The Research of Long-Chain Wireless Sensor Network Based on 6LoWPAN

Long-chain wireless sensor network exhibits a special topology with the nodes distributed in one line just like a long chain. The wireless nodes in this special topology cannot directly access the Internet and the data in the transmission process prone to collision. The 6LoWPAN standard makes it possible for nodes within each wireless sensor network to connect the Internet. According to the characteristics of Long-chain wireless sensor networks and combining with the 6LoWPAN standard, an address allocation method is proposed, which allocates IP addresses for the node in Long-chain wireless sensor network. By compressing the network address of the data frame to improve the data transmission efficiency. In this paper, we also propose a dynamic routing protocol based on maximum routing radius (DMR) to avoid data collision in the transmission process and improve sys-tem responsiveness. The experimental results show that the nodes in the network can interact with the users via the Internet, the stability and responsiveness of the network are greatly improved.
