Presentation Transcript

  1. Implementation and Analysis of an Overhearing Cost Model based Broadcast Method for Wireless Sensor Networks Newton Alex Venkatraman Jayaraman

  2. Overview • What is a Wireless Sensor Network? • Broadcasting • Problem Statement • What is Overhearing Cost? • Experimental Setup • Methodology • Current Stage • References

  3. What is a Wireless Sensor Network? • Large number of sensor devices • Ad Hoc Network • complex sensor nodes with • communication, processing, storage capabilities

  4. Broadcasting • Packet transmitted to every node in the network • Wide range of applications • Updating Software • Teleconferencing • Online gaming

  5. Problem Statement • Implementing and analyzing an energy efficient broadcast method with focus on the Overhearing Cost model • Suggest improvements to the algorithm based on the analysis

  6. What is Over Hearing Cost? • Consumption of energy by a non-designated receiver is not negligible.

  7. Experiment Setup • Measurements • Transmission power • Receiving power • Circuit power • Overhearing power

  8. Methodology • Implement a spanning tree algorithm on the sensor network • Record the power measurements assuming zero overhearing cost • Build the spanning tree with this cost • Record the power measurements considering the overhearing cost • Rebuild the spanning tree with this new cost • Verify if the spanning tree changes with this new set of measurements • Simulate the nesC code in TOSSIM • Implement on Mica2 motes

  9. Cumulative Designated Receiver Power Algorithm

  10. Current State and Things to be done • Coding of distributed spanning tree creation algorithm is almost complete • Has to be tested on Tossim and eventually on the motes • Power measurement
