Particle Swam Optimization Based Technique for Node Capture Attack In Wireless Sensor Network

Abstract

To improve the attacking efficiency of node capture attack, we designed a Node Capture A ttack Algorithm based on Particle Swarm Optimization (NCPSO). NCPSO takes multiple objectives into consideration, that are: Maximum Node Participation, Maximum Key Participation and M inimum Resource Expenditure to find a set of optimal nodes using PSO that satisfies all the objectives, destroys maximum portion of the network and provides higher attacking efficiency at least attacking cost. The simulation results manifest that NCPSO can provide reduced attacking cost (resource expenditure) than Matrix Algorithm (MA) so the attacking efficiency of NCPSO is considerably improved
