Interference power recycling in two-scale ad hoc wireless networks

A two-scale ad hoc wireless network is envisaged in which the interference power generated in long-range connections is recycled by the surrounding wireless nodes in order to support their own short-range communications. We prove that the network energy efficiency is independent of the transmitters range and, therefore, that long-range transmitters can supply the power required for short-range connectivity without degrading the overall network energy efficiency. As an example, we have studied the feasibility of a short-range multiple-access return-link powered by the interference harvested from neighboring long-range connections.
