A Network Selection Algorithm Based on Reputation Model

In order to deal with the problem of access network selection in the next generation wireless networks, it is necessary to develop an adequate model for its selection. This paper presents the proposal of optimal network selection algorithm in wireless heterogeneous environment that is based on reputation model. It not only considers the users´ preferences, but also the results of network admission. And the simulation results show that the algorithm proposed in this paper can effectively reduce the energy consumption, have lower packet loss rate and balance the load of candidate networks.
