“…The energy efficiency of MAC protocol in WSN is very sensitive to number of nodes competing for the access channel. It will be very difficult for a MAC protocol to accurately estimate the different parameters like collision probability, transmission probability, and so forth, by detecting channel [17], [18]. The repeated game is defined as G = {N, p, E}, where N is the set of players, which may be group of non-cluster head nodes or individual node in WSNs.…”
