Vehicular Ad-hoc Networks (VANETs) has witnessed significant attention from academia and industries, due to the growing number of applications and devices focusing on safety and efficiency in transportation. Video Streaming in Vehicular Communication (VSVC) presents interactive real-time view of an emergency incidence on roads. On-board unit of vehicles are utilized for streaming real time video of...
The purpose of this research is to address the issue of enhancing the Quality of Service(QoS) in IP networks, to make it more optimal in a given network of networks using a novel approach. In this approach, QoS is provided to the packet even when the packet crosses its access network into the backbone. It proposes a new design or set of features in the routers which maps and translates the QoS provisioning...
Software Defined Networking (SDN) is a promising technology for future internet applications through decoupling the data and control planes of computer networks. Enabling the development of application specific routing algorithms, the separation fosters the performance of internet applications. On the other hand, Application Layer Traffic Optimization (ALTO) provides network related information such...
Media streaming is the killer application in current Internet. There are a variety of media streaming techniques in today's Internet, such as RTSP, HTTP live streaming and Adobe Flash etc. HTTP live streaming (HLS) is a popular and most promising technique as the protocol is based on the Internet workhorse protocol i.e. HTTP, and supported by HTML5 and mobile platform. Most of these media streaming...
Video capture and transmission play an important role in mobile ad hoc network (MANET) applications, and the routing protocol has vital impacts on the design of network performance. In this paper we designed and achieved an embedded video capture and transmission system which used an improved routing protocol AODV-SBR (AODV-simple backup route). The results indicated the video transmission system...
It is widely acknowledged that the IPv4 address space will be close to exhaustion within the next few years, and the future growth of the Internet increasingly depends on the timely deployment and availability of IPv6. Both the Internet Corporation for Assigned Names and Numbers (ICANN) and the Australian Government have recently issued statements pushing for the adoption of IPv6. This paper reports...
Three applications in wireless networks where model-free stochastic learning is applicable, are discussed. The learning based optimization problems are formulated and simulation results are presented. Some open issues are also discussed.
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
