The Network Formation And Routing Optimization Based On 6LoWAPN

Wireless sensor network integrates information collection,information transmission and information processing.It has broad application prospects and is one of the hotspots in the field of wireless networks.Configuring addresses through traditional IPv4 protocols is no longer sufficient for a growing number of personal computers,so there is nothing that can be done with a large number of wireless sensor devices.The emergence of IPv6 solves this problem.6LoWPAN(IPv6 over Low-Power Wireless Personal Area Networks)is a technology that studies how to run the IPv6 protocol over wireless sensor devices.6LoWPAN wireless sensor networks have broader application prospects and will play an important role in environmental monitoring,medical monitoring,and smart home.Before 6LoWPAN WSN performs proper communications,network construction and routing must be established.In this paper,the network construction and routing optimization for 6LoWPAN WSN are studied,and the main works include:(1)an mechanism based on multi-hop clusters is proposed to avoid the addressing failures caused by the lack of cluster heads and improve the addressing success rate;(2)a network construction algorithm based on cluster trees is proposed.Since the cluster tree is constructed by beacon frames,the network construction cost and delay are effectively reduced;(3)Based on the mobility of the WSN,a dynamic routing optimization algorithm is proposed to reduce the routing cost and delay.Finally,through build simulate platform test the network connectivity and captured the data transmitted between nodes.
