A wireless sensor network (WSN) consists of distributed autonomous sensor nodes to cooperatively monitor/control physical or environmental conditions, such as temperature, sound, vibration. This page describes our activities in the area of WSN.

WSN Applications

Automotive E-safety System

  • responsible people:
  • short description:
    • wireless vehicle to vehicle communication, which should improve the active safety on the roads. The main goal is to prevent the mass car accidents with the distributed warning system. In consequences of an obstacle detection (driver's reactions - hard breaking, fast trajectory change...) the function unit starts to transmit a warning signal which is then distributed to other nearby vehicles and forwarded by them to cars a few kilometers ahead the obstacle.

Parkinson's disease monitoring

  • responsible people:
  • short description:
    • Wireless sensor motes placed on limbs (legs, arms) transmit periodically measured data to a central node for storing and evaluation. Once a day (or in predefined period) data from central node is downloaded to PC or PDA for analysis and computation of feedback in the form of brain stimulation or appropriate dose of medicine.

Real-Time Object Tracking with Wireless Sensor Networks

  • responsible people:
  • short description:
    • The aim of the thesis is to design and implement a wireless sensor network for object tracking under real-time constraints, using time division media access (TDMA).

ITEM - Implementation of Integrated TDMA and E-ASAP Module

  • responsible people:
  • short description:
    • The aim of the project is to design and implement TDMA communication protocol for wireless sensor networks, which integrates the TDMA and E-ASAP (Extended - Adaptive Slot Assignment Protocol).
