|Blough D., Leoncini M., Resta G., Santi P. k-NEIGHLEV: a Practical Realization of Neighborhood-Based Topology Control in Ad Hoc Networks. Technical report, 2003.|
|Neighborhood-based topology control has been proven to be very effective in reducing energy consumption and increasing network capacity in ad hoc networks. In this paper, we present a practical realization of this approach that does not rely on distance estimation. Instead, the protocols presented in this paper leverage a feature typical of current wireless cards, namely that discrete power levels can be used for transmission. Ours are the first discrete-power-level protocols that do not require changing the power level on a per-packet basis. We demonstrate, through simulation, that the excellent performance of neighborhood-based topology control is maintained in this more practical setting. We also show that significant energy savings can be obtained if the power levels are optimized for topology control, rather than chosen in an ad hoc manner. Finally, we extend our approach to provide a neighborhood-based topology control protocol that is suitable for mobile networks.|
