Wireless Sensor Networks: Security Issues, Challenges and Solutions

The emergence of wireless sensor networks (WSN) as one of the dominant technology trends in the coming decades has posed numerous unique challenges to researchers. The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance in future. The inclusion of wireless communication technology also incurs various types of security threats. The intent of this paper is to investigate the security related issues, the challenges and to propose some solutions to secure the WSN against these security threats. While the set of challenges in sensor networks are diverse, this paper focus only on the challenges related to the security of Wireless Sensor Network. This paper begins by introducing the concept of Wireless Sensor Network (WSN). The introductory section gives brief information on the WSN components and its architecture. Then it deals with some of the major security issues over wireless sensor networks (WSNs). This paper also proposes some of the security goal for Wireless Sensor Network. Further, as security being vital to the acceptance and use of sensor networks for many applications; I have made an in depth threat analysis of Wireless Sensor Network. Lastly it proposes some security mechanisms against these threats in Wireless Sensor Network. KeywordsChallenges, Issues, Security, Wireless Sensor Network (WSN)
