A sinkhole attack is characterized by low difficulty to launch, high destructive power, and difficulty to detect and defend. It is a common attack mode for wireless sensor networks. This paper proposes a sinkhole attack detection and defense strategy integrating SPA and Jaya algorithms in wireless sensor networks (WSNs). Then, combined with the SPA trust model, the trust values of suspicious nodes were calculated, and the attack nodes were detected. The Jaya algorithm was adopted to avoid the attacked area so that nodes can find the route to communicate with the real Sink, and attack nodes are isolated in the network to improve the capabilities of network directional defense. The simulation results show that the improved detection algorithm can effectively detect malicious nodes in the network, and the defense strategy implemented in the attacked area can improve the packet delivery rate, reduce network delay and energy consumption, and improve the security and reliability of wireless sensor networks.

With the development of global renewable energy, DC transmission and DC power distribution technology have been applied on a large scale, and the requirements for DC power quality (PQ) are more stringent. Evaluating DC PQ reasonably and effectively has become a research hotspot at this stage. In this paper, a comprehensive analysis for various indexes of DC PQ is conducted to obtain a unified parameter for describing the characteristics of PQ from an overall perspective. First, weight values of PQ indexes are calculated by combining fuzzy analytic hierarchy process (FAHP) and the improved entropy weight method. FAHP can satisfy the consistency without the consistency test, and the improved entropy weight method is an objective weighting method that can effectively avoid the preference of subjective weighting method. Then, based on a triangular fuzzy function, the membership degree is obtained. Finally, a fuzzy comprehensive evaluation is made. An example analysis is carried out with the data provided by the Gree photovoltaic direct‐driven inverter multi‐variable refrigerant flow system to show the validity of the proposed method for evaluating DC PQ. © 2020 Institute of Electrical Engineers of Japan.
