Outage probability analysis of HANs in multiuser downlink scenario for smart grid communications

Abstract

Due to the importance of reliable communications in smart grid, this paper evaluates the outage probability of HANs in multiuser downlink scenario. The probability density function (PDF) of the signal to interference and noise ratio (SINR) for each user in the HAN is derived from the amplitude distribution property of the classic indoor Saleh-Valenzuela (S-V) channel. The numerical results are obtained by Monte-Carlo simulation and are furthermore compared with those of ordinary multiuser downlink without interference cancelation and WiFi Direct techniques. The comparisons indicate the by applying these two techniques, the outage performance is greatly improve, namely, the reliability of downlink communications in HANs for smart grid is enhanced. © 2012 Springer Science+Business.
