【Abstract】 It is a key technique to combine Wireless Sensor Network(WSN) with current network infrastructure in WSN research.By analyzing the current issues of WSN access to Ethernet and summarizing the characteristics of WSN based on IEEE 802.15.4,a system for IEEE 802.15.4 based on WSN access to Ethernet is designed under IPv6.This system obeys 6LoWPAN specification,and implements the structure of IPv6 over IEEE 802.15.4.To distribute global unicast address for FFD nodes,a tree based address distribution algorithm is demonstrated.A gateway is designed for this system,and the format of controller-packet is introduced,too.A experiment system in miniature is implemented to validate this design.We also analyze the performance of this system.The experiment indicate that it is useful and effective.更多还原
