In order to solve the problems of current 6Lo WPAN edge router only can communication with IPv6 equipment

network data packet transmission complex and the edge router complex mapping table consume valuable resources of single chip micyoco. so

introduce the concept of IEEE 802. 15. 4 address to optimize the packet format in 6Lo WPAN network. The conversion mechanism between 6Lo WPAN and IPv4 protocol

and the mapping method of edge router address are proposed. A lightweight system is designed for 8 bit single chip micyoco. Co AP（ constrained application protocol） protocol is used to access node data and verify the system to realize the communication between 6Lo WPAN network and IPv4 network. This method realizes the interconnection between 6Lo WPAN and IPv4

retains the functions of 6Lo WAPN and IPv6 network

and improves the throughput of6 Lo WPAN

and reduces the overhead of 6Lo WPAN network

increase efficiency of edge router

effectively reduce power consumption data transmission

prolong lifetime of node.
