CT-Mapper: Mapping sparse multimodal cellular trajectories using a multilayer transportation network

Fereshteh Asgari, Alexis Sultan, Haoyi Xiong, Vincent Gauthier, more

Computer Communications > 2016 > 95 > C > 69-81

Mobile phone data have recently become an attractive source of information about mobility behavior. Since cell phone data can be captured in a passive way for a large user population, they can be harnessed to collect well-sampled mobility information. In this paper, we propose CT-Mapper, an unsupervised algorithm that enables the mapping of mobile phone traces over a multimodal transport network....

Nicolas Gensollen, Vincent Gauthier, Michel Marot, Monique Becker

2016 IEEE International Conference on Smart Grid Communications (SmartGridComm) > 180 - 185

2016 IEEE International Conference on Smart Grid Communications (SmartGridComm)

We propose here a control based method for improving the storage placement in a prosumer network where generators and loads are stochastic. The particularity of our approach is to use the energy required for stabilizing the system as a criterion for the optimization of the storage placement. We use a linearized AC model for the dynamic of the system and we consider the control inputs as being the...

2016 IEEE 17th International Symposium on "A World of Wireless, Mobile and Multimedia Networks" (WoWMoM)

Smartphones and other mobile devices are today pervasive across the globe. As an interesting side effect of the surge in mobile communications, mobile network operators can now easily collect a wealth of high-resolution data on the habits of large user populations. The information extracted from mobile network traffic data is very relevant in the context of population mapping: it provides a tool for...

Cross Layer Simulation: Application to Performance Modelling of Networks Composed of MANETs and Satellites

Riadh Dhaou, Vincent Gauthier, M. Issoufou Tiado, Monique Becker, more

Lecture Notes in Computer Science > Network Performance Engineering > Simulation Techniques > 477-508

The Cross layer concept is a new way to see the quality of service in the network. It consists in adapting the current mechanisms at one level to the underlying levels and the definition of information to share between, not necessarily adjacent, levels and the global optimisation instead of multiple optimisations. Performance optimisation of the whole system is a crucial step in the process of design...

Cross-Layer Simulation and Optimization for Mobile Ad-Hoc Networks

André-Luc Beylot, Riadh Dhaou, Vincent Gauthier, Monique Becker

IFIP — The International Federation for Information Processing > Mobile and Wireless Communication Networks > 13-22

This paper introduces cross-layer implementation with a multi-rate aware routing scheme and shows that SNR is an important information to use in a routing protocol. The existing routing protocol attempts to minimize the number of hops between source-destination pairs. We use a new metric definition to route the packets and to select the best available link along the path in a multi-rate protocol senario...

Network planning tool based on network classification and load prediction

Seif Eddine Hammami, Hossam Afifi, Michel Marot, Vincent Gauthier

2016 IEEE Wireless Communications and Networking Conference > 1 - 6

2016 IEEE Wireless Communications and Networking Conference (WCNC)

Real Call Detail Records (CDR) are analyzed and classified based on Support Vector Machine (SVM) algorithm. The daily classification results in three traffic classes. We use two different algorithms, K-means and SVM to check the classification efficiency. A second support vector regression (SVR) based algorithm is built to make an online prediction of traffic load using the history of CDRs. Then,...

2015 International Wireless Communications and Mobile Computing Conference (IWCMC) > 886 - 891

2015 International Wireless Communications and Mobile Computing Conference (IWCMC)

For several years, works on cognitive radio have been published allowing to reuse TV Whitespaces. On another hand, many new results appear on user and crowd mobility due to big data recent developments, especially from cellular traces. We propose here a method for cellular resource planning taking into account user mobility. Since users move, the bandwidth resource should also move accordingly. We...

Coalition formation algorithm of prosumers in a smart grid environment

Nicolas Gensollen, Monique Becker, Vincent Gauthier, Michel Marot

2015 IEEE International Conference on Communications (ICC) > 5896 - 5902

ICC 2015 - 2015 IEEE International Conference on Communications

In a smart grid environment, we study the coalition formation of prosumers that aim at entering the energy market. It is paramount for the grid operation that the energy producers are able to sustain the grid demand in terms of stability and a minimum production requirement. We design an algorithm that seeks to form coalitions that will meet both of these requirements: a minimum energy level for the...

In a network of devices in close proximity such as Device to Device (D2D) communication network, we study the dissemination of public safety information at country scale. In order to provide a realistic model for the information dissemination, we extract a spatial distribution of the population of Ivory Coast from census data and determine migration pattern from the Call Detail Records (CDR) obtained...

2015 IEEE International Conference on Pervasive Computing and Communications (PerCom) > 55 - 62

2015 IEEE International Conference on Pervasive Computing and Communications (PerCom)

This paper proposes a novel task allocation framework, CrowdTasker, for mobile crowdsensing. CrowdTasker operates on top of energy-efficient Piggyback Crowdsensing (PCS) task model, and aims to maximize the coverage quality of the sensing task while satisfying the incentive budget constraint. In order to achieve this goal, CrowdTasker first predicts the call and mobility of mobile users based on their...

NextCell: Predicting Location Using Social Interplay from Cell Phone Traces

Daqiang Zhang, Daqing Zhang, Haoyi Xiong, Laurence T. Yang, more

IEEE Transactions on Computers > 2015 > 64 > 2 > 452 - 463

Location prediction based on cellular network traces has recently spurred lots of attention. However, predicting user mobility remains a very challenging task due to the fuzziness of human mobility patterns. Our preliminary study included in this paper shows that there is a strong correlation between the calling patterns and co-cell patterns of users (i.e., co-occurrence in the same cell tower at...

2014 IEEE International Conference on Communications (ICC) > 124 - 129

ICC 2014 - 2014 IEEE International Conference on Communications

We study the problem of information dissemination in vehicular networks in this paper. Crucial information, such as traffic jamming status, is usually broadcasted inside the network. Each vehicle in the network has its own choice to either forward or drop packets for others. Although the energy consumption in general is not an issue in vehicular networks, forwarding every received packets is still...

Tracking topology dynamicity for link prediction in intermittently connected wireless networks

Mohamed-Haykel Zayani, Vincent Gauthier, Ines Slama, Djamal Zeghlache

2012 8th International Wireless Communications and Mobile Computing Conference (IWCMC) > 469 - 474

2012 8th International Wireless Communications and Mobile Computing Conference (IWCMC 2012)

Through several studies, it has been highlighted that mobility patterns in mobile networks are driven by human behaviors. This effect has been particularly observed in intermittently connected networks like DTN (Delay Tolerant Networks). Given that common social intentions generate similar human behavior, it is relevant to exploit this knowledge in the network protocols design, e.g. to identify the...

Improving link prediction in intermittently connected wireless networks by considering link and proximity stabilities

Mohamed-Haykel Zayani, Vincent Gauthier, Djamal Zeghlache

2012 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM) > 1 - 10

2012 IEEE Thirteenth International Symposium on "A World of Wireless, Mobile and Multimedia Networks" (WoWMoM)

Several works have outlined the fact that the mobility in intermittently connected wireless networks is strongly governed by human behaviors as they are basically human-centered. It has been shown that the users' moves can be correlated and that the social ties shared by the users highly impact their mobility patterns and hence the network structure. Tracking these correlations and measuring the strength...
