Abstract: In critical and life threatening situations faced by Soldiers on the battlefield, timely response to complex information is required. In such situations, battlefield computation can help to distill data into actionable information that can lead to better decision-making and outcomes. However, computing power is limited on the tactical edge due to size, weight, and power constraints of a Soldiers mobile device. One potential solution to this problem is to offload the computation to a more powerful computer to obtain an answer as fast as possible. However, this strategy comes at the cost of the introduction of a delay due to communication latency. It is therefore important to design the offloading mechanism intelligently. This report, presents a model to estimate the performance of offloading systems in current and future scenarios. The modularity of this model allows system designers to replace model components with the accuracy and level of detail necessary for their analyses. This report examines how this type of model is useful for making decisions about when and where to offload jobs, as well as making hardware acquisition decisions for improving the system over time.
