Security Issues and Challenges in Wireless Sensor Networks: A Review

Abstract: Wireless sensor network is the rising technology for sensing and performing the various tasks. Sensors are small device having memory, power and processing chip that makes it processing device. These WSNs have various purposes in many fields like Healthcare, industry, military, smart homes, etc.. WSNs have more advantages over wired networks. These systems are probably going to be made out of hundreds, and a large number of modest sensor nodes, working independently. Though there are several advantages of wireless networks, they are prone to security issues. Security became a major concern for wireless sensor networks because of the wider application. So, this paper addresses the security issues and challenges of WSNs in various layers of the communication protocols.
