From: A novel dynamic reputation-based source routing protocol for mobile ad hoc networks

r n Node reputation for node n
R p Path reputation for path p
L p Packet loss probability for path p
\( \widehat{r_n} \) Sample of estimated reputation for node n
N p Number of intermediate nodes in path p
r k k-th sample of a node reputation
\( \overline{r} \) Mean value of rk
∆r k Deviation from the mean value of the sample rk
σ r Standard deviation of rk
c k Cumulative moving average (CMA) of the k samples of rk
\( \overline{c_k} \) Mean value of ck
∆c k Deviation from the mean value of ck
σ c Standard deviation of ck
w k Exponentially weighted moving average (EWMA) of the k samples of rk
β Weight for the next sample to be averaged in the EWMA
w 0 Initial value for the EWMA
\( \overline{w_k} \) Mean value of wk
∆w k Deviation from the mean value of wk
σ w Standard deviation of wk
f k First difference of the wk values
d k Second difference of the wk values
