A NS-3 module for LTE UE energy consumption
NS-3 has evolved into a very popular simulator platform for networking research studies. As energy consumed by LTE user equipment (UE) is of keen interest to researchers working in wireless networks, they often analyze the energy consumed by a UE when running network simulations. Thus, there is a stringent need for the underlying simulator to have an energy consumption model, but NS-3 currently does not have a LTE UE energy expenditure module. In literature, the LTE UE energy expenditure is profiled and modeled for a commercial UE. A corresponding implementation of the same is needed in NS-3. In this paper, we present the design and implementation details of LTE UE energy model in NS-3 and then validate it by running various experiments. Our implementation of LTE UE energy consumption model yields the expected power profile in our experiments with varying scheduling of resources to UEs. We made the LTE UE energy module code open [2] for the research community to get benefited.
