In this paper, we consider the wireless broadcasting scenario with a source node sending some common information to a group of closely located users, where each link is subject to certain packet erasures. To ensure reliable information reception by all users, the conventional approach generally requires repeated transmission by the source until all the users are able to decode the information, which...
With the ever increasing number of mobile devices and their computational capacity in terms of processing, storage and software, the use of smart devices is being employed each time more not only for basic use and entertainment and social networking but also for work. Besides this added value to use smart devices for work at individual level, the interest is of course to explore the use of such devices...
P2P technologies have been considered as one of the most disruptive Internet technologies in achieving fully decentralized and efficient communication in distributed systems. Indeed, the nature of the direct communication among peers in the system, being these machines or people, makes possible to overcome the limitations of the flat communications through email, newsgroups and other forum-based communication...
Today, peer-to-peer (P2P) traffic consumes the largest fraction of network bandwidth. The files shared by P2P communications are mostly copyright protected, and there are issues related to Quality of Service (QoS) support and billing of P2P traffic. Hence, scalable and accurate detection of peer-to-peer (P2P) traffic is a significant problem for network service providers. Flow-based detection methods...
In this paper, we propose an innovative solution for positioning determination in 4G wireless networks by introducing the ad-coop positioning system (ACPS). The ACPS is supported by a hybrid cellular ad-hoc architecture, where the cellular network has a centralized control over the ad-hoc connections among pairs of mobiles. Specifically, P2P communications are exploited in a mesh fashion within cellular-established...
