In this paper, we aim to boost the spacial utilization for the millimeter wave (mmWave) based wireless personal area network (WPAN) by developing a high-speed concurrent transmission (HSCT) scheme using full-duplexed multi-hop relay.We approach this task by two phases, i.e., the routing-path developing and multi-flow scheduling phases, respectively.

In the first phase, we develop the routing path by taking the multiple high-rate hops into consideration.With the aid of full-duplex relay, using multiple high-rate hops can Clothes Rail possibly be more efficient than the low-rate direct transmission.In the second phase, overlapping the scheduling round (SR) can more effectively utilize the full-duplex relay.Conventionally, the SR are arranged in the bumper-to-bumper fashion.

Whereas, overlapping the SR can fully utilize the unoccupied time slots.Moreover, to maintain the transmission rate for the paths via multiple high-rate hops, the scheduling algorithm OREGANUM PLUS properly arranges concurrent transmissions to avoid intolerable amount of interference.Additionally, the variant prioritized flows are taken into account for designing the routing-path developing and multi-flow scheduling algorithms.The simulation results verify the effectiveness of the proposed HSCT scheme.
