TMSNSGA: Trust Management System using Non dominated Sorting Genetic Algorithm

Grid technology has emerged as development of distributed frameworks mostly centered around remote sharing and access to computational resources in an effectively transparent, reliable and secure way. To provide practical solutions to overcome the drawbacks and limitations of both the technologies, it is required to hybridize Grid technology and Mobile technology to form one of the most assuring futuristic technologies, Mobile Grid Computing, in recent years. Security has been regarded as one of the critical issues in the field of in the mobile grid system due to its open, dynamic, heterogeneous and distributed nature. A secure mobile grid system can be achieved by implementing different security services at different levels. In this paper, we propose one of the most essential security service based on Trust Management. Trust Management problem in the mobile grid system is a multiobjective nonlinear optimization problem with a set of constraints. In this paper, we have proposed a trust management system based on the Nondominate Sorting Genetic Algorithm-II (NSGA-II) for solving the problem of trust management. Experimental results show that the proposed approach is more efficient than the existing trust management systems.
