This paper proposes efficient analytical models to dimension the required transport bandwidths for the Long Term Evolution (LTE) access network for the elastic Internet traffic (which is carried by the TCP protocol). The dimensioning models are based on the use of Processor Sharing queuing theory to guarantee a desired end-to-end application QoS target. For validating the analytical dimensioning models,...
Using the application of bluck data transfer, we investigate the performance of QoS-satisfied pathover for transport layer mobility scheme such as mSCTP in FMIPv6 envirmonment. We find that existing scheme has some defects in aspect of pathover and throughput. Based on this, we make a potential change to mSCTP by adding QoS-Measurement-Chunk, which is used to take into account information about wireless...
The presence of delay-sensitive traffic in QoS-aware MANETs (mobile ad-hoc networks) results into increased TCP spurious timeouts, thus wasting their scarce bandwidth. Furthermore, the different dynamics used by a routing protocol in discovering and maintaining routes have a significant impact on TCP and MANETs in general. In this paper, we investigate the combined effect of contention- induced spurious...
Streaming video would become a popular form of transferring video over next-generation wireless overlay networks. As transport protocol for streaming video, TCP- friendly rate control (TFRC) is generally used. Using both TCP congestion response function and current network conditions, TFRC adjusts transmission rate so as to achieve maximum TCP-friendly throughput. However, TFRC is less responsive...
Under the upcoming 4G network, mobile devices will have to handle multiple interfaces. Each network mechanism has its merits, such as WiFi's high speed and the long transmission range of High Speed Download Packet Access (HSDPA), but managing a combination of different interfaces during a hand-off procedure presents new challenges for next-generation networks because the network environment will continue...
