    Mobile Location-Driven Associative Search in DBpedia with Tag Clouds

    A primary contextual source for today's context-sensitive mobile phone apps is the user's location. The recent surge in the availability of open linked data can provide location-oriented semantic context, still wanting to be explored in innovative ways. In PediaCloud, the Android tool described here, the authors show how, they can...

    A Bandwidth Marketplace for Heterogeneous Mobile Networks

    In recent years, with the evolution of new and content-rich Internet services, mobile network operators face the challenging task to guarantee ubiquitous and seamless access to their customers, while minimizing the installation and operating costs of their network. On the other hand, in residential areas most of the network capacity...

    Efficient Bandwidth Allocation in Wireless Community Networks

    The network coverage and the number of residential users that a network operator may serve through a Wireless Mesh Network can be significantly increased by subleasing the available bandwidth to a subset of customers. In this paper, the authors propose an innovative mechanism to allocate the available bandwidth of a...

    A Nash Bargaining Solution for Cooperative Network Formation Games

    The Network formation problem has received increasing attention in recent years. Previous works have addressed this problem considering almost exclusively networks designed by selfish users, which can be consistently suboptimal. This paper addresses the network formation issue using cooperative game theory, which permits to study ways to enforce and sustain...

    Non-Cooperative Spectrum Access in Cognitive Radio Networks: A Game Theoretical Model

    Cognitive radio networks provide the capability to share the wireless channel with licensed (primary) users in an opportunistic manner. Primary users have a license to operate in a certain spectrum band; their access can only be controlled by the Primary Operator and is not affected by any other unlicensed (secondary)...

    Optimal Node Placement in Distributed Wireless Security Architectures

    Wireless Mesh Networks (WMNs) are currently accepted as a new communication paradigm for next-generation wireless networking. They consist of mesh routers and clients, where mesh routers are almost static and form the backbone of WMNs. Several architectures have been proposed to distribute the authentication and authorization functions in the WMN...

    Simplifying Enterprise Wide Authorization Management Through Distribution of Concerns and Responsibilities

    Authentication lets a system know who the users are, while authorization controls their resources access rights and what operations they are allow to perform. Resources have owners to whom the resources belong to. The owner knows best who is allowed to access her resources at any one time. Distribution of...

    Competitive Interference-Aware Spectrum Access in Cognitive Radio Networks

    Cognitive radio networks provide the capability to share the wireless channel with licensed (primary) users in an opportunistic manner. Primary users have a license to operate in a certain spectrum band; their access can only be controlled by the primary operator and is not affected by any other unlicensed (secondary)...

    Very Large-Scale Neighborhood Search Algorithms for the Design of Service Overlay Networks

    Service Overlay Networks (SONs) allow virtual operators to create and deploy value-added Internet services with Quality of Service guarantees, while leaving the underlying network infrastructure unchanged. The deployment of a SON can be very expensive, and hence its planning requires careful decisions, including the overlay nodes' placement and the capacity...

    Joint Spectrum Access and Pricing in Cognitive Radio Networks With Elastic Traffic

    This paper studies the economic interactions between secondary users and primary operators in a cognitive radio network scenario. Secondary users transmit their traffic, eventually splitting it over multiple available frequency spectra, each owned by an independent primary network operator. Users are charged a fixed price per unit of bandwidth used,...

    Joint QoS Routing and Dynamic Capacity Dimensioning With Elastic Traffic: A Game Theoretical Perspective

    Efficient dynamic resource provisioning algorithms are necessary to the development and automation of Quality of Service (QoS) networks. The main goal of these algorithms is to offer services that satisfy the QoS requirements of individual users while guaranteeing at the same time an efficient utilization of network resources. This paper...

    Socially-Aware Network Design Games

    In many scenarios network design is not enforced by a central authority, but arises from the interactions of several self-interested agents. This is the case of the Internet, where connectivity is due to Autonomous Systems' choices, but also of overlay networks, where each user client can decide the set of...

    Multi-Channel Power-Controlled Directional MAC for Wireless Mesh Networks

    Wireless Mesh Networks (WMNs) have emerged recently as a technology for providing high-speed last mile connectivity in next-generation wireless networks. Several MAC protocols that exploit multiple channels and directional antennas have been proposed in the literature to increase the performance of WMNs. However, while these techniques can improve the wireless...
