Security protocols for wireless sensor networks

摘要

As Sensor networks are being used in remote environment monitoring, healthcare, machine automation, security of these networks is becoming a central concern. Till now main concern was to make sensor networks useful and deployable and little emphasis was placed on security. This paper analyses security issues and vulnerabilities in wireless sensor networks. The paper gives an overview of various security protocols used for wireless sensor networks and finally a comparison is done for the various security protocols available.
