Assume that a device can execute 3 million instructions for the same amount of energy (3J) used to transmit or receive 1 Kbit of data 100m by radio. The device has the option of sending a 100KByte binary program to a compute server 100m away, which when run will execute 60 billion instructions and exchange 10000 1Kbit messages with the device. If energy is the only consideration, should the device offload the computation or execute it itself? Assume computation on the device is negligible in the offloaded case.
