Applications of Wireless Sensor Network

Mahima Payala


Wireless sensor networks (WSNs) have grown in popularity in recent years and have a wide range of applications, including health, the environment, and the military. Despite its impressive capabilities, the creation of WSN remains a difficult endeavor. Several programming approaches that focus on lowlevel system concerns have been offered in current real-world WSN installations. WSNs are a type of network made up of interconnected sensor nodes that communicate wirelessly in order to gather data about the environment. Nodes are often low-power and distributed ad hoc and decentralized. Despite WSNs have grown in popularity, resource constraints in memory, compute, battery life, and bandwidth pose severe challenges when it comes to establishing security. Attacks on privacy, control, and availability can all be targets. This study assesses the requirements for encryption, authentication, lightweight public key infrastructure proposals, and identity management in WSNs. The issue of new WSN routing methods that consider energy consumption is discussed. WSN is then highlighted as an important technology that enables the Internet of Things in the article (IoT). Because of the large number of "things" and the system's openness, security is projected to be a big concern for IoT. In addition to the usual security goals, the IoT should be intrusion tolerant and self-healing (privacy, authentication, and access control).
