	abstract = {For sure, Wireless Sensor Networks (WSNs) are becoming an ultimate part of next generation mobile networks. They are a master piece for Ubiquitous computing. Indeed, they sustain development of numerous paradigms/ technologies such as distributed ambient intelligence, context-awareness and future mobile networking (e.g., B4G and 5G). Battery life remains one of the crucial problems to handle. In this article we propose an infrastructure-based topology using mobile ferries (mobile micro-base stations). In real life, a ferry could be robot, bus, tram, train or any other engine scrutinizing periodically a given area. Yet, message ferries are moving along concentric annulus and may collect data generated by the static sensors (could be classic sensors, smart meters, wearable devices, etc.) randomly distributed on given area. Next, transmissions are performed in a ferry-to-ferry forwarding scheme till arriving at the sink. Considered ferries could sense themselves data and therefore behave as mobile sensors allowing better awareness on the area state [1-3]. Our scheme could also assist Machine-to-Machine communications to increase the network lifetime, with potentially some cognitive-radio capabilities and opportunistic detection and access. Our proposal can easily be integrated in a smart-city for better interaction and green communications. Next, we present a queueing model (queues with finite capacity) to handle the generated traffic and to analyze the behavior of mobile ferries. We provided a close-form expression for both end-to-end throughput and end-to-end delay. The main objective of this work is to improve the energy efficiency of the cognitive sensors by asking cognitive sensors to not care about forwarding data of each other except for urgent data, this latter point is out of the scope of the paper. These static sensors will only care about data sensing, which will reduce their individual energy consumption. {\textcopyright} 2015 Elsevier B.V.},

	abstract = {We study energy conservation and system performance of decentralized cognitive radio network with cognitive users. Every cognitive radio (CR) user needs to sense the channel to send data, if the channel is unoccupied by a licensed user only one winner transmits its data. Hence, all other users waste their energy in sensing the licensed bands and in negotiating the resource access without managing to transmit data packets. We formulate the sensing-energy tradeoff problem for distributed cognitive radio network as a coalition formation game. Our contribution is to apply the coalitional game design to the most important phases of cognitive radio network (CRN): sensing and data transmission. The concept of coalitional game may enforce the cooperative behavior of CR users in order to improve the system performance (energy and delay.). The network is modeled using a coalitional game in partition form with non transferable utility (NTU). After forming coalitions, no CR user in those coalitions aim to change its position. Indeed, the members of this coalition will cooperate both in sensing and access phases to improve system performance. The selfish behavior becomes evident when the cognitive users are constrained to send their data in a short delay and with a minimum of energy consumption. Our proposed algorithm explains how the selfish atittude of the cognitive user leds to join the coalition that increases its individual gain, and tacitly to improve the performance of the entire system. {\textcopyright} 2014 IEEE.},

	abstract = {Vehicular Ad Hoc Network (VANET) is considered as a special application of Mobile Ad Hoc Networks in road traffic, which can autonomously organize networks without infrastructure. VANETs enable vehicles on the road to communicate with each other and with road infrastructure using wireless capabilities. In the last few years, extensive research provided several routing algorithms to extend Internet connectivity to VANETs through fixed gateways installed along the road. However, most of these algorithms have not been effective because of the high mobility of vehicles in the road. In this paper, we propose a routing algorithm which based both on the congestion game to resolve the problem of network congestion and on mobile gateways to resolve the problem of high mobility in VANET. Therefore, the proposed algorithm is a prediction done by each node in the network that helps them to reach the optimal route to access Internet. Simulation results validate the algorithm and show its robustness under two scenarios. In the first one, we examine the algorithm with fixed gateways installed along the road to validate the connectivity to the Internet. Whilst in the second scenario, we examine the algorithm with mobile gateways to show the effectiveness of gateways{\textquoteright} mobility on the capacity of communication and the Internet access in VANETs. {\textcopyright} 2014 Praise Worthy Prize S.r.l. - All rights reserved.},

	abstract = {To ensure connectivity in highly sparse Wireless Sensor Networks (WSNs), we consider a Ferry-assisted Wireless Sensor Network (FWSN). In our FWSN, message ferries moving along concentric annulus collect the static sensors generated packets and propagate them throughout a ferry-to-ferry forwarding schema to the sink. Moreover, a ferry may embed a sensor and then could be assimilated to a mobile sensor node generating its own data. We provide a mathematical framework based on queuing theory to model the network and analyze its performances in terms of end-to-end throughput. Some of our findings are the characterization of the forwarding queues{\textquoteright} stability and the average end-to-end throughput as well. At stability, we notice a special feature where the average end-to-end throughput becomes independent of the choice of the weighted fair queuing. {\textcopyright} 2013 IEEE.},

	abstract = {The Wireless Body Sensor Network (WBSN) is a wireless network used for communication among sensor nodes operating on or inside the human body in order to monitor vital body parameters and movements. The design and the development of such systems for health monitoring have gained a lot of attention recently in both the research and the industry. Mainly motivated by the increasing of healthcare costs and propelled by the recent advances in the development of miniature health monitoring devices. This paper presents a preventive health care system with a flexible design. By using sensors nodes in combination with a mobile data collector, both daily continuous monitoring as well as specific controls are provided. In this work, we propose a system based on an architecture with heterogeneous nodes to provide continuous monitoring. A model has been defined to describe the system global behavior. An important aspect of this work is that we propose a model driven (MDE) approach to derive the behavior of each node in the network from the system global behavior. The derived behaviors include the synchronization messages to ensure the global coordination among the system components. {\textcopyright} 2013 IEEE.},
