Research On Interconnection Scheme For Wireless Sensor Networks And IPv6 Network

WSN (short for Wireless Sensor Networks), the new network with rapid development and great significance in recent years, whose emergence has made a profound impaction on modern society. With the vigorous development of WSN and potential advantages of IPv6 protocol, the researches on interconnection scheme for WSN and IPv6 Network are being intensely underway currently.For seamless connection of the two heterogeneous networks, WSN and IPv6 network, a new improved interconnection scheme is proposed in this paper with the analysis of current schemes, and then the detail designs of each functional component, meanwhile simulation in NS2 through the expansion of SSCS module in NS2802.15.4 simulator.Firstly, introduction of WSN including the architecture, features, application scenarios, etc, meanwhile the theoretical analysis of IEEE 802.15.4 and IPv6 protocol.Secondly, analysis of the three interconnection schemes for WSN and IPv6 network currently, with a comprehension of whose shortcomings, a new improved scheme is proposed with simplicity, flexibility, reliability and low power consumption, additionally the detail function introduction of components. Meanwhile, specific design of the two modules in new interconnection model:IPv6-based WSN and multi-user proxy server.Thirdly, with the expansion of SSCS module in NS2 802.15.4 simulator, NS2 simulations of TCP/IPv6-based and new improved interconnection scheme are done respectively, meanwhile with the four performance data diagrams generated from analysis of AWK scripts, the feasibility of new scheme being proved. Finally, conclusion of this paper, point out the defects of the design and propose directions of further research.The researches on interconnection for WSN and IPv6 network are still being immature. However, do believe that with the continuous deepening and development of relevant researches, the application prospects of WSN will surely be raised to a new stage.
