A Modified MRSVP Scheme Based on Motion Prediction

With the increasing widespread use of wireless technologies, the need arises for QoS provisioning mechanisms for multimedia applications in wireless networks. However, QoS protocols designed for fixed network are not applicable in mobile networks. In this paper, we propose a modified MRSVP scheme based on motion prediction for mobile networks. The modified MRSVP scheme using the result of motion prediction to obtain the weighted target cells collection and using the collection to select the path of resource reservation. When lack of the network resources, using QoS negotiation and snatch the resources by the weight. Simulation results show that the modified MRSVP can improve the hit ratio of reservation and effectively ensures the QoS of mobile users.
