Wireless sensor networks (WSNs) having spatially dissipated and independent sensors for detecting heterogeneous events of industrial, military, environmental and health care services for betterment of society. Power efficiency, security and performance are the significant concern regions in designing WSNs. In real-world scenario the communication using wireless sensor networks (WSN) is becoming highly vulnerable and insecure. Numerous security mechanisms have been introduced for secure communication using WSN however none were accomplished the required level of security, performance and energy efficiency. Considering these essential requirements, it is highly essential to design a hybrid mechanism which can give the mentioned characteristics to provide energy efficient secure transmission in wireless sensor networks. Our experimental results are demonstrating that the proposed mechanism has achieved high performance in terms of packet delivery ratio (PDR), network throughput, energy-efficiency and secure communication in WSN. © 2020 School of Science, IHU.
