  2. Contents • Telecommunications • Wireless Sensor Network • Problem Formulation • Ant Colony Optimization • Computational Results • Conclusion and Future Work

  3. Telecommunications • Telephones • Television • Data transmissions • Internet • Security

  4. Wireless Sensor Network • Reconnaissance • Surveillance • Forest fire prevention • Volcano eruption study • Health data monitoring • Civil engineering

  5. WSN Layout Problem • High Energy Communication Node • Sensing Radius • Communication Radius • Fully Covered and Connected Area • Minimal Number of Sensors • Minimal energy

  6. Objective Function

  7. Real Ants Behavior

  8. Ant Colony Optimization Procedure ACO Begin initialize the pheromone while stopping criterion not satisfied do position each ant on a starting node repeat for each ant do chose next node end for until every ant has build a solution update the pheromone end while end

  9. Transition Probability

  10. Pheromone Updating

  11. Computational Example • Sensing area 500x500 • Coverage radius 30 • Communication radius 30

  12. Computational Results

  13. WSN Layout

  14. Conclusion and Future Work

  15. Thank for Your Attention
