Data Acquisition, Filtering and Buffering Protocol Design for Edge Computing Nodes

Edge computing is playing a more and more important role to bridge the gap between industrial clouds and field devices for Industrial Internet-of-Things. How to collect data effectively from various device types becomes one of the major challenges for edge computing. In industrial edge computing, data-related challenges are gradually exposed including compatibility between edge computing nodes, the process specification of data acquisition, and the efficiency of data storage. To solve the above problems, the IEEE P2805.2 Standard is proposed, which provides generic data acquisition, filtering and buffering protocols between cloud and edge computing. In this paper, the data acquisition principle and process of the IEEE P2805.2 Standard are explained in detail. A case study is presented for proof-of-concept of the proposed protocol.
