Software-defined wireless sensor networks (SD-WSNs) are introduced with the aim of achieving central control and flexible network management and separates data from control. In SD-WSN, security and energy are two vital issues. However, few studies have provided these two aspects simultaneously. With the widespread deployment of sensor networks and the use of this network, security and trust management issues are becoming a major concern. So far, the main focus of research has been on building practical and useful sensor networks, with less emphasis on security and trust. This study examines the security challenges in software-defined wireless sensor networks and summarizes the key issues that need to be addressed to achieve security. These include an overview of the current situation, solutions to key issues such as secure routing, eavesdropping prevention and management service. This study deals with sensors that, in order to conserve their energy, become selfish nodes and refuse to receive or send data. Trust in such nodes has been researched through four criteria of honesty, intimacy, energy and humility. In this regard, and first, from the combination of two algorithms k-means and kNN, clustering is done based on the number of sensors used by the software defined network, and then the optimal routing, which is based on energy consumption and with priority of trust is considered. The simulation was implemented randomly in three scenarios of 50, 100 and 200 distributed sensors. This research also is considered some safe methods for achieving security in wireless sensor networks, and finally, a proposed integrated approach based on trust to ensure the security of sensor networks is presented. The results of this research show that the proposed model, considering the establishment of trust and has been able to optimal and appropriate energy consumption in all three scenarios.
