Abstract:
High speed vehicular communication using localization technology
with millimeter wave (mmWave) wireless communication is one of
the promising technology. The low level Vehicle to Vehicle (V2V)
communication standards are all incompatible with handling data
rates at Gbps level. mmWave communication handles multi-Gbps
data rates but it is sensitive to blockage. To overcome this blockage
problem, directional antenna is used but it leads to beam misalignment because of doppler effect. When there is a high mobility, the
conventional method of beam sweeping is ineffective because of searching and recovering actions that frequently result in beam alignment
issues. In this thesis, considering beam misalignment in localization
technology errors. We design and analyze by the proposed Particle
Swarm Optimization (PSO), Grey Wolf Optimizer (GWO) and Hybrid Particle Swarm Optimization Grey Wolf Optimizer (HPSOGWO)
optimization algorithms. The proposed algorithm are a fine beam
alignment without searching steps taken before steering the beam
to the estimated vehicular position caused by localization errors.
The simulation results show that HPSOGWO has better average
maximum throughput performance than GWO by 1.96% and PSO
by 12.82%. GWO has better throughput performance than PSO by
11.07%. The result also show that HPSOGWO significant throughput
improvements and fastly converge to the optimal value.
