Deployment of video communication services over mobile ad hoc networks faces numerical obstacles since the networks are characterized by limited and unpredictable bandwidth. Following the tenet of service-orientation, this study proposes a cross-layer design for fine-grained adaptive transmission of real-time video over time-varying channels. Specifically, the sender accurately estimates the current...
Multimedia exchange within a Vehicular Ad Hoc Network (VANET) may be facilitated by exploiting the peer-to-peer (P2P) paradigm. Urban VANETs are characterized by restricted vehicle mobility, driver actions, and bunching at obstacles, leading to wireless interference and broken links. Similarly P2P communication relies on distributed sources which are intermittently available. However, routing packets...
In Wireless Mesh Networks (WMNs), users can enjoy the real-time video streaming service anytime and anywhere through the service. Compared to the client/server model, the P2P (Peer-to-peer) approach is more suitable for video streaming applications because of its efficient usage of network resources. However, the multimedia applications are very sensitive to delay time and the performance of packets...
There has been a spate of interest in wireless mesh networks in recent years. The reason behind such an upsurge of interest is that wireless mesh networks are seen as enablers of ubiquitous broadband access applications such as the Internet. Moreover, wireless mesh networks provides benefits such as ease of installation, cost effective deployments, a high level of scalability in coverage area and...
Video streaming over wireless ad-hoc networks requires appropriate routing and rate allocation mechanisms that efficiently adapt to the characteristics of such environments. The special features of ad-hoc networks also motivate us to introduce proper mechanisms in video coding, error concealment and various related areas. In this paper, we propose a framework for video streaming over wireless ad-hoc...
