Abstract

This letter studies energy harvesting systems, which perform peer discovery. Wireless peer discovery is a network operation performed to identify the existence of peers in the network. In this operation, some fractions of the peers broadcast the discovery message to nearby peers. In such a system, a receiver decodes the message while harvesting energy from the received signal through the power splitting circuit. An optimization problem is examined for maximizing the harvested energy in the peer discovery network with an arbitrary value of the path loss exponent. A low-complexity algorithm is proposed, which utilizes bisection search. The numerical results demonstrate that the proposed algorithm achieves almost the same performance as the optimal exhaustive search algorithm with much reduced complexity.
