2. AUGMENTED PAPER Sensor Deployment and Target Localization Based on Virtual Forces Authors: Yi Zou & Krishnendu Chakrabarty Published in the Proceedings of the 22 nd Joint Conference of IEEE Computer and Communications Societies (INFOCOM 2003)

3. OBJECTIVES Goal of Work Efficiently deploying a mobile sensor network. Problems Addressed 1.Self Deployment 2.Coverage Maximization 3.Minimize Energy usage Technology Replaced Random deployment? Aim of Work Evaluate virtual force based sensor network deployment

4. PROPOSAL

6. CONTRIBUTIONS First time force based algorithm has been used to deploy sensors Energy reduction

7. CONTRIBUTIONS Paper #1Paper #2 First use of a force based algorithm to deploy sensors Energy use reduction compared to paper #1

8. IMPACT This paper has been cited just less than 1000 research papers. Uses an early version of the Player/Stage system in the paper from last week

9. EVALUATION Paper #1Paper #2 Emulation Mathematical Proofs Simulation Algorithmic Proof

10. OPEN PROBLEMS Paper #1Paper #2 Line of Sight Connectivity Mixing static nodes with dynamic nodes Node Collision Efficient Use nodes

11. DISCUSSION Ideas on combating the line of sight problem? How do you decide how many nodes to initially deploy?
