IP multicast has proved to be the best approach for large scale multimedia communications enhancing video transmissions for applications like IPTV, video conferencing or other best-effort real-time audio/video applications. IP multicast connectivity, unfortunately, relays on certain network technologies and protocols and is present only in some areas of the Internet, while the majority of hosts lack...
When supporting both voice and TCP in a wireless multihop network, there are two conflicting goals: to protect the VoIP traffic, and to completely utilize the remaining capacity for TCP. We investigate the interaction between these two popular categories of traffic and find that conventional solution approaches, such as enhanced TCP variants, priority queues, bandwidth limitation, and traffic shaping...
A home Internet gateway is the node that resides between a public network and a home network for computers to share Internet connections. To insert customized queuing and scheduling codes into the embedded Linux kernel is a way to make the Linux-based home Internet gateways support Quality of Service(QoS). It is desirable that the small Linux kernel adopts an efficient queuing and scheduling algorithm...
The Internet access from vehicular networks is gaining great interest from the research community. In fact, vehicles should be able to connect to the Internet and communicate with different networks through gateways. Guaranteeing safety on the roads is the main objective of vehicular networks. Safety applications need to collaborate with other types of services for efficient safety assurance. Consequently,...
Wireless mesh networks (WMNs) are an emerging architecture for multi-hop transmission where the nodes have relative fixed positions and communicate to the Internet through one or more gateways. Our goal is to maximize the network utilization by balancing the traffic load, while providing fair service and QoS guarantees to the users. In this paper, we provide an efficient method that elegantly balances...
In wireless mesh networks (WMNs) traffic is routed from mobile clients through a multihop wireless backbone to and from Internet gateways (IGWs). Because of their limited number, IGWs become the major traffic bottlenecks. The purpose of this work is to explore the benefits of introducing load-dependent routing metrics to increase WMN capacity and performance. We use weighted shortest path routing...
