A reliable, accurate, and affordable positioning service is highly required in wireless networks. In this paper, the novel Message Passing Hybrid Localization (MPHL) algorithm is proposed to solve the problem of cooperative distributed localization using distance and direction estimates. This hybrid approach combines two sensing modalities to reduce the uncertainty in localizing the network nod...

Rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. Among different techniques, RSS-based  schemes and in particular oneof its variants which is based on Graph-based Semi-Supervised Learning (G-SSL) are widely-used approaches The superiority of this scheme is that it has low setup/training cost and at the same ti...

Workpiece localization has direct relations with many manufacturing automation applications. In order to gain accurate workpiece measurement by coordinate measuring machines (CMM) or on-machine measurement system, the touch trigger probe is widely adopted. In spite of the high repeatability of the touch trigger probe, there are still error sources associated with the probe. In this paper, we wi...

erosion and sediment movement phenomena are one of the most complex issues in management of rivers drainage areas that in water projects are very important. that its measurement wants high time and cost. issue of surface runoff in river basin is a complex issue that human knowledge and understanding about its physical laws a viewpoint of some mathematical formulas is limited. in this study to i...

We present a new error localization tool, Archie, that accepts a specification of key data structure consistency constraints, then generates an algorithm that checks if the data structures satisfy the constraints. We also present a set of specification analyses and optimizations that (for our benchmark software system) significantly improve the performance of the generated checking algorithm, e...

Determination of mobile localization with time of arrival (TOA) signal is a requirement in cellular mobile communication. In some of the previous methods, localization with non-line-of-sight (NLOS) paths can lead to large position error. Also for simplicity, in most simulations suppose non stationary actual environments as stationary. This paper proposes (residual test + recursive least square)...

A method for the joint localization and orientation estimation of a directional sound source using distributed microphones is presented. By modeling the signal attenuation due to the microphone directivity, the source directivity, and the source-microphone distance, a multi-dimensional search over all possible sound source locations and orientations is performed. This sound source scene reconst...

This paper presents an algorithm of simultaneous localization and mapping (SLAM) with a scanning laser range finder and radiofrequency identification technology (RFID) to include landmarks of an object or place within a generated map. For the testing phase was used of simulation software Anykode’s Marilou and was used to build a virtual mobile robot with the features of the Pionner 3-AT, includ...

− In sensor networks, randomly distributed sensor nodes have to determine its own positions to assign measurements to locations. Due to limited resources of the nodes, resourceaware positioning algorithms are required. In this paper, we present a solution to minimize the positioning error of the “Weighted Centroid Localization” algorithm (WCL) using hop count determination. Compared to other ap...
