Abstract :
This paper proposes a novel Spatial-multiplexing Time Division Dynamic Token Protocol (STDTP) in single channel that is based on token-passing scheme with the incorporation of TDMA and spatial-multiplexing. The protocol introduces a token relay algorithm which is fast and adaptive to topology variation, presents a collision avoidance algorithm which solves the exposed and hidden terminal problem through the information of network topology and active data transmission carried by the token. The protocol improves the spatial multiplexing compared with the RTS/CTS access mechanism. The results of the simulation show that STDTP can significantly improve the throughput.
