Children and Peer-to-Peer Risks in Social Networks: Regulating, Empowering or a Little Bit of Both? KU Leuven
Social networking services (SNS) are an important part of many children and teenagers' media use. As they communicate and share content by means of these services, minors may also engage in more risky behaviour, leading to reciprocal harassment which may blur the lines between victims and offenders to a greater extent than in the offline world. However, due to the specific nature of SNS, the use, and especially the implementation and enforcement ...
On the computational complexity of peer-to-peer satellite refueling strategies KU Leuven
We revisit the peer-to-peer on-orbit satellite refueling problem, in which the maneuvering satellites are allowed to interchange their orbital positions. We show that the problem is computationally hard by reducing it to a special case of the three-index assignment problem. On the positive side, we show that the size of instances in practice is such that a state-of-the-art integer programming solver is able to find globally optimal solutions in ...
Evaluation framework for adaptive context-aware routing in large scale mobile peer-to-peer systems KU Leuven
The proliferation of novel wireless network technologies creates new opportunities for complex peer-to-peer information dissemination systems. A key challenge that remains in this area is how to select the best algorithms and protocols to communicate effectively on a large scale. In this paper, we focus in particular on large scale mobile networks where effectiveness depends on the requirements of the application at hand and on the context of ...
Optimizing information dissemination in large scale mobile peer-to-peer networks using context-based grouping KU Leuven
Nowadays novel embedded computing devicesenable vehicles to form large scale mobile peer-to-peernetworks in which they can assist each other to improve their driving experience. Therefore context-aware communication is considered to be vital for inducing inter-vehicular intelligence between groups of vehicles with similar interests. However, traditional network addressing schemes are not well suited for group-based communication in large scale ...
Examining the Use of Peer-to-Peer Networks from an Activity Perspective KU Leuven
The convergence of Internet and TV, i.e., the Over-The-Top TV (OTT TV) paradigm, created opportunities for P2P content distribution as these systems reduce bandwidth expenses for media companies. This resulted in the arrival of legal, commercial P2P systems which increases the importance of studying economic aspects of these business operations. This chapter examines the value networks of three cases (Kontiki, Zattoo and bittorrent) in order to ...
Peer-to-Peer Content Distribution and Over-The-Top TV: An Analysis of Value Networks KU Leuven
The convergence of Internet and TV, i.e., the Over-The-Top TV (OTT TV) paradigm, created opportunities for P2P content distribution as these systems reduce bandwidth expenses for media companies. This resulted in the arrival of legal, commercial P2P systems which increases the importance of studying economic aspects of these business operations. This chapter examines the value networks of three cases (Kontiki, Zattoo and bittorrent) in order to ...
Indoor positioning in peer-to-peer networks University of Antwerp
We present two algorithms for indoor positioning in peer-to-peer networks. The setup is a network of two types of devices: reference devices with a known location, and user devices that can determine distances to reference devices and each other. We present two algorithms for positioning estimation in such a peer-to-peer network. The first one is purely geometric and reduces determining the best estimate for the position of a device to a least ...
