A method is intended for computing online channel loss rate and collision loss rate of at least one communication link established between nodes (N1, N2) of a network (WN) using a random access MAC protocol. This method comprises the steps of i) dividing time in probing windows and transmitting a chosen number S of probe packets during each probing window from a transmitter node (N1) to a receiver node (N2) linked therebetween, ii) measuring a packet loss rate from probe packets lost on this communication link during a probing window, iii) scanning each probing window with smaller sliding windows, each having a size Wk smaller than S, to identify the sliding window during which only channel losses occur, and then for computing a channel loss rate on this communication link from this identified sliding window, and iv) computing a collision loss rate on this communication link by subtracting the computed channel loss rate from the measured packet loss rate.
Method for computing online channel loss rate (pch) and collision loss rate (pcoll) of at least one communication link established between nodes (Nj) of a network (WN) using a random access MAC protocol, characterized in that it comprises the steps of:
