Enabling space time division multiple access in IETF 6TiSCH protocol
TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2019 IETF 6TiSCH standard aims to create reliable, deterministic, and low-power networks by scheduling bandwidth resources in time and frequency domains. The main emphasis of 6TiSCH protocol is that it creates Internet of things (IoT) networks with a deterministic and controllable delay.

Time-Reversal based Power Division Multiple Access
Wireless NetworksAbstract This paper proposes time-reversal based power division multiple access (TRPDMA) to enhance achievable sum rate (ASR) in dense multi-path environment. In TRPDMA, time-reversal (TR) introduces spatial focusing effect which provides a robustness of transmission using channel reciprocity.
