Live streaming video has become one of the most popular P2P applications with its high-quality performance and playing effect. Since the real-time requirement, live streaming systems have to adopt an appropriate neighbor selection mechanism to realize effective content distribution. This paper takes PPLive which is a classic P2P IPTV system as the object to measure and analysis. We pay our attention...
In this paper we provide an architecture for Tactical Information Middleware for bandwidth constrained information management. We propose the ideas of rank-based data dissemination, and the use of a tactical information management query language. These ideas will deal with dynamic changes in bandwidth and explore opportunistic data dissemination. Thus, will lead to a cross layer design of a system...
Vehicular ad-hoc networks (VANETs) is a promising approach to the dissemination of spatio-temporal information such as the current traffic condition of a road segment or the availability of a parking space. Due to the constraint of the communication bandwidth, only a limited number of information items may be transmitted upon a vehicle-to-vehicle communication opportunity. Ranking becomes critical...
Identification of various P2P flows accurately is fundamental for network management. To obtain P2P flow information in real-time and low price, a distributed extensible architecture for P2P flows identification called DEAPFI is proposed. DEAPFI decentralizes functions of flow identification and statistic on different PC, which is composed of identification system (IS) and statistic system (SS) respectively...
In this environment each mobile peer has a local database that stores and manages a collection of reports (where each report is a product record, or a coupon), and all the local databases maintained by the mobile peers form a mobile e-commerce (or, more generally, a mobile P2P) database. Queries on this database are posed by potential customers, and they search for coupons and products pertaining...
Peer-to-peer data dissemination in a mobile ad-hoc environment is characterized by three resource constraints, including energy, communication bandwidth, and storage. Most of the existing studies deal with these constraints separately. In this paper we propose an algorithm called RANk-based dissemination (RANDI), which provides an integral treatment to the three constraints. The contribution is in...
We examine data dissemination in mobile peer-to-peer networks, where moving objects communicate with each other via short-range wireless technologies such as IEEE 802.11 or Bluetooth. Given the memory and bandwidth/energy constraints at moving objects, the ideal mobile peer-to-peer dissemination method is for each moving object to store and transmit only the reports that are new to other objects encountered...
