The need to respond to congestion and channel loss over not one but two wireless links is an impediment to video streaming between one mobile user device and another via an intervening IP network. The result can be poor wireless channel utilization and interruptions to the streaming process. This paper proposes that multi-connection streaming will avoid the need for application-specific cross-layer...
In order to bear reliable end-to-end services transmission in insecure IP network, SCTP as the transport protocol of the next-generation Internet was proposed. The performance of SCTP has been improved in related literature; however, they optimized it based on a single or a few parameters, which is lack of a comprehensive consideration in correlation parameters. In consideration of real-time and the...
Multimedia applications have been the key driving force in converging fixed, mobile and IP networks. A major hurdle in the realisation of this convergence is obtaining Quality of Service from a heterogeneous, best-effort service network. Interactive voice requires strict bounds on delay, jitter and packet losses, video adds significant bandwidth requirements to the network, while Internet only makes...
As advanced integrated network architecture, "cognitive radio technologies," which aim to improve the spectrum efficiency, have been studied. In the cognitive radio networks, each node recognizes radio conditions, and according to them, optimizes their wireless communication routes with the integration of the heterogeneous wireless media not only by switching over them but also aggregating...
