Executive Summary

Self-powered wireless mesh networks have gained popularity as a cheap alternative for providing Internet access in many rural areas of the developed and, especially, the developing world. The quality of service that these networks deliver is often bounded by such rudimentary issues as the unavailability of electrical energy. Dependence on renewable energy sources and variable power consumption make it difficult to predict the available energy and provide guarantees on communication performance. To facilitate energy trend estimation the authors develop an energy flow model that accounts for communication and energy harvesting equipment hardware specifications; high resolution, time-varying weather information; and the complex interaction among them.
