A wireless sensor network (WSN) consists of geographically distributed, self-governing sensors that collect information about the network's environment. While biomedical sensors are effective and secure in their data collection and prevent potentially dangerous user actions within the network, it is still difficult to identify attacks from regular sensor nodes. Data requests and responses must be validated as part of authentication in wireless sensor networks (WSNs). Authentication is therefore the most crucial security measure. The Internet of Things requires lightweight authentication solutions for low-resource sensor nodes to operate effectively. Three factors were used in the development of a novel authentication system to achieve these objectives. As per the study's findings, the proposed system outperforms all previous comparable protocols, which makes it ideal for applications that use the WSN. Its efficiency can be measured by examining the transmission and computation expenses. This makes it possible for authorized users to access real-time sensing data from WSN sensor nodes after registering for the service. Before granting access to the network, WSN sensor and gateway nodes must verify a user. Among these are their mobility, scalability, dependability, and power efficiency. Performance can be energy efficient. It is unable to account for noise and increased traffic. They employ energy-efficient performance, protocols, modulation techniques, and algorithms. The cross-layer design of the wireless sensor network was covered in this survey. The network life time and throughput are being improved by further implementing the new low power MAC technology and dynamic node traffic analysis.
