Security management in Wireless Sensor Networks

Security management in Wireless Sensor Networks This paper aims to describe the characteristics of Wireless Sensor Networks (WSNs), challenges in designing a resource-constrained and vulnerable network and address security management as the main issue. The work begins with discussion on the attacks on WSNs. As part of protection against the attacks faced by WSNs, key management, the primary requirement of any security practice, is detailed out. This paper also deals with the existing security schemes covering various routing protocols. The paper also touches security issues concerning heterogeneous networks.
