The Design And Realization Of Sensor Node Of Wireless Sensor Network Based On Lightweight IPv6Protocol

This thesis is based on Internet of things. This article studies the related technology of sensor nodes in wireless sensor networks, puts forward a design scheme of sensor nodes in wireless sensor network based on IPv6, and realized the sensor nodes in a wireless sensor network system. The main work of this paper include the following aspects:1. Introduction of Internet of things applications background, system architecture analysis of wireless sensor networks and confirming the functional requirements of sensor nodes.2. Design of the hardware and the function of each module of sensor node, lightweight IPv6protocol stack and the Routing system of the various scenarios. The key job is to design the lightweight IPv6protocol stack reference to the IETF protocol standard about sensing layer.3. Proposed several optimization design of the sensor node, including routing protocol optimization scheme, the data storage and query method and the node authentication method of self-organizing network. These optimization design are mainly used in Energy limited occasions which effectively improve the system stability.4. Implementation and verification of the monitoring function and the communication function of sensor node, focuses on the implementation of lightweight IPv6protocol stack and routing forwarding function. After Functional verification is successful do the large-scale deployment of sensor nodes and test the function of the realization of the system implementation and the stability.
