Energy consumption on one bit of transmitted data depends on line budget. But I think for your purpose default values of wifi transmitters will be enough (see link below).

No one usually simulates energy consumption from node movements. It has no relation to data transmission. Consider only energy consumption from transmission.

Simplifying, the communication energy consumption greatly depends on the:

- Technology (e.g., transmission mechanisms and power saving features)

- Data pattern (how the data is sent)

- Radio environment (e.g., signal strength or other users)

There is a substantial difference between technologies (e.g., WiFi vs. cellular), and the impact of the different aspects such as the data pattern on the energy consumption. For example, intermittent transmissions are very wasteful in cellular networks, but the impact is much lower in WiFi.

As Valeriy said, there is no clear correlation between the movement and the energy consumption. However, the movement can impact the received signal strength and thus the energy consumption.

I add a link to a paper that explains the energy consumption of 3G and WiFi focusing on the data pattern. The second one focuses on the signal strength in the cellular context.
