For the network topology shown below, identify the optimal routes for source A to sink M according to the following criteria (describe how you compute the cost for the optimal route). The numbers X/Y along each link indicate the latency (X) and energy cost (Y) for transmitting a single packet over the link. The number Z under each node indicates the node's remaining energy capacity. a) Minimum number of hops. b) Minimum energy consumed per packet. c) Maximum average energy capacity (eliminate hops that would result in a higher. d) Maximum minimum energy capacity. e) Shortest latency
