Recently, Japan Aerospace Exploration Agency (JAXA) provides Quasi-Zenith Satellite System (QZSS), a regional satellite system covering East Asia and Oceania region. The objective of QZSS is to improve the availability as well as the performance of GNSS system. Besides navigation signals, QZSS also transmits L-band Experimental signal (LEX) for augmentation corrections including orbit and clock information...
Network providers are nowadays facing with a big question in allocating network resources due to the constantly increasing of Internet services. While the network resource is not unlimited, users always desire the best quality of experience (QoE) with the huge information exchange. Therefore, finding a justice of network resource allocation based on the user experience is mandatory. In previous studies,...
Recently, most peer-to-peer (P2P) applications ignore traffic costs at internet service providers (ISPs), and thus generate a large amount of traffic crossing ISPs or autonomous systems (ASes) on the Internet. To reduce the cross-ISP/AS traffic, the existing approaches introduce network-aware strategies in which a lot of modifications of P2P systems are required. In this paper, we propose a router-aided...

Recently, peer-to-peer has been becoming a promising architecture for developing video streaming services because it can reduce the bottlenecks and the load at the server side. However, P2P systems implement their own routing protocols on overlay networks, which are largely independent of the Internet routing. As a result, the traffic generated by P2P systems is immense and unpredictable. Controlling...
Recently, peer-to-peer (P2P) traffic is increasing rapidly in volume day by day. One of the main causes is that most of P2P applications including file sharing and streaming applications often form overlay networks for exchanging data that are oblivious to the underlay network topology. As a result, they generate a large amount of inter-domain traffic causing higher cost for internet service providers...
