M/I Adaptation Layer Network Protocol for IoT Based on 6LoWPAN

The four-layer network protocol architecture for Internet of Things is proposed based on 6LoWPAN, and the M/I adaptation layer, as the key of the protocol architecture, achieve the integration between underlying networks and Internet. MAC sublayer implement periodic listen/dormant mechanism and carry out unslotted CSMA/CA protocol in condition, and simultaneously fragmentation and reassembly of link frame header is used for link MAC packet. IP sublayer implements EHC scheme which could compress IPv6 global address header, and a IPv6 address autoconfiguration method is proposed in IP sublayer. The test results indicate that the network architecture is well for large-scale Internet of Things and related methods save the network energy and improve the system throughput.
