With the rapid advances in wireless ad hoc networking and the dramatic growth in network-based video applications, there is an urgent need for content-rich video communications in ad hoc networks. However, it is a great challenge to support real-time video transport over such networks. Providing acceptable video stability in ad hoc networks is a demanding task for both the video encoder as well as...
A light-weight, smooth, and quick-responsible accessibility to contents are truly needed for a practical usage of the mobile video services. We research on and develop a new innovative mobile video technology, which utilizes pre-download, pre-fetching and asynchronous network streaming schemes. This paper describes its innovative mechanisms, especially an asynchronous streaming technique and an asynchronous...
In mobile ad hoc networks, the communication node always produces a great deal of routing control packets while performing the route discovery and maintenance, which seriously impacts the real-time video transmission quality. Therefore, we propose a new routing control packets limited forwarding (RCPLF) algorithm that can reduce the routing overhead of on-demand routing protocol. In our algorithm,...
In wireless ad hoc networks, there are great challenges of supporting real-time video transmission due to the impact of frequent link interruptions, collisions, and bandwidth limitations and so on. Based on the analysis of the multipath routing and congestion control strategy, we propose a dynamic congestion control based multipath routing protocol (DccMR). DccMR establishes and maintains redundant...
This paper presents a channel-aware video streaming method that does not only adjust dynamically the target bit rate according to the channel condition but also minimize the error propagation at handoff. The proposed method performs adaptive bit rate allocation (ABA) by using the carrier to interference and noise ratio (CINR) to reduce the packet loss ratio (PLR) without wasting the channel resource...
