A taxonomy of quality of service aware adaptive event dissemination middleware

This paper has to be read later in more details. It provides an overview of EBMs and the set of QoS requirements that they need to admit to.

Probelm that paper tries to address:

few middleware options provide support for nonfunctional service guarantees. There is a lack of comprehensive survey that analyzes all the EDMs providing support for QoS.

some of the QoS requirements for the EBM or EDM

• security
• load balancing
• reliability
• fault tolerance
• ordering
• semantics delivery

The event model has three message types

• advertisement
• notification
• subscription

There are two types to composite events

• temporal: time dependencies between primitive events.
  
• spatial: conjunctive/disjunctive combination of individual events
