Promising Key Management Schemes in Wireless Sensor Networks: A Review
Kamal Kumar, R. B. Patel, Anil Kumar Verma · 2009
Recent advancements in wireless communication and microchip techniques have accelerated the development of wireless sensor networks (WSNs). Key management in WSNs is a critical and challenging problem because of the inner characteristics of sensor networks: deployment in hostile environments, limited resource and ad hoc nature. In this paper we investigate the constraints and special requirements of key management in sensor network environment, with some basic evaluation metrics.
