Abstract: With the increasing demand for new applications in wireless sensor networks (WSN), the low-speed wireless personal area network standard 6LoWPAN, which implements IPv6 communication based on IEEE 802.15.4, is an ideal solution for connecting WSN to the Internet for full IP communication. This paper proposes a multicast communication scheme based on 6LoWPAN network, which adds support for multicast communication to the existing 6LoWPAN network by self-organizing MAC address. The 6LoWPAN network multicast communication scheme is designed. It reduces the delay of receiving gateway data by the nodes in the group and the processing consumption of irrelevant data by the nodes outside the group. The results show that the node delay under the multicast communication scheme is 15.13% of that under unicast communication, and the data processing efficiency of out-of-group nodes is 39.02% higher than that of out-of-group nodes under broadcast communication. This communication scheme can obtain the expected function and performance, and the 6LoWPAN node can join and exit the multicast group dynamically and receive information within the multicast group.
