An example illustrates the idea of the PSRA protocol, where the range of the observation x is divided in to one censored region (\({\mathcal {C}}_1\)) and four uncensored regions (\({\mathcal {U}}_1\), \({\mathcal {U}}_2\), \({\mathcal {U}}_3\), \({\mathcal {U}}_4\)). The collection time (T) is equal to 16 and divided into \(M=4\) and \(K=4\). Assume that there are \(n_m\) sensor nodes with \(x \in {\mathcal {U}}_m\), for \(m=1, 2, 3, 4\). They will send their data bits at a time slot in the mth frame with a probability \(\frac{\rho _m}{K}\). As a result, idle time slots (I), successful time slots (S), and collision time slots (C) will happen
