Abstract
The objective of this thesis is to design and implement a cross-layer packet striping framework for video streaming in heterogeneous wireless networks.
Due to the great progress of processing speed of integrated chips and cost down of small size color screens in recent years, mobile devices today are able to display color video clips well and to connect to various wireless networks through different network interfaces. With those abilities the users always want to stream video on them. Traditional video streaming framework can always uses only one network interface. However due to the unstable characteristics of wireless transmission channels, the quality is not well after all.
In order to overcome this problem, this thesis tries to use the available links on mobile devices spontaneously to improve overall wireless networks reliability. A packet striping framework is designed to schedule the video packets to the links to provide better video streaming quality.
However, some resources such as communication fee or battery power on mobile device are valuable to users. To increase the feasibility of the packet striping framework, the usage of resource is also considered while designing the framework. Finally, simulations are conducted on NS-2 to show the effectiveness of the proposed cross-layer packet striping framework.
