WiMAX for Traffic Control in Urban Environments

Abstract

This chapter addresses the wireless communication aspect of traffic control in an urban vehicular environment. The IEEE 802.16e-2005 standard is used for Infrastructure to Vehicle communication. An architecture is developed with the target of minimizing overall data loss. Access Service Network Gateway (ASN-GW) is used to manage vehicle communication while roaming. OPNET simulations show that using ASN-GW gives good performance in mobility management. Simulations also show that introducing an interference source drastically degrades system performance. Using Dual Trigger HO (DTH) in a congested scenario improves system performance and reduces the impact of interference on the system.
