Approach To Process Smart Grid Time-Serial Big Data Based On Hbase, Wang Yuan, Tao Ye, Yuan Jun, He Wei
Approach To Process Smart Grid Time-Serial Big Data Based On Hbase, Wang Yuan, Tao Ye, Yuan Jun, He Wei
Journal of System Simulation
Abstract: With the development of critical theories and technologies in Internet of things (IOT), more and more attentions have been focused on the IOT applications. Smart Grid is one of the typical IOT applications on which a huge number of sensors have been deployed to gather and generate time-serial data to make sense of the running states of the key devices. How to apply these data to make smart grid running secure and stable is a hot research topic. By considering the fact that smart grid is characterized by a huge number of devices, a huge amount of data and …

Algorithms For Join Queries In Multiple Wireless Sensor Networks, Shangfeng Mo, Yongjian Fan, Xiaoliang Wang, Qingchun Yu, Yinglong Li
Journal of System Simulation
Abstract: The perception layer of Internet of Things (IoTs) is mainly composed of Multiple Wireless Sensor Networks (MWSNs). Data query processing is a very important research area in MWSNs. Join queries can monitor similar network environments in different positions. In general join algorithm, each ordinary node sends its join attribute value to the database server. The database server finds out the result set which meets the join conditions. In distributed join algorithm, the ordinary nodes predict their filters of next round and the database server obtains the global, common filters. The nodes which meet the join conditions send their data …

Multi-Channel Transmission Optimization Of Campus Internet Of Things Based On Pheromone Genetic Algorithm, Zhiyong Chen, Liu Hao
Journal of System Simulation
Abstract: Aiming at the difficulty in selecting and optimizing the multi-path transmission of campus Internet of Things information, an optimization algorithm of network multi-path transmission based on intelligent optimization algorithm is proposed. Based on the standard genetic algorithm and the concept of pheromone concentration in ant colony algorithm, this algorithm improves the global optimization ability and convergence efficiency by controlling the evolution direction of individuals, and designs and constructs an evaluation index mathematical model which conforms to the characteristics of multi-channel information transmission optimization in the Internet of Things. The mathematical model of the evaluation index realizes the multi-channel comprehensive …

Journal of System Simulation
Abstract: In order to solve the problem of information islands existing in the production process of traditional electrical equipment, this paper proposes a technology for equipment integration into the industrial internet cloud platform. Based on the edge computing and WebService technologies, two models of device integration direct access and indirect access were established. The direct access model was verified by application simulation in a production workshop, which realized the high-speed and stable data transmission between the equipment and the industrial internet cloud platform. The results show that the technology is feasible and effective. The application of this device integration …
