摘要：Wireless Sensor Networks(WSNs) are composed of tiny devices with limited computation and energy capacities. Data fusion is an essential technique to achieve power efficiency in sensor nodes. Some nodes misbehave by increasing the defer time which obstruct the data fusion process. In this paper, an efficient Secured Quality of Service(QoS)-Aware Data Fusion(SQDF) for distributed Wireless Sensor Networks is proposed. The key feature of secure data fusion is to detect the misbehavior of a node which defers the data packet for an extra period of time. Simulation results show that proposed scheme efficiently detects the malicious nodes and decreases the packet drop significantly.
