Energy Harvesting Ad Hoc Networks

This chapter focuses on the ad hoc networks, where multiple energy harvesting (EH) nodes are deployed in a given area and try to utilize the shared wireless channels via opportunistic access. It proposes a distributed opportunistic scheduling (DOS) framework with the two‐stage probing and the save‐then‐transmit energy utilization schemes to fully utilize both the energy state information (ESI) and channel state information (CSI) at each node and employ an optimal stopping framework to solve the expected throughput maximization problem for the considered network. The chapter studies the multiuser gain with the emphasis on energy diversity, where the scaling law of the expected throughput over the number of users is investigated. The access schemes discussed in this chapter capture the "energy‐accumulating" feature in EH communications, and the corresponding throughput scaling sets the guidelines for the future transmission design of EH wireless systems.
