Design And Implementation Of User-driven Smart Home Application System Based On NDN

Smart home is one of the hot areas of the Internet of Things,which contains a considerable amount and a wide variety of smart terminal resources.The network transmission and categorization of large volume of data generated by sensors,as well as the continuous expansion of the meaning of terminal resources,remain as problems of smart home.Named Data Network(NDN)is one of the proposals for future network architectures.It has excellent natural support for problems in smart home in terms of device scalability,data transmission,and data caching.Aiming at the user's remote control of smart home devices,and taking the initiative control needs of users as the starting point,this thesis design and implement a user-driven NDN smart home control system.The design of the system focuses on five major issues of the semantic rules of the control instructions,the name design of NDN,the service model,the authority management,and the determination conditions of the control trigger.The system uses a hierarchy to name the device name.These names combine the forwarding strategies to define the forwarding range,and make it easier for interest packages to reach the actual location of the node.The system integrates the tree structure and device retrieval table to automatically complete the device name and subsystem type.This design provides users with good interaction and reflects the advantages of NDN naming combined with application functionality.This thesis uses NFD-Android to implement the NDN application on Android platform,and tests in the actual environment.The test results show that the interaction among users and devices in the NDN environment is feasible in the actual environment.
