Wireless mesh networks are an appropriate solution for broadband home networks in order to establish a ubiquitous environment. One of the main challenges in ubiquitous networks is context-awareness and personalized service discovery. Many service discovery protocols have been proposed in the literature. The most significant is the Universal Plug and Play (UPnP) technology, based on the Simple Service Discovery Protocol (SSDP) and targeted for home network environment. However, the UPnP technology has some drawbacks and particularly does not consider user context. In this paper we present a framework that provides an extension for the UPnP architecture and employs context-aware concepts to achieve service discovery continuity in evolving environments where devices may move inside the home and change their point of attachment within the wireless mesh network. This extension is carefully designed for wireless mesh controllers, and is compatible with the existing UPnP framework. It keeps the process of service discovery as simple and automatic as possible.

International audienceInternet access everywhere has become a reality today, largely thanks to the deployment of numerous WiFi hotspots. However, controlling user access to the network remains a challenge because of the need for specific hardware and the lack of software standards. Using the OpenFlow protocol, we provide a new extensible way of designing and managing guest access architectures in the Cloud. We demonstrate the feasibility of such an architecture, with little impact on existing configurations when using virtual machines and Software Defined Networks. Our results can be used to build a real life testbed to test new mutualized guest access network architecture and improve hardware interoperability
