Both user mobility and the nature of multimedia traffic are taken into consideration to design the adaptive resource allocation scheme, which consists of call admission control, resource reservation and bandwidth adaptation for real-time video/audio applications, as well as scheduling for non-real-time data services.Abstract:
Next-generation wireless communication networks aim at supporting multimedia services. It is a challenging problem to efficiently allocate limited and varying network resources in the wireless communication networks to a variety of multimedia services with different characteristics and requirements. In this paper, we extensively investigate the adaptive resource allocation for multimedia services in a wireless network environment. Both user mobility and the nature of multimedia traffic are taken into consideration to design our adaptive resource allocation scheme, which consists of call admission control, resource reservation and bandwidth adaptation for real-time video/audio applications, as well as scheduling for non-real-time data services. Simulation results show the strength of our proposed adaptive scheme.read more
