Abstract

The next generation communication environment consists of various wireless access networks with distinct features thatare configured as an overlay topology. In the network environments, the frequency of handovers should be minimized and the error propagation should be solved in order to provide high-quality multimedia services to mobile users. Therefore, we propose an performance enhancement approach,based on mSCTP, that provides high-quality multimedia services to mobile users by ameliorating the error-propagation problem. We utilizes the following four functions: 1) the separation of transmission paths according to the types of frames, 2)retransmission strategy to minimize the loss rate of frames, 3) Foced vertical handover execution by utilizing bicasting, 4) using the stability period in order to reduce the effect of the ping-pong phenomenon. The simulation results show that the proposed approach provides seamless multimediaservice to mobile users by achieving error resilience.
