LASCNN is a Localized Algorithm for Segregation of Critical/Non-critical Nodes [1] The algorithm worked on the principle of distinguishing between the critical and non-critical nodes for the network connectivity based on limited topology information [2]The algorithm find the critical nodes with the partial information within a few hops. [3]

This algorithm can distinguish the critical nodes of the network with high precision, and the accuracy can reach 90%. The accuracy of this algorithm can reach 100% when identifying non-critical nodes [4] The performance of LASCNN is scalable and quite competitive compared to other schemes [5]

Pseudocode

The LASCNN algorithm establishes k hop neighbor list and a duplicate free pair wise connection list based on k hop information. If the neighbors are stay connected then the node is non critical [6][7]
