Battery lifetime is often an important performance metric when simulating networks containing wireless devices. When evaluating system or protocol performance, there are cases where it is useful for the battery model to more accurately reflect the complex electrochemical processes involved in battery discharge.
This paper describes an implementation of the KiBaM battery discharge model for INET. With regard to the INET implementation itself, the main technical issue is to extend the INET power model to more effectively handle both constant output voltage energy sources (mains power and simple battery models) and variable output voltage sources (complex battery models).
A custom battery testbed allows us to measure the discharge behavior of Li-coin cells under controlled conditions. The testbed is capable of coarse-grain modeling of the current draw associated with an IEEE 802.15.4 radio transmitting a frame. This enables a preliminary comparison between the simulation model and real discharge behavior.
