“…Mechanisms for "micro-charging" for content and information over IMS networks have been proposed by the authors. [15] as has the generation of charging schemes for composed IMS services [16], this being relevant in situations where there are multiple providers of context information or context inference. A business could buy a package of relevant (filtered) contextupdates for a group of subscribers who are employees of the business, which can then be used to update the businesses information systems.…”

Abstract-Pervasive mobile communication is set to be greatly enhanced by the development and deployment of miniature mobile base stations, suitable for workplace or home. These base stations, known as Femtocells and Picocells, connect to traditional broadband connections, to offer greatly improved 3G communications to mobile handsets. Developing an architecture that allows for targeted applications to be developed for end users of these enhanced mobile networks is of great importance. Examining how contextual data, extracted from these mobile networks, can be used to make inference and provide benefit to end users is both a technical and sophisticated challenge to be discussed in this paper.

“…P2P live streaming has been a thoroughly researched topic with many contributions from the scientific community [1], [2], [4], [8], [10], [11], [13], [14], [23], [24], [25] that lead to many commercial systems such as [16], [17], [18], [19]. The main objective of these systems is the uninterrupted stream delivery with high QoS and Quality of Experience (QoE) with respect to conventional content distribution systems.…”

“…Nevertheless, when these systems are deployed in real conditions, as commercial or operational P2P live streaming systems [16], [17], [18], [19], they fail to achieve the reported performance and stability. Even an inexperienced user can notice high latencies, instability and low bit rates of the delivered video stream.…”

“…Moreover, numerous recent publications prove that the P2P concept has been gaining much attention (e.g., Christakidis et al, 2011;Couto da Silva et al, 2011;Kim et al, 2009;Ramzan et al, 2011;Suri et al, 2010;Terzo et al, 2011;Zhou et al, 2011). This follows mainly from the fact that in many cases the conventional client-server architecture faces various problems and limitations, including scalability (i.e., a growing number of users), diversity of new network applications, cooperation between many domains using various physical technologies, etc.…”

“…On the other hand, virtualization including P2P systems provides considerable network functionalities (e.g., diversity, flexibility, manageability) in a relatively simple way and regardless of the physical and logical structure of the underlying networks. Accordingly, various distributed applications employ the P2P and other network virtualization concepts (e.g., Christakidis et al, 2011;Couto da Silva et al, 2011;Kim et al, 2009;Ramzan et al, 2011;Suri et al, 2010;Shen et al, 2009;Zhou et al, 2011).…”

Recently, distributed computing system have been gaining much attention due to a growing demand for various kinds of effective computations in both industry and academia. In this paper, we focus on Peer-to-Peer (P2P) computing systems, also called public-resource computing systems or global computing systems. P2P computing systems, contrary to grids, use personal computers and other relatively simple electronic equipment (e.g., the PlayStation console) to process sophisticated computational projects. A significant example of the P2P computing idea is the BOINC (Berkeley Open Infrastructure for Network Computing) project. To improve the performance of the computing system, we propose to use the P2P approach to distribute results of computational projects, i.e., results are transmitted in the system like in P2P file sharing systems (e.g., BitTorrent). In this work, we concentrate on offline optimization of the P2P computing system including two elements: scheduling of computations and data distribution. The objective is to minimize the system OPEX cost related to data processing and data transmission. We formulate an Integer Linear Problem (ILP) to model the system and apply this formulation to obtain optimal results using the CPLEX solver. Next, we propose two heuristic algorithms that provide results very close to an optimum and can be used for larger problem instances than those solvable by CPLEX or other ILP solvers.
