Table 1 Localization error (LE) of PDQ with R i = 3 due to variations of the model parameters

From: Probabilistic distance-based quantizer design for distributed estimation

Decay factor α 1.8 1.9 2 2.1 2.2
LE (PDQ) 1.5484 0.9270 0.7038 0.9535 1.5936
Gain factor g i 0.8 0.9 1 1.1 1.2
LE (PDQ) 1.2213 0.8614 0.7017 0.7841 0.9928
  1. LE = \(\frac {1}{100}\sum _{l~=~1}^{100} E_{l}(\parallel x-\hat {x}\parallel ^{2})\), where E l is the average localization error for the lth five-sensor configuration and is expressed in meter
