Security Challenges in Wireless Sensor Network: Current Status and Future Trends

WSNs have several applications in the military, the environment, and medicine. These applications often involve tracking sensor data, such as the actions of enemies on the battlefield or the position of people within a structure. As a result, Wireless sensor network (WSN) security is of prime concern. However, WSNs face many challenges, including low computing power, low memory, tight power supplies, vulnerability to physical detection, and unreliable wireless communication paths. These problems complicate the security of WSNs. This paper is an overview of the security of WSNs. This paper explains the number of security-related issues related to WSNs, including secure routing methods, various security attacks, etc. Then, the limitation of security in WSNs is examined and contrasted as challenging. Also, the pros and cons of multiple WSN security protocols are explained. For each open research question in each sub-area, conclusions are drawn regarding possible future study directions on safety in WSNs.
