Topic: An investigation of large scale challenges with live video streaming over Wi-Fi access networks
Due to growing demand for wireless access technology (802.11 stan
dards), high capacity multimedia transmission over wireless pose a chal
lenge, by taking note that video streaming has gained enormous popularity
and is accountable for a large fraction of current internet traffic.In order
to have a satisfy video transmission wireless network especially when it
comes to large scale user and roaming intensity, many requirement must
Large throughput and minimum delay are the significant requirements
to keep the transaction stable and seamless, moreover jitter is another
important factor that can result in degradation and quality of received
video. To achieve seamless live video stream and high level of quality of
service (QoS) and quality of experience (QoE) different technologies must
be studied, such as video encoding/decoding platform, transmission tech
nology (unicast/multicast) mobility models and efficient handoff method.
These issues are addressed in this project.
During this work, several experiments are done in NS2 simulator to study
the impact of increasing in number of users on the QoS parameters such
as delay, throughput and jitter, while an H.264 SVC video stream id
transmit over the wireless network in both multicast and unicast manner.
Also, the effect of Random Waypoint and Gauss-Markov mobility model
on the delivering performance studied. The experiments tested during
movement inside an AP coverage area as well as movement to new AP
domain (Handoff). Hierarchical Mobile IPv6 is the protocol used in the
simulation, in order to have a faster handoff and reduction in the amount
of signaling load.
