Many clustering routing protocols had been proposed which had rarely considered the network security issues so far. Most of the layer clustering key management methods does not consider the problem of key updating and cluster head being captured. Considering the probability of node being captured, particle swarm optimization algorithm was used to optimize the clustering of sensor networks. A dynamic...
Key management is the core to ensure the communication security of wireless sensor network. How to establish efficient key management in wireless sensor networks (WSN) is a challenging problem for the constrained energy, memory, and computational capabilities of the sensor nodes. Previous research on sensor network security mainly considers homogeneous sensor networks with symmetric key cryptography...
