On the multi-objective stochastic optimal route of a mobile agent in multi-provider network QoS with uncertain parameters

Abstract

In order to determine an optimal route, the network performance and cost of many network providers must be compared when end-user visit the content provided by content provider under the certain QoS constraints in multi-provider network. The correlative network information is collected by mobile agent. The delay and cost between any two nodes of network is set to be random variables. The minimum model with expectation of cost and delay value is presented in a stochastic network. The optimal solution of mobile agent route from service provider to content provider is computed and using genetic algorithms. In a case scenario of data simulation, the result obtained show operation effectiveness of the above approach.
