What is it about?

In the field of Building Internet of Things (BIoT), the full-copy storage mechanism of blockchain and the management requirements of massive data have brought computing and storage challenges to edge nodes with limited resources. Therefore, we proposed a data management scheme for BIoT based on sharding technology. Specifically, sharding algorithm is designed to divide the blockchain into multiple shards, and the storage overhead and computing overhead are offloaded to each shard, which effectively balances the computing and storage overhead of edge nodes.

Why is it important?

Our works can indirectly reduce the cost of operation and maintenance while reducing the performance cost of edge nodes in Building Internet of Things (BIoT) scenarios, and further serve the construction of smart cities.


Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. This article also lead to smart building/urban groups contacting me and ultimately to a greater involvement in related research.
