The RSSI is also modeled using clusters, and the probability
mass function (PMF) of the RSSI being in one of
the clusters is determined. This PMF is determined for
each of the clusters that represent arm positions. The results
show high correlation between the arm position and
RSSI. On average, the RSSI cluster can be determined
from the arm-position cluster with 81% certainty.
An algorithm is developed that predicts the next RSSI
cluster from the current arm-position cluster. The experimental
evaluation shows that RSSI predictions can be
made with an average error of 3:7 dB, which is 4:2% of
the average RSSI
