Abstract

In recent years, wireless sensor networks (WSNs) have become a useful tool for environmental monitoring and information collection due to their strong sensory ability. Whereas WSNs utilize wireless communication and is usually deployed in an outdoors environment, which make them vulnerable to be attacked and then lead to the privacy disclosure of the monitored environment. SUM, as one common query among the queries of WSNs, is important to acquire a high-level understanding of the monitored environment and establish the basis for other advanced queries. In addition, now-a-days WSNs are using everywhere such as road traffic monitoring, CCTV home monitoring and many more. They are small and tiny devices which sense the data from its environment and report to the centralized server for remote monitoring using Internet of Things (IoT) network connections. But sometimes malicious attackers can intrude or intercept network connection to alter messages and these altered messages will report to centralized server which many take wrong decision based on received data.
