The usage of mobile devices and sensors-based Internet of Things communication technology is growing quickly nowadays; wireless communication is a key area of current study. Numerous application fields, including military surveillance, weather report forecasting, soil testing, crop forecasting, emergency medical treatment, etc., benefit from sensor communication. Lightweight nodes that make up wireless sensor networks receive environmental data such as air pressure, wetness, force, friction, location, sound, etc. and send that information to the base station (BS) for a specialized analysis. Because there is no one in charge of monitoring and controlling the whole sensor field, sensor nodes' limited power and processing capacity makes them more susceptible to network security breaches during communication. Numerous researchers have attempted to address the issue of sensor network security in the past using a variety of strategies, but the subject remains open since new attacks and other irregularities are discovered on a daily basis. We design a system to identify and prohibit wireless sensor networks using packet filtering approach to solve the security issue. To that end, the following objectives are defined to meet security requirements.
