Mobile Information Collectors' Trajectory Data Warehouse Design

Trajectory Tracking of Two-Wheeled Mobile Robots, Using LQR Optimal Control Method, Based On Computational Model of KHEPERA IV

This paper presents a model-based control design for trajectory tracking of two-wheeled mobile robots based on Linear Quadratic Regulator (LQR) optimal control. The model proposed in this article has been implemented on a computational model which is obtained from kinematic and dynamic relations of KHEPERA IV. The purpose of control is to track a predefined reference trajectory with the best po...

Relay Node Placement and Trajectory Computation of Mobile Data Collectors in Wireless Sensor Networks

Data Gathering from Path Constrained Mobile Sensors Using Data MULE

In Wireless Sensor Network (WSN) sensor nodes are deployed to sense useful data from environment. Sensors are energy-constrained devices. To prolong the sensor network lifetime, now a days mobile robots (sometimes refer as data sink, data mules, or data collectors) are used for collecting the sensed data from the sensors. In this environment sensor nodes directly transfer their sensed data to t...

Extending UML for trajectory data warehouses conceptual modelling

The new positioning and information capture technologies are able to treat data related to moving objects taking place in targeted phenomena. This gave birth to a new data source type called trajectory data (TD) which handle information related to moving objects. Trajectory Data must be integrated in a new data warehouse type called trajectory data warehouse (TDW) that is essential to model and...

Trajectory data warehouse modeling based on a Trajectory UML profile: Medical example

Trajectory data is a new concept appeared with the continuous mobility imposed by social and professional daily life activities and the advance of mobile devices used to accomplish missions while moving. Trajectories data can be used either for transactional and analysis purposes in various domains (heath care, commerce, environment, etc.). For this reason, modeling trajectory data at the conce...
