Key management scheme based on unital for wireless sensor networks
LI Lanyin · Computer Engineering and Applications Journal · 2015
To tackle the problems of poor network scalability, low network connectivity and large storage overhead to the existing wireless sensor networks, based on the clustering wireless sensor networks, a unital-based new key pre-distribution management scheme which provides good network scalability also has a high network connectivity is proposed. The scheme uses a third-party service nodes as the base station to complete the communication between the cluster head and uses the new scheme to complete the communication between the cluster head and the cluster member. The analysis and calculation results verify the effectiveness of the new management scheme compared to existing schemes at equal network size.
