In order to promote the participation of more actors (both Wi-Fi providers and users) and the success of this kind of emerging solutions is important to satisfy the expectations that the user has regarding the network and the services, increasing the Quality of User Experience (QoE). As one might expect the wireless nature of the Collaborative Wi-Fi Networks imposes a set of challenges those have to be addresses in order to guarantee the QoE that the users are expecting. In this talk, we outline research challenges encountered to improve the overall experience of the user of Collaborative Wi-Fi Networks. Our approach is to study the effect of the user´s perception firstly modifying the way that the user picks the Access Point during the Wireless Association. We highlight how an association based on the selection of the Access Point with the largest RSSI does not guarantee the satisfaction of the expectations of the users. Second, we explain how avoiding duplicate data packets downloaded in the same BSS, improving the throughput of the BSS and the QoE. /fileadmin/papers/2011/2011-Lora-QoMex-Abstract.pdf Online Third International Workshop on Quality of Multimedia Experience - QoMEX 2011, Mechelen, Belgium Mechelen, Belgium Third International Workshop on Quality of Multimedia Experience - QoMEX 2011 September 7 - 9, 2011 Abstract en 978-1-4577-1335-4 1 Mónica AlejandraLora Girón inproceedings 2011-ipsn-alizai-pad 2011 4 fileadmin/papers/2011/2011-ipsn-alizai-pad.pdf Online ACM

While such means are essential to overcome distances, using infrastructure services for location-based services may not be desirable. In this paper, we analyze a fully distributed variant of an ephemeral content sharing service, solely dependent on the mobile devices in the vicinity using principles of opportunistic networking. The net result is a best effort service for floating content in which: 1) information dissemination is geographically limited; 2) the lifetime and spreading of information depends on interested nodes being available; 3) content can only be created and distributed locally; and 4) content can only be added, but not explicitly deleted. First we present our system design and summarize its analytical modeling. Then we perform extensive evaluation for a map-based mobility model in downtown Helsinki to assess the operational range for floating content, which, at the same time also validate the analytical results obtained for a more abstract model of the system. https://www.comsys.rwth-aachen.de/fileadmin/papers/2011/2011-percom-vaegs-floatingcontent.pdf Online IEEE
