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...
The advancement in wireless networking technologies and portable devices has motivated the explosive interests in heterogeneous wireless environments. However, the mobility and diversity of both devices and users bring new challenges for the design of mobile Internet applications. Seamless mobility support has always been one of the key problems. In this paper, we study context-aware adaptation for...
In realistic mobile heterogeneous environment, the quality perceived by user is variable and dependant on following major factors: available bit rate variation, packet loss and latency. Even though QoS management is enabled in most modern telecommunication systems, it does not ensure the actual end-user perceived quality of service level. Therefore, to make sure that operator follows SLA provisions,...
In this paper fast mobile multicast mechanism based on IEEE 802.21 MIH (Media Independent Handover) is proposed. We solve long multicast handover delay time caused by L3 movement detection mechanism of the existing mobile multicast methods. The proposed architecture adopts multicast manager concept to MIH framework in order to efficiently perform mobile multicast handover, and adds the new MIH messages...
Mobility is a key research area in next generation networks. With operators moving towards fixed mobile convergence where various access networks connect to a common IP centric core, users are being offered a plethora of ways in which to connect to this core. Although there has been a rise in the types of access technologies, we have not seen one access technology prove to be useful in all situations...
