devices in the Internet of Things (IoT) and other data sources are increasingly bridging the gap between the physical and digital world by providing fine-grained data about real-world events. Enterprise software systems are adopting the paradigm of event-based systems (EBS) to enable them to react

. Yang, W. Lou, and Y.T. Hou explores the problem of secure and reliable cloud storage with efficiency consideration of both data repair and data retrieval and design a LT codes-based cloud storage service(LTCS)..By utilizing the fast BeliefPropagation decoding algorithm, LTCS provides efficient data
