The Study on Power Consumption Models for Low-Power Wireless Communications

Abstract

Power consumption models for low-power wireless communications, where transmitter and receiver electronics power consumption is comparable to PA power consumption, are based on channel path loss, depending on distance between transmitter and receiver, making them suitable for energy-efficiency consideration of multi-hop vs. single-hop communication. We propose L – model, based on total channel-loss, that is more suitable for transmission energy consumption optimization in the sense of different modulation and coding techniques than d – models. Since total channel loss information is available at current transceivers in terms of RSSI and LQI, L – model is more suitable for TPC techniques optimization than d – models.
