Abstract

The prediction of resource consumption is an essential task in the development of heavily resource-constrained systems, like smartphones and wireless sensor networks. In particular, good estimations on energy consumption are difficult to achieve, as they depend on the application's behavior, the used hardware and environment parameters. To address these issues, we introduce MobiSIM, an open-source OMNeT++ simulation library. MobiSIM allows the modeling of embedded systems to gain valuable information on the system's dynamic characteristics of resource consumption. The benefit of MobiSIM over other simulation systems is the focus on resource usage. Most other simulators focus on highly detailed system models to allow for the execution of native program code. These simulators are highly platform specific and complex to handle. We decided to use a coarse-grained, event-driven and platform-independent system model while still using detailed resource models for various devices. We will show that for several simulation purposes the application code can be modeled by a behavioral description, rendering instruction-accurate code execution unnecessary.
