(d) Layout of a 150-node r<strong>and</strong>omnetwork.plot as shown in Figure 8.27, it can be seen that OEDSR protocol performsbetter than AODV <strong>and</strong> DSR. This is because OEDSR uses an optimal routeto the BS by selecting nodes based on the available energy over averageE2E delay times distance metric. Moreover the distance metric will ensurethat the numbers of RNs are minimized. In consequence, the energy usedto transmit packets is minimized in case of the proposed scheme as only afew of the nodes are selected to transmit the data to the BS.
