Design And Implementation On Internet Of Things Information Service System

The Internet of Things Information Service System(IOT ISS)is the key technology of the IOT application layer.To make the Internet as the basis of the information service network,the information can be collected by the underlying various sensors and transmitted to the IOT application server through the IOT terminal node.Then,the information interaction and sharing are realized through the open Internet and the Internet of Things is realized through the Internet of Things application server.The terminal aggregation node connected to the Internet and completed the service request to any sensor node to respond the specific actuator.In the traditional RFID Information Service System(RFID ISS).RFID ISS cannot integrate related information services into the Internet application ecosystem because the system itself is designed independently of the W3 C standard.Therefore,the utilization of the Internet infrastructure of the traditional Internet of Things information service is low,so the system development is difficult.How to effectively improve the low Internet resource utilization rate of the future IOT information service system and realize the integration into the Internet application development ecosystem is the research focus of IOT ISS.With the goal of improving the efficiency of IOT information services,we will make the following contributions around the research and design of the new IOT information service system architecture:(1)According to the Cordova mobile development framework and the Node.js application server development framework for open source cross-platform deployment,compatible with the Internet ecosystem.A Cordova-NodeJS hybrid IOT information service system(C-N HIOT ISS)was researched and designed.The Things Information Service System,which use the hybrid development technology,makes the IOT information service system compatible with the ability to service mobile IoT terminals which can solve a series of problems in traditional IOT information service systems.(2)To realize the construction of the Device to Device(D2D)of the information service system,a method for confirming the proximity of the RSS signal to the terminal terminal based on the MIMO system is proposed.The characteristics of the large-scale multi-antenna and the received signal are analyzed in depth.The indicators of the Received Signal Strength(RSS)use the KPCA-IWKNN algorithm and the PLN-AP algorithm to analyze the spatial position fingerprint of the AP node and reasonably estimate the neighboring terminals near the terminal equipment,thereby directly connecting the D2 D terminal equipment to the network.The build provides the foundation.(3)In order to solve the problem that the mobile terminal and the IOT terminal cannot realize compatible information service under the hybrid development in D2D-MIMO HIOT ISS,a terminal compatibility method and a hybrid data distribution strategy are designed.This enables D2D-MIMO HIOT ISS to provide information services for multiple types of terminal platforms.This paper proposes a D2D-MIMO Hybrid Internet of Things Information Service System(D2D-MIMO HIOT ISS)architecture,which improves the information service efficiency of IOT information service system in the future.The terminal direct connection has low interference and low power consumption.At the same time,the system communication link has high spectrum utilization rate and can be integrated into the Internet application ecosystem.It provides meaningful research results and valuable reference for the future IOT information service system.
