Efficient processing of multiple nested event pattern queries over multi-dimensional event streams based on a triaxial hierarchical model

作者:

Highlights:

• A triaxial hierarchy is proposed to realise the relationships among queries.

• A novel strategy (MQOS) is proposed to find an optimised query execution plan.

• MQOS strategy outperforms other methods even facing the burst input rates.
