Abstract

This paper investigates an important tradeoff in wireless ad hoc networks concerning the allocation of resources to the PHY and MAC layers. We compare two approaches: One which employs a non-coordinated slotted ALOHA MAC with multi-antenna PHY, and one which employs a tightly coordinated MAC and single-antenna PHY. For both cases, we derive new closed-form throughput expressions. Based on these, we show that using simple slotted ALOHA in conjunction with multiple antennas can provide a higher throughput than fully coordinated access protocols in various practical scenarios. Our results are confirmed through comparison with Monte Carlo simulations.
