Research on essential nodes in pairwise key-sharing graph of sensor networks
WU Jiayin · Computer Engineering and Applications Journal · 2010
Available mechanisms on pairwise key establishment will make possible a number of isolated connected components in sensor networks,due to random deployment of sensor nodes and dramatic degree of network scale.Based on multi -nodes authentication trust model,a kind of essential nodes that will make components interconnection is analyzed.Also pairwise key establishment protocol for those nodes is presented.Compared with widely accepted pairwise key establishment,figures show that the presented protocol can achieve interconnection of components effectively,with little loss on resilience of sensor nodes in the network.
