A power-controlled coded slotted ALOHA

Abstract

This letter proposes a power-controlled coded slotted ALOHA (PC-CSA) for reliable wireless networks. The proposed PC-CSA introduces the concept of the randomization of the transmission power control mechanism in CSA to achieve reliable packet receptions at base stations. We conduct computer simulations and confirm that the proposed PC-CSA can improve the packet loss rate under a predefined time constraint.
