Sensors positioning in outdoor environment with signal strength
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014Log-distance path loss model have been using as a simple positioning method because of its simplicity which is mainly depends on Received Signal Strength (RSS) along with path loss exponent and random Gaussian noise variable with zero-mean. This model can be extensively used in urban and remote area because it is related to energy representation.

Estimation of communication signal strength in robotic networks
2010 IEEE International Conference on Robotics and Automation, 2010In this paper we consider estimating the spatial variations of a wireless channel based on a small number of measurements in a robotic network. We use a multi-scale probabilistic model in order to characterize the channel and develop an estimator based on this model.

The Daylight Variation of Signal Strength
Journal of Applied Physics, 1937A rapidly moving recording galvanometer (Micromax) is used to maintain balance in a Wheatstone bridge. Received radio signals unbalance this bridge, so that an automatic record of voltage signal strength is taken. On daylight signals from nearby stations, the signals fluctuate rapidly during each day and night signals show a relationship dependent upon

Experimental characterization of DSRC signal strength drops
2009 12th International IEEE Conference on Intelligent Transportation Systems, 2009Dedicated Short Range Communication (DSRC) is gaining momentum as the protocol of choice for wireless vehicle safety applications by automotive original equipment manufacturers (OEMs) and road operators. DSRC is a low latency and reliable vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication protocol.

Absolute Localization via DSRC Signal Strength
2016 IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016Lane-level localization is the basis for successful deployment of Intelligent Transportation Systems. Global Navigation Satellite System can provide lane-level position in open (non-obstructed) environments. A new area of research aims for a collaborative approach to localization where one vehicle can leverage the localization information from other ...

GMTI tracking using signal strength information
2010 13th International Conference on Information Fusion, 2010Signal strength information is a standard output of a modern radar system. Provided the amplitude of the target returns exceeds the false alarm background, the consideration of signal strength may lead to improved target estimates, depending on the scenario. In this paper a Bayesian tracking algorithm is presented which incorporates the signal strength

Tracking with Biased Measurements of Signal Strength Sensors
2007 15th International Conference on Digital Signal Processing, 2007Sensors that measure received signal strength from moving targets may have bias that need to be accounted for if accurate tracking of targets in time is needed. When the bias is unknown, it has to be estimated together with the other unknowns of the system model. If the applied methodology for tracking is particle filtering and if the number of sensors

Signals of strength in crustaceans [PDF]
, 2012 Animals use signals for intra- and interspecific communication to deter predators, warn conspecifics of danger, attract mates and compete with rivals. The importance of signals for males competing for copulations with females has led to the evolution of extravagant ornaments and/or enlarged weapons in males of many species.

Received signal strength indication for movement detection
2015 Eighth International Conference on Mobile Computing and Ubiquitous Networking (ICMU), 2015Wireless networks are spreading continuously, filling our homes and the world around us. By using a ZigBee network we will show that a person can be detected by analyzing the fluctuations of signal strength inside the network. The simplicity of our approach means that it could be extended to all wireless networks.

Integrated Models and Their Usage in Predicting the Signal Strength
2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014There are many propagation models that address specific area and application's needs. Each model works well in specific application with specific data and algorithm. Mobile users are now expecting more and more ubiquitous user experience. It is critical to have an integrated model that provides a complete solution for deployment and optimization for ...
