This paper addresses mobility control routing in wireless networks. Given a data flow request between a source-destination pair, the problem is to move nodes towards the best placement, such that the performance of the network is improved. Our purpose is to find the best nodes selection depending on the minimization of the maximum distance that nodes have(More)
Aerial robotics can be very useful to perform complex tasks in a distributed and cooperative fashion, such as localization of targets and search of point of interests (PoIs). In this work, we propose a distributed system of autonomous Unmanned Aerial Vehicles (UAVs), able to self-coordinate and cooperate in order to ensure both spatial and temporal coverage(More)
— In this work we investigate the deployment of wireless nodes in order to maximize the lifetime of a data flow. We develop a mathematical model for determining the best placement of nodes by taking into consideration the energy of each node involved in the data flow. By using our mathematical model we achieve two major objectives: the maximization of the(More)
In this paper we want to explore a new approach for security mechanisms design and deployment in the context of Internet of Things (IoT). We claim that the usual approach to security issues, typical of more classical systems and networks, does not grab all the aspects related to this new paradigm of communication, sharing and actuation. In fact, the IoT(More)
In the context of hierarchical mobile IPv6 integrated with a fast handover mechanism, this paper proposes two mobility anchor point (MAP) selection algorithms, both based on the classification of users depending on their mobility. Furthermore, an enhancement of one of the two algorithms is presented; it introduces the concept of bufferization at MAP level.(More)
Recently, wireless self-organizing networks are attracting a lot of interest in the research community. Moreover, in the last decade many mobile devices have appeared in the market. Exploiting mobility in a wireless environment, instead of considering it as a kind of disturbance, is a fundamental concept that the research community is beginning to(More)
In this work, the optimal sensor displacement problem in wireless sensor networks is addressed. It is assumed that a network, consisting of independent, collaborative and mobile nodes, is available. Starting from an initial configuration , the aim is to define a specific sensors displacement, which allows the network to achieve high performance, in terms of(More)
The present work is focused on <i>Software Defined Radar - (SDR)</i> paradigm, which gives a more versatile solution when compared to classical radar systems. Thanks to this new system model, most of the fundamental operations, such as signal generation, filtering, up and down conversion, are easily implemented via software. The objective of this paper is(More)
There are many critical issues arising in Wireless Sensor and Robot Networks (WSRN). Based on the specific application , different objectives can be taken into account such as energy consumption, throughput, delay, coverage, etc. Also many schemes have been proposed in order to optimize a specific Quality of Service (QoS) parameter. With the focus on the(More)
