Abstract
An application scenario, the multi-users scenario in wireless sensor networks (WSNs), was defined in this article, where a large number of queries were generally sent from thousands of users in a large-scale monitored region and they would be a very heavy load for query processing. To deal with this multi-user scenario, the Network Event Report (NER) query processing method is proposed. With this method, the queries are sent to the exact event regions based on the information reported by the event reporting mechanism employed in the NER. In order to restrict the distribution of queries within the even region, a special subnet, the embedded network (EN), is employed in the NER. Simulation results show that the proposed NER approach can work effectively in multi-users scenario.
