Figure 14

Node’s power consumption profile for the high SI training scene. Note that the communication power consumption shown in this figure consists of transmission and reception power consumption. Part (a) of the figure shows the node’s power consumption profile using the CommonConfig algorithm. Using this technique, the encoding power consumption per each node are almost the same. Part (b) of the figure shows the node’s power consumption profile obtained using the MaximumFairness approach. Using this algorithm, the bitrate allocated per each node are roughly the same. However, nodes closer to the sink spend more energy for communication due to relaying other nodes’ data. It can be seen that node1 consume the highest energy as compare to the other nodes. On the other hand, (c) shows node’s power consumption profile obtained by the optimization-based technique that is not only more balanced but also has a smaller Pnet than the one obtained by the CommonConfig and MaximumFairness approaches.
