6LoWPAN Gateway Based on Dual-MCU
Wei Zhang · Jisuanji gongcheng · 2008
6LoWPAN architecture is a series of technologies and standards on running IPv6 protocol stack over IEEE 802.15.4 LoWPAN. This article analyzes the necessity of the gateway for 6LowPAN and describes the main function of the gateway. Based on the analysis of the IEEE 802.15.4 MAC primitive delivery mechanism, it proposes a dual-MCU-based gateway architecture and provides the design of the gateway in detail, including hardware architecture and protocol architecture, as well as the communication of data and primitives between two MCUs.
