Multiobjective Optimal Secure Routing Algorithm using NSGA-II

Integrating security metric into QoS framework is a new strategy in secure routing. Existing QoS framework use only one security metric to describe the link security. Aiming at the deficiency of existing secure routing, we propose a novel strategy which employs multi-security metrics as QoS parameters to achieve more secure route. In our strategy, security metric is combined with other general QoS parameters in differentiated service and then form a multiobjective, multiconstraint secure model. Since the model will be known as a NP complete problem, we introduce nondominated sorting genetic algorithm II to solve the problem. We call the proposed strategy as MOSRA (multiobjective optimal secure routing algorithm). Finally, the simulation results demonstrate that the performance of our proposed algorithm.
