Abstract :
Internet of things (IoT) has been researched in recently years. The Savant as a midware provides the data collecting and pre-processing for the IoT applications. Data grid can aggregate the resources in the IoT. Using data grid to build the Savant enables the Savant manage large scale data and optimizes the efficiency of the resources in IoT. In this paper, the data in the IoT is classified, and a data grid based Savant is designed. In addition, the key issue of data replication strategy is analyzed, and a advanced cascading strategy is proposed according to the features of the Savant. After the simulation to the strategy, In the simulation of the data replication strategy, the performance of the advanced cascading is lower than that of the cascading by 3.6%. However, the bandwidth consumption and the storage occupation are brought down by 12.5% and 25.9%.
