6LoWPAN Hierarchical Cluster Routing Protocol

6LoWPAN is the short name for the IPv6 low-power wireless personal area network. Traditional 6LoWPAN use RPL routing protocols. When the RPL protocol is in storage mode, each node needs to keep the routing information of all the nodes in the subtree. When the network size is large, the number of the node's routing table entry will be very large. This paper presents a hierarchical cluster routing protocol (HCRP). This is a switch-based routing protocol, different from the traditional routing protocol. It contains the routing path information in the node's IP address. It can solve the above problems. Each node stores only its parent node information and a small amount of configuration information. Finally, it is proved that the HCPR is superior to the traditional RPL protocol in many aspects.
