The fast one. 1 Introduction. Wireless Sensor Networks WSNs are an emerging technology in existing research and have the potential to transform people's way of life, i.e., make life more comfortable. A wireless sensor is the smallest unit of a network that has unique characteristics such as large-scale support, mobility, reliability, etc.; Many applications have been developed with the rapid rise of the Internet of Things, IoT, and wireless sensor networks (WSNs) in healthcare. Healthcare applications using wireless medical sensor networks (WMSNs) provide competent communication solutions to improve people's lives. WMSNs rely on highly sensitive energy and security are major challenges in a wireless sensor network, and they work in opposite directions. As security complexity increases, battery consumption will increase. Due to the limited power of wireless sensor networks, options to rely on the security of ordinary protocols embodied in encryption and key management are useless, because wireless sensor networks are the modern remote systems for screening the ecological state. For example: sound, vibration, temperature, weight movement and to gently transfer the information through the system to a primary area or sink, where the information can be detected. WSNs are widely used in various smart cities. Wireless sensor network WSN has emerged as one of the most promising technologies for the future. This has been made possible by advances in technology and the availability of small, cheap and smart sensors, resulting in cost-effective and easily deployable WSNs. However, researchers must address a variety of challenges. Energy and security are major challenges in a wireless sensor network, and they work in opposite directions. As security complexity increases, battery consumption will increase. Due to the limited power in Abstract. With the increasing adoption of wireless sensor networks (WSNs) in military, commercial, and home environments, securing the data in the network has become a critical issue. Various security mechanisms, such as TinySec, have been introduced to meet the need for security in WSNs. However, the cost of security is the wireless sensor network WSN consists of a large number of closely spaced sensors. There are various. applications of WSNs such as military, environmental monitoring, surveillance, healthcare. Secure routing is crucial for WSNs of wireless sensor networks because they are vulnerable to various attacks. In this paper, we propose a new secure routing protocol for WSNs in the presence of malicious nodes. For each relay node in the route, the protocol takes into account associated information, such as the trust value and status; Abstract. Wireless sensor networks are susceptible to a large number of security threats, and due to the communication, computation and delay limitations.
