Abstract—In order to enable fast deployment of new emerging services over multimedia radio networks, it is important to design an efficient service-based platform with necessary traffic management. Among the solutions, mobile network platforms must be able to answer efficiently and on time to the expectations of the users through dynamic adaptation of the architecture to answer the demands on time and with the minimum cost. it runs dynamically by modifying services features according to subscribers’ requirements, network capacity and QoS parameters. In this paper, we propose a new service oriented framework for wireless radio networks, based on a hybrid algorithm in which we adopt an adaptive approach toward optimal traffic distribution. It is inspired from methods from graph theory, operational research, network optimization and load balancing work.We use media streaming for “Emergency Services” as an example to illustrate how such a service can be provided. Performance evaluation shows that the platform can substantially improve the conventional approach and achieves similar performance than the one obtained by hybrid scheme. We present in this paper some results which show the congestion status of servers and links obtained from the simulation platform.
