On the Impact of Energy Dissipation Model on Characteristic Distance in   Wireless Networks
  In this paper we investigate the dependency of characteristic distance on energy dissipation model. Both the many-to-one and any-to-any communication paradigm have been presented for performance analysis. Characteristic distance has been derived for three different cases. This study will be useful for designing an energy-efficient wireless network where nodes are energy-constrained.
