6LoWPAN (IPv6 over Low power Wireless Personal Area Networks), which wraps the IPv6 packets using IEEE 802.15.4 format and standard, is the Internet of Things(IOT) protocol that is currently being developed by the IETF 61owpan working group. CoAP (Constrained Application Protocol) is the application protocol designed for constrained network environment for IOT applications, currently under development in the IETF core(Constrained RESTful Environments) working group. This article introduces the current IETF IOT technologies and gives a 6LoWPAN application example. Our goal is to propose a workable implementation by leveraging the IOT technologies to meet the future intelligent application platform communication needs.
