  2. Outline • Introduction • TC for Energy • TC for Interference • ATASP Topology • Simulation • Conclusion

  3. Introduction • Topology Control • Energy-efficient • Low-interference Multi-Hop Ad Hoc Networks

  4. TC for Energy tmin + r tmin + r tmax + r Cisco Aironet 4800 card, r = 0.958tmin and tmax = 1.358tmin The minimum-energy path between two nodes always corresponded to a minimum-hop path.

  5. TC for Interference 1. Purely Geometric 2. Multi-hop communications

  6. TC for Interference

  7. TC for Interference

  8. TC for Interference

  10. ATASP Topology • All-To-All-Shortest-Path • ATASP has optimal PIC spanning factor • ρ(ATASP) = 1 • ATASP is connected iff G is connected • The communication graph G is composed ofΘ(n2) edges, and its ATASP subgraph is composed ofΘ(n2) edges as well

  11. ATASP Topology 0 1 2 3 6 4 5

  12. Simulation • 10~500 nodes • Distributed uniformly at random in the unit square • Two radio channel models: the quiteidealistic free space propagation model, and the log-normal shadowing model.

  13. Free Space Propagation

  14. Log-normal shadowing

  15. Free Space Propagation- different localized topologies

  16. Log-normal shadowing -different localized topologies

  17. Conclusion • In this paper given some model for topology control • Energy • Multi-hop Interference • Open question about the topology control • Interference • Energy • Delay • Throughput
