Practical overview of security issues in wireless sensor network applications

Wireless sensor networks are widely used in applications to monitor and communicate data. Even though the wireless sensor networks have been broadly used in critical applications, security and privacy issues are major concern. The attackers can gain considerably easy access into a wireless sensor networks and inject malicious data. Wireless sensor networks are considered to be vulnerable to the attacks. The aim of this research is to review the practical scenarios and applications, expose the security vulnerabilities and issues associated with wireless sensor networks specific to applications. The need for research in this area is high since it provides a broad scope to investigate problems and issues in current applications.
