Multi-path is a technique to increase the reliability of the internet connection in IP network. The implementation of this technique can be described as a host with two TCP paths work together, when one of them fails the other will back up the connection. Since TCP does not support multi-homing, the right term for this technique is multi-path. The fairness problem arises when multi-path host uses...
In face of heterogeneous RATs coexisting in next generation communication system, the network selection is related to Cooperative Radio Resource Management (CRRM) and QoS requirements of traffics and users' preference etc to give the best choice for the users. Based on the proposed MAC layer architecture which set Cooperative RRM manager, in this paper the Differentiated Traffics Relative Band Request...
Seamless vertical handover is one of the major challenges toward seamless inter-networking between heterogeneous access networks. To perform seamless vertical handover even under bad radio conditions in network mobility (NEMO) environments, NEMO-SHO has been proposed as an IPv6 soft handover extension that allows packet bicasting via two different wireless links simultaneously. However, the performance...
The race to implement 4G (fourth generation mobile communication systems) is spiraling day by day. Researchers and vendors want to reap the benefits of this new technology. But migration to 4G is full of hurdles as 4G mobile communication systems hold great promise in supporting data transmission rates of upto 100 MB per second and providing wireless devices users with near-ubiquitous connections...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
