Energy Efficiency-Spectral Efficiency Trade-off in Interference-Limited Wireless Networks with Shadowing
Résumé
This presentation deals with the energy-efficiency spectral-efficiency (EE-SE) tradeoff in regular hexagonal interference-limited networks. We aim to characterize the EE-SE region when non negligible static circuitry power consumption is assumed and when several frequency reuse factors as well as shadowing are taken into account. Our contribution is three-fold: i) a parametric expression of the interference to signal ratio, a.k.a. f-parameter, obtained with a curve fitting approach is proposed, ii) the epsilon-EE-SE tradeoff is then studied when several frequency reuse factors are considered and iii) a new characterization, called the EE-SE tradeoff, is proposed when shadowing is considered. This definition relies on the outage capacity achievable and its corresponding EE and remains particularly useful when long-term fading is present.
