference on Embedded Wireless Systems and Networks · 2019
This paper describes a platform under development that runs globally interconnected IP IoT networks based on 6LoWPAN through an IPv4/IPv6 mixed environment. Border routers running 6LBR on Linux are used to interface constrained nodes running Contiki with external IPv6 networks.in4 tunnels are used to encapsulate IPv6 packets inside IPv4 packets where native IPv6 networks are not available and the number of IPv4 addresses are severely restricted. All the constrained nodes are assigned global IPv6 addresses and are globally routable. End-to-end connectivity is achieved by eliminating NAT in IPv6. Firewall guidelines to make this platform work are also discussed. Configurations and testing results of our 6LoWPAN platform testbed are described. Testing results show that our platform meets design goals and can be used for further IoT development.
