Full textIn the aftermath of a natural or industrial disaster, locating individuals is crucial for first responders. However, disasters can cause extensive damage to the network infrastructures and a generalized loss of communication among survivors. In this thesis, we present a network support solution that provides a post-disaster geolocation-collecting service that relies on inter mobile device connections. On top of this dynamically built network, survivors' mobile device that get into contact exchange information about geolocation of others they have encountered and risk areas they have seen. Such information is routed towards pre-defined data collection centers, endowed with resilient processing and storage equipment, where first-responders can exploit it. Whe also present our mobility model, specific to crisis situations, that we used to conduct experiments on the ONE simulator. We evaluate the effect of different parameters of mobility and communication on our system performances. We especially analyse the impact of the proportion of motionless people. The feasability of our architecture has also been validated through the building of a physical test platform, based on pico-computers (Raspberry Pi). We finally contributed to define a new local centrality metric for time varying graphs, which could be used to infer useful information for routing

Full textIn the domain of Computing with words, fuzzy linguistic approaches are known to be relevant in many decision-making problems. Indeed, they allow us to model the human reasoning in replacing words, assessments, preferences, choices, wishes, etc. By ad hoc variables, such as fuzzy sets or more sophisticated variables. In this thesis, we present a new fuzzy representation model to deal with unbalanced linguistic term sets that allow us to handle data with precision and accuracy. This model is based on our fuzzy semantic 2-tuples that we introduce. We apply these semantic 2-tuples to perform a fuzzy semantic interpretation of words in a natural langage dialog context for a geolocation application

Full textThe context of the thesis is the transmitters geolocalization (position estimation in the space) of radiocommunication from several widely spaced multi-sensor stations. The conventional geolocalization methods as the tirnagulation are in 2 staps (the first step estimates intermediate parameters and the second step "merges" these mesures from the stations in order to obtain the transmitters positions). The 1 stap methods use the observertions from all the stations to directly and optimally estimate the sources positions. Directly handling the signals on the global array (composed of all the local stations) leads to a broadband effect on the signals between the stations.The thesis proposes to study the residual broadband effect on the global array of the 1 step methods. Then we propose improvements on some 1 step geolocalization methods, especially based on the random matrix theory in large dimension and on the introduction of a new method named LOST-FIND. Finally, a new approach differently tackling the braodband problem has been introduced and leads to TARGET algorithm

Full textNowadays, the localization of a device or person has become mandatory. If many solutions exist for outdoor environment, as the GPS one, any fails to provide an expected accuracy for indoor environment because of the multipath phenomena and the attenuation of signals crossing walls. This thesis focuses on the localization problem in buildings by using existed technologies in smartphones and tablets managed by Android OS - which is available in several brands. The indoor localization systems are using different technologies like radio-frequency (RF) waves or inertial sensors embedded in handsets. In the RF case, they use anchors or beacons, whose position impacts the localization performance for the covered zone. Our first contribution was the placement optimization of beacons using simulated annealing algorithm. Next to improve the localization performance, the inertial sensors, embedded in smartphones, have been used. The pedestrian dead reckoning (PDR) algorithm employs the extracted signals from the inertial sensors and determines the path done since a known position. These extracted signals are affected by the intrinsic parameters of sensors and they are corrupted by noises. The calibration of the sensors is compulsory to obtain data that could be used to estimate the walking orientation and the number of done steps by the user. It is often supposed that the walking orientation is the same as the smartphone orientation; however it might be interesting to consider the bias between these two orientations. A last contribution, in this thesis, consists on a proposed algorithm for step detection using fuzzy logic

Full textOriginality of the proposed work We propose a new indoor tracking method which can be used on mobile nodes. Our method uses only the received signal strengths as input information and does not require a cinematic motion model to track the mobile node. Indoor Tracking We discuss in detail the features of our approach and its resulting tracking algorithm. Indoor Tracking vs maximum likelihood based Tracking We compare our tracking method to other tracking techniques based on maximum likelihood tracking. Indoor Tracking using signal maps We built two signal maps on two different sites, each of which is equipped with 4 and 5 access points respectively. We evaluated the performances of our algorithm using these signal maps. Investigating WIFI Signal Statistical Properties We also analyzed the statistical properties of the 802. 11 signal strengths. Specifically, we investigated the time-dependent noise affecting the received signal strengths, the stationary aspect of the RSS statistics (mean received signal strength) when the observer remains motionless. Then we explored the time-independent noise which occurs during the building of signal maps. We also use a geostatistical approach to analyze, model and predict mean signal strengths Keywords : Signal maps, 802. 11, statistical filtering, geostatistics. Indoor tracking, indoor positioning
