Algorithm 1

Rescaling l-DMEFxLMS algorithm for -nodes WASN.
(1) for all    do
(2)     % Copy local state of previous node (at node , )
(3)     % Obtain local coefficients to generate the output signal
(4)     % Provisional output signal
(5) for all    do
(6)     % Vector that contains reference signal filtered by estimated acoustic channels
(7) end for
(8)     % Update local state
(9) if      % If provisional output signal is greater than threshold
(10)     % Rescale provisional output signal
(11)     % Rescale its portion within its local state
(12)     % Updated local state with rescaled coefficients
(13) end if
(14)     % Generate output signal
(15) end for
(16)     % Updated global state of the network properly rescaled
(17) for all    do
(18)     % Disseminate global state of the network
(19) end for
