My concern is about Energy Efficiency Model for WBANs. In a wide sense, I'm looking for ways to model the whole network in terms of power and energy.

How much average power is required to keep an IoT sensor and its aggregate communication devices operational for long periods (energized throughout its life cycle inside a network)?

What is the energy level to maintain an autonomous system for years of operation in a near-body power harvesting context for WBANs?
