Wireless mobile multimedia communications are being greatly increased in the number of users, diversity of applications and interface technologies. Future mobile based Internet will accommodate various wireless technologies and also will need to provide sufficient end-to-end QoS (Quality of Service) mechanism to provide enhanced user's satisfaction. In this paper, we propose a new adaptive end-to-end...
Relayed transmission is an interesting topic in cooperative diversity. Some researchers propose power allocation schemes for relayed transmission by only considering transmission through a fixed relay node. In our paper, we analyze a relayed transmission through a mobile relay node. We build up a transmission system model and determine the long term distribution characteristics of the movement of...
Most important frameworks supporting mobile communications are not capable of meeting real-time application requirements due to the service degradation appearing during the handover process. This degradation is noticed by the application as an excessive service blocking time and a non-negligible packet loss rate. The reasons of this degradation are: slow procedures for address allocation, too much...
