Their main objective is to solve the scalability issue of ad-hoc networks by grouping nodes into clusters. The challenge in MANETs for those clustering algorithms is to cope with the high node mobility which affects the stability of the cluster structures. Wireless mesh networks consist of a static backbone and a number of mobile nodes. In the backbone of a wireless mesh network the topology is relatively static. However, topology changes occur due to frequent link losses and temporary link instability. Due to the static nature of the backbone, mobility-based approaches are not suitable in this case. In this paper, we state the important aspects for stable clustering in wireless mesh networks with unidirectional links based on the investigation of a 45-node wireless mesh testbed. We analyze well-known clustering algorithms and their performance in a large-scale testbed. Finally, we propose a new clustering algorithm called Stable Link Clustering Algorithm (SLCA).}, url = {fileadmin/papers/2010/2010-lora-clustering-MESH.pdf}, web_url = {http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5683417}, misc2 = {Print}, publisher = {IEEE}, booktitle = {Proceedings of the IEEE Global Telecommunications Conference GLOBECOM 2010, Miami, USA}, event_place = {Miami, FL, USA}, event_name = {IEEE Global Telecommunications Conference, GLOBECOM 2010}, event_date = {6 - 10 December 2010}, language = {en}, ISBN = {978-1-4244-5636-9}, DOI = {10.1109/GLOCOM.2010.5683417}, reviewed = {1}, author = {Krebs, Martin and Stein, Andr{\'e} and Lora Gir{\'o}n, M{\'o}nica Alejandra} } @Inproceedings { 2010-lora-CoNEXTStudent-ELA-Workshop, title = {Experience Level Agreements in Wireless Metropolitan Area Sharing Networks}, year = {2010}, month = {11}, volume = {1}, abstract = {Nowadays, mobile wireless users are in constant demand of connectivity. Satisfying the connectivity requirements of the users requires a large amount of Access Points (APs) in order to enlarge the wireless service coverage. Wireless Metropolitan Area Sharing Networks (WMSN) are a low cost alternative that fulfill this high degree of user requirements. On WMSN certain places will experiment congestion when a large number of users are associated with the same device. For this reason, new mechanisms are required with the aim of satisfy the Quality of User Experience (QoE). The Experience Level Agreements (ELA) definition for WMSN is a formal way to characterize the requirements of the users and permits having measuring functions for this kind of network, which helps to improve the QoE.}, url = {fileadmin/papers/2010/2010-lora-agreements-WMSN.pdf}, web_url = {http://portal.acm.org/citation.cfm?doid=1921206.1921215}, misc2 = {Digital}, publisher = {ACM}, address = {New York, NY, USA}, booktitle = {Proceedings of the ACM CoNEXT 2010 Student Workshop, Philadelphia, USA}, event_place = {Philadelphia, PA, USA}, event_name = {Proceedings of the ACM CoNEXT 2010 Student Workshop}, event_date = {November 30 - December 03, 2010}, language = {en}, ISBN = {978-1-4503-0468-9}, DOI = {10.1145/1921206.1921215}, reviewed = {1}, author = {Lora Gir{\'o}n, M{\'o}nica Alejandra} } @Inproceedings { 2010-lora-algosyn-QoE-dagstuhl, title = {QoE in Cooperative Wireless Networks}, year = {2010}, month = {6}, volume = {1}, pages = {20}, abstract = {Cooperative Wireless Networks (CWN) have become an attrac- tive alternative for providing ubiquitous and inexpensive connectivity for the mobile users.

In a CWN, some hot-spot areas may experience the problem of sporadic congestions. The appearance of this localized congestion adversely impacts the network performance in terms of effective throughput, leading to a Quality of User Experience (QoE) degradation. The challenge then is how to ensure the QoE for the access to services, in this unplanned type of networks. This paper proposes a QoE for CWN with no centralized entities, which is based on the IEEE 802.11e amendment to the IEEE 802.11 Standard, and employs a game theory approach. The proposed scheme permits the distribution of the load between different Access Points. It also provides to the users a mechanism for the selection of the best Access Point in order to satisfy their requirements, and to guarantee the equilibrium in the network.}, url = {fileadmin/papers/2010/2010-lora-QoE-Cooperative.pdf}, misc2 = {Online}, editor = {Gunnar Stevens, Volkmar Pipek and Markus Rohde}, publisher = {IISI - International Institute for Socio-Informatics}, address = {Bonn, Germany}, booktitle = {Workshop Proceedings of 9th International Conference on the Design of Cooperative Systems, International reports on socio-informatics, Aix - en - Provence, France}, event_place = {Aix-en-Provence, France}, event_name = {Mobile Collaboration Systems: Challenges for design, work practice, infrastructure, and business}, event_date = {May 2010}, language = {en}, ISSN = {1861-4280}, reviewed = {1}, author = {Lora Gir{\'o}n, M{\'o}nica Alejandra} }
