The framework assumes users are directly involved, or have direct interest, on their communication system. Therefore it can place user-related constrains on the behavior of the system. Groups of interest, formed either implicitly or explicitly by users, are considered inside the community concept, which the framework supports. For the realization of this concept it is required a new knowledge and logic layer, which we describe in this work. This framework has been instantiated and tested in a small environment, and provided social aware service access authorization. The results showed the added flexibility of our framework, and its ability to integrate diverse user requirements.</p> autonomic management community Network Policy Mon, 30 Jan 2012 11:53:04 +0000 jpbarraca 425 at https://atnog.av.it.pt User Centric Community Clouds https://atnog.av.it.pt/publications/user-centric-community-clouds <p>With the evolution in cloud technologies, users are becoming acquainted with seamless service provision. Nevertheless, clouds are not a user centric technology, and users become completely dependent on service providers. We propose a novel concept for clouds, where users self-organize to create their clouds. We present such an architecture for user-centric clouds, which relies on self-managed clouds based on doctrine and on identity management concepts.</p> cloud community identity Fri, 16 Sep 2011 15:57:15 +0000 jpbarraca 372 at https://atnog.av.it.pt An Architecture for Community Mesh Networking https://atnog.av.it.pt/publications/architecture-community-mesh-networking <p>The advances on wireless mesh networks are shifting the communications paradigm, where users can benefit from their cooperation to exchange information and make use of the spectrum space, forming wireless neighbourhood communities where resources are shared and services are distributed. This paper presents a modular cross-layer community management architecture, which considers that communities are formed and managed at different layers, from physical to application. It focus in more depth on one of its modules, implementing a community discovery mechanism designed to work in wireless mesh networks, and able to perform community advertisement and discovery with low overhead and delay, as compared to current approaches.</p> architecture community mesh Service Discovery Mon, 21 Jun 2010 15:07:55 +0000 jpbarraca 225 at https://atnog.av.it.pt Managing Community Aware Wireless Mesh Networks https://atnog.av.it.pt/publications/managing-community-aware-wireless-mesh-networks <p>Wireless mesh networks, due to their typical architecture and deployment, are able to respond to user expectations as no other technology allows. Its typical multi-level approach facilitates local interactions by nearby wireless nodes from multiple users. Also, adaptation to user expectations on a dynamic manner is able to of further enhancing the capacity of these networks, while increasing its ubiquity. Nevertheless, these networks have no management model. In the paper we present the foundations for a management model for community aware networking. Design challenges for community management are identified and a management framework supporting the relevant concepts, linking social aspects and technology, is described.</p> community management mesh Wireless Mon, 21 Jun 2010 15:04:48 +0000 jpbarraca 224 at https://atnog.av.it.pt Ontology driven Framework for Community Networking Management https://atnog.av.it.pt/publications/ontology-driven-framework-community-networking-management <p>Wireless technologies present many benefits when used to deploy metropolitan networks. Resilience, cost, adaptability and self-organization are some of the benefits provided by Wireless Networks. Especially when mesh technologies are used, wireless networks are adequate for the deployment of (user-centric) community networks. The increased participation of users and the social relations existing among them makes desirable the merging of the mesh and social aspect of these networks. If proper interfaces are deployed, users are able to map existing (or to be developed) social structures such as communities into the mesh network. This paper focuses on the problem of creating a community driven mesh network, and in the representation and maintenance of user relations, trust and functional parameters. We present a novel ontology designed for the management of such environments.</p> community framework management Network ontology Mon, 21 Jun 2010 14:50:01 +0000 jpbarraca 222 at https://atnog.av.it.pt Role Based Cross-Layer Communities in WMN https://atnog.av.it.pt/publications/role-based-cross-layer-communities-wmn <p>The community notion can be exploited as a rational concept leading users to cooperate in sharing resources on Wireless Mesh Networks. We propose a novel concept for self-organizing networks, where multiple entities (network elements or users) collaborate to achieve common goals, and in particular, to establish the basic connectivity and service delivery infrastructures. The resulting architecture is based on wireless mesh communications, with different entities taking different roles in the communities in a cross-layer approach. These communities can collaborate, leading to increasingly complex and geographically extended scenarios.</p> community mesh Network RBAC Wireless Mon, 21 Jun 2010 14:47:41 +0000 jpbarraca 221 at https://atnog.av.it.pt Community Building over Neighborhood Wireless Mesh Networks https://atnog.av.it.pt/publications/community-building-over-neighborhood-wireless-mesh-networks <p>The fourth generation (4G) network paradigm has long been sought. A user-centric vision for such “always best connected” next-generation 4G networks is neighborhood Wireless Mesh Networks (WMNs). The vision for WMNs reflects the trade- off between the immediate self- interest of the user, and the user’s need for social contacts: Users would pool their resources in order to support the creation and operation of the underlying communication network (participating at all physical, access, and network layers), but also for service provision on top of it. We argue that the design of communities suitable for this environment will encourage users to participate, enable trustworthy network creation, and provide a social layer, which can be exploited in order to design cross-layer incentive mechanisms that will further encourage users to share their resources and cooperate at lower layers.</p> community mesh neighborhood Wireless Wed, 28 Oct 2009 14:15:28 +0000 jpbarraca 162 at https://atnog.av.it.pt
