The mobility and ubiquity for any type of device to access the IPTV network must be supplied by the service provider. The minimum bandwidth required in the access network to provide IPTV services jointly with the necessity to guarantee the Quality of Experience (QoE) to the user makes the need of algorithms to combine different wireless standards and(More)
In this paper, we propose a secure spontaneous ad-hoc network, based on direct peer-to-peer interaction, to grant a quick, easy, and secure access to the users to surf the Web. The paper shows the description of our proposal, the procedure of the nodes involved in the system, the security algorithms implemented, and the designed messages. We have taken into(More)
We can find many cases where a spontaneous wireless ad-hoc network must be built for a limited period of time in a wireless mesh network: meetings, conferences, etc. One of the main aspects in a spontaneous network is to provide security mechanisms to the users. Confidentially, integrity, authentication, availability and no-repudiation should be provided(More)
One of the main problems when configuring ad-hoc networks is that with these networks don't have a central server with all the information of the network. If a new user wants to form part of a network must configure his device firstly. On the one hand, in this article we make an analysis of the different proposals for the configuration of ad-hoc networks(More)
—This paper presents a secure protocol for spontaneous wireless ad hoc networks which uses an hybrid symmetric/ asymmetric scheme and the trust between users in order to exchange the initial data and to exchange the secret keys that will be used to encrypt the data. Trust is based on the first visual contact between users. Our proposal is a complete(More)
