To become an indispensable part of the Internet of Things (IoT), Wireless Sensor Networks (WSNs) have to be integrated into the Internet. Under such circumstances, any IP-enabled node in the Internet shall be able to directly communicate with any sensor node in a WSN. Then, multiple sensor nodes can be used to monitor an event and jointly generate a report to be sent to one or more Internet nodes for monitoring purposes. Hence, it becomes imperative that every event report that is transmitted from within the WSN be authenticated to intended Internet users and efficiently filtered on its way to the Internet users.
