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 |
