Wireless Sensor Networks (WSNs) and their pivotal role in modern technology. It is basically a wireless network in which sensor nodes are distributed in any environment condition, to collect the data or information such as temperature, pressure, wind, sea level etc [1]. and accordingly data or information will be passed to the main location. Reliable Trust and Reputation of a node stands for the measure of trust over a certain period which can be useful to evaluate the risk of attack from that node. We have combined all these parameters to risk of attack from a particular node. The dynamic nature of WSNs, comprising self-configured and autonomous Sensor Nodes (SNs) that collect specific event data[3]. It highlights the rapid advancements in wireless communication and the emergence of WSNs as a key player in collecting specific event data. WSNs are described as self-configured and autonomous networks of Sensor Nodes (SNs) that operate without fixed infrastructure, enabling dynamic networks and self-organization[4]. The versatility of WSNs in various applications such as habitat monitoring, surveillance, tracking, and smart farming. It underscores the challenges faced by WSNs, particularly in terms of energy-efficiency, node connectivity, localization, scalability, security, and overall network performance. The focus of the work presented the developing energy-efficient routing protocols for WSNs to enhance network longevity and performance. Introduction WSNs are globally-distributed and customized systems to sense and collect atmospheric factors, then transmit this data back to a centralized position. Among other ones, such as heat, sound, particulate matter emissions like dust and smoke, humidity and weather may be detected by WSNs [9].
