Radio frequency (RF) based wireless charging and information transfer, also known as simultaneous wireless information and power transfer (SWIPT), is a new paradigm of green-energy wireless communications. In this work, we apply SWIPT to cooperative communication networks where each relay is equipped with an energy harvesting (EH) circuit to extract and convert the RF signal into useable energy for...
Several asynchronous duty cycle MAC protocols have been proposed for low power in the wireless sensor networks. However, these proposed MACs pay little attention on the performance degradation in many-to-one communications which is the most common traffic pattern in wireless sensor networks. In this paper, we propose AB-MAC, an appointment based MAC protocol to overcome the effect of channel contention...
