Abstract
To achieve high-speed (giga-bit) connectivity for short-range wireless
multimedia applications, the millimeter-wave (mmWave) wireless personal area
networks with directional antennas are gaining increased interest. Due to the
use of directional antennas and mmWave communications, the probability of
non-interfering transmissions increases in a localized region. Network
throughput can be increased immensely by the concurrent time allocation of
non-interfering transmissions. The problem of finding optimum time allocation
for concurrent transmissions is an NP-hard problem. In this paper, we propose
two enhanced versions of previously proposed multi-hop concurrent transmission
(MHCT) schemes. To increase network capacity, the proposed schemes efficiently
make use of the free holes in the time-allocation map of the MHCT scheme; thus,
making it more compact.
