Time critical wireless data transmission in autonomous control applications

The following paper examines problems in fast wireless data acquisition and proposes solution. The paper examines the area of autonomously controlled vehicles. Necessity of well-timed data in such an application is vital, since moving vehicle could damage itself and surroundings. As an example of such a task, authors use recent FP7 project - STRATOS. Existing solutions do not fulfill node amount and frequency requirements of the application. Solution contains all components, transmission technology, media access algorithm and gateway design. The key element for reaching requirements is using parallel data transmissions, along with time division media access (TDMA) algorithm. Testing and simulation proved that designed wireless sensor network that is capable of delivering measurements from 140 sensors with a frequency of 300Hz.
