We investigate streaming over multiple links. A file is split into small units called chunks that may be requested on the various links according to some policy and received after some random delay. After a start-up time called pre-buffering time, received chunks are played at a fixed speed. There is starvation if the chunk to be played has not yet arrived. We provide lower bounds (fundamental limits)...
In order to satisfy the increasing demands of wireless mobile communications, Long Term Evolution (LTE) has been proposed as an all-IP-based network to bring higher peak data rates and better spectral efficiency. As one of the sub-layers of LTE, Radio Link Control (RLC) layer is likely to congest or overflow due to handover or undesirable channel condition. In this paper, based on Random Early Detection...
There has been a lot of research focusing on optimizing the Long Term Evolution (LTE) networks performance. A large part of this research focused on how to optimize the LTE radio interface to efficiently distribute the scarce radio resources among the LTE users. Since LTE offers a diverse amount of services, the Quality of Service (QoS) differentiation is a major challenge. QoS is handled in LTE at...
The Long Term Evolution (LTE) may provide ubiquitous mobile broadband services with all IP architecture, however, the quality of service (QoS) of LTE systems is seriously affected by the network congestions, packet losses, jitters, latencies and other QoS issues in all IP networks. Thus it is valuable to investigate and design efficient resource scheduling algorithms to improve the performance of...
