In this letter, we consider the control of an energy self-sufficient receiver in a multi-access network with simultaneous wireless information and energy transfer. Multiple trans- mitters send data to a common receiver whose only source of energy is a finite size battery which is recharged only from the energy harvested from incoming RF signals. The nodes access the channel randomly resulting in a packet collision when multiple transmitters simultaneously access the channel. The receiver takes samples from the received RF signal to calculate the probability of a collision. The objective is to maximize the receiver goodput subject to the instantaneous availability of receiver energy. We develop an asymptotically optimal dynamic control algorithm, where the receiver makes an energy harvesting or decoding decision according to the current channel measurements and battery level.
