Event matching based on subscriber category in sensor cloud

Sensor cloud infrastructure is composed of wireless sensor network and cloud computing technology. The limitation of wireless sensor network can be overcome by integrating it with cloud. The sensor data are collected and stored in cloud for processing that helps to make real time alert in critical situation used for future analysis. Distributing the sensor data to appropriate subscriber is more important. In existing work many event matching algorithms are discussed. The matching is performed on the basis of their predicates and requires more space for indexing all the predicate values. In our proposed work publisher/subscriber model has been taken. In the first stage, subscriptions are categorized on the basis of their privilege and in next stage the events will be matched to the subscription. By this method the subscription storing and matching can be made easier and faster.
