Abstract

The use of smart antenna systems in WiMAX vehicular communications increases the coverage and throughput thus reducing the infrastructure costs, creates the lower levels support for new high level innovative services and may increase applications security. However, new challenges appear related to interference range, neighbor discovery, mobility management, scheduling issues, in addition to some already existing ones as base station (BS) coverage and bandwidth availability, velocity versus application throughput, and service availability/continuity. The paper continues a complex study related to WiMAX vehicular communications evaluation and optimization, focusing on simulations of a real smart antenna in WiMAX vehicular environments.
