A Key Management of Wireless Sensor Networks for Telemedicine Care

This paper introduces a key management of wireless sensor networks for hierarchy of telemedicine care, which is composed by q-Composite random key distribution and the idea of Hyperball-based key management. It makes full use of independence and association between collection sensors. Analysis shows this management has advantages in lower cost of calculation and communication, higher update efficiency, less storage and is applicable for telemedicine care networks.
