In addition, the transmission powers of allactive nodes are taken as 25 dBm, whereas for the sleep nodes it was setto 5 dBm.In Figure 8.26, the energy consumed for different routing protocols canbe observed. Because the Bellman Ford protocol consumes a radically higheramount of energy than other protocols, the graph is magnified to comparethe performance of OEDSR with the other protocols.
