Wireless Mesh Networks (WMNs) have been widely deployed as a new communication paradigm that can provide innovative services for a community (neighborhood, campus, etc.). WMNs are capable to provide both delay-sensitive services such as Voice over Internet Protocol (VoIP) and delay-insensitive services such as peer-to-peer file sharing. Network routing protocols in WMNs often employ the minimum-hops...
Flooding search is a basic searching scheme for unstructured peer-to-peer networks. This technique produces exponentially redundant messages in each hop. Subsequent growths of redundant messages will limit system scalability and will cause unnecessary traffic in network areas. To improve this searching scheme and reduce redundant messages, this paper proposed a novel algorithm (SmoothFlood) which...
Triple-play services and P2P IPTV have not only led to an increasing demand for bandwidth in broadband access networks, but also to the need for new service delivery architectures. The choice of an appropriate architectural approach and sizing model for the aggregation network is studied in this paper through cost optimization models, which encompass aspects of non-stop delivery, service flexibility,...
The use of broadcast TV channels is growing considerably so that the number of users (scalability) and the need to manage traffic (bandwidth) are challenges for network design and dimensioning. Broadcast and live channels show strict requirements to operate on a continuous basis in content distribution scenarios in terms of delay, huge demand of bandwidth and characterized by very dynamic variations...
Peer-to-peer (P2P) technologies rapidly attracted people and had a big success for file sharing applications as well as for other kinds of applications such as voice and now video streaming applications. But this success has also an impact on the physical networks, which become more loaded and could lead to a point where the quality of P2P services may decrease. Therefore it is necessary to study...
