Network Layer Protocol Research In IPv6Wireless Sensor Networks

Wireless Sensor Networks(WSNs) are widely used in embedded applications, which aremulti-hop self-organizing network composed of a large number of resource-constrained nodes.6LoWPAN which introduces an adaptation layer between the link and network layer of IP stackenable the transmission of IPv6packets over IEEE802.15.4networks. In this thesis, mainly studythe network layer protocol, specially focusing on the address configuration and routing protocols.Firstly, this thesis analyzes several existing IP address configuration protocol in mobileself-organizing network briefly. Due to their flaws, this thesis study a new protocol calledAgent-Node Existed Address Configuration In Turn Based on Clustering. Followed by describingthe principle, data type and working process of this protocol in detail. OPnet medeler analysisresults show this protocol have better performance in overhead and delay than MANETcof.Secondly, this thesis introduces routing protocol in traditional network briefly and thenanalyzes RPL proposed by ROLL Working Group in IETF, including working process, loopavoiding mechanism, repair mechanism, timing mechanism. This thesis also analyzes itsperformance by simulation and the results show that RPL exist some flaws.Thirdly, this thesis does some researches in routing protocol called Based on ClusteringOn-demand routing protocol according to the address configuration protocol researched chapterthree. Followed by describing the principle, data type, routing table and routing constructionprocess of this protocol. OPnet modeler analyzes its performance, and then compares with AODV.This protocol is superior to AODV.Finally, summarize the work of this thesis and list follow-up work.
