SECURITY CONCERNS IN WIRELESS SENSOR NETWORKS

Due to inherent limitations in wireless sensor networks, security is a crucial issue. While research in WSN security is progressing at tremendous pace, no comprehensive document lists the security issues and the threat models which pose unique threats to the wireless sensor networks. In this paper we have made an effort to document all the known security issues in wireless sensor networks and have provided the research direction towards countermeasures against the threats posed by these issues.
