This paper addresses the Internet of Things (IoT) paradigm, which is gaining substantial ground in modern wireless telecommunications. The IoT describes a vision where heterogeneous objects like computers, sensors, Radio-Frequency IDentification (RFID) tags or mobile phones are able to communicate and cooperate efficiently to achieve common goals thanks to(More)
Quality of Service (QoS) provi sioning in 3 generation cellular systems is one of the keys for the commercial success of these networks. Radio Resource Management (RRM) is the way to provide users with QoS. The main “building blocks” of the RRM layer are: Call Admission Control (CAC), packet classification, and packet scheduling. This paper focuses on the(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)
The fast-paced development of Unmanned Aerial Vehicles (UAVs) and their use in different domains, opens a new paradigm on their use in natural disaster management. In UAV-assisted disaster management applications, UAVs not only survey the affected area but also assist in establishing the communication network between the disaster survivors, rescue teams and(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)
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 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)
Wireless Mesh Network (WMN) is a promising wireless technology for several emerging and commercially interesting applications, e.g., broadband home networking, community and neighborhood networks, coordinated network management, intelligent transportation systems. It is gaining significant attention as a possible way for Internet service providers (ISPs)(More)
8 In this paper we investigate the potentiality and the benefits of a soft Vertical Handover (VHO) mechanism, 9 compared with the traditional hard approach. More specifically, we present an analytical scheme for seamless service 10 continuity in a heterogeneous network environment, modeled by means of a multi-dimension Markov chain. The call 11 blocking(More)
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)
