wireless sensor network IPv6 IEEE802.15.4 6LoWPAN TinyOS adaptation layers header compression
IEEE802.15.4 network properties determine that IPv6 can not be directly built on IEEE802.15.4.In order to achieve IPv6 over IEEE802.15.4,this paper describes the 6LoWPAN core technologies: the frame format,the fragmentation and reassembly of the adaptation layer,Mesh support and header compression.Combining the TinyOS’ features,a 6LoWPAN p2p network based on TinyOS 2.0 is designed and implemented.The implementation details of the 6LoWPAN p2p network are presented as follows: the framework of the network,the establishment of the system’s core technologies and the design of the system buffers.An environment to test the 6LoWPAN network is designed.The test results show that the system works well and can implement the target that the WSN exchanges data directly with the external IPv6 network.
