Embedded worldwide interoperability for microwave access-based vehicular router for telematics computing

摘要

This study proposes a novel embedded worldwide interoperability for microwave access (WiMAX)-based vehicular router, with a network mobility architecture, that promotes the Telematics services for ubiquitous/pervasive computing environment anytime and anywhere. Each Telematics user processes the handoff procedure with the mobile Internet protocol mechanism. Hence, the proposed WiMAX-based vehicular router can process multiple Telematics users for handoff procedures simultaneously. This study explores and analyses network performances in terms of packet loss, round-trip time (RTT) and handoff latency. The embedded WiMAX-based vehicular router has a packet loss about 36% lower, and average RTT is approximately 34% lower than the traditional wireless fidelity-based vehicular router. The handoff latency analysis indicates that the embedded WiMAX vehicular router has better performance using the mobile network with the embedded router and more than two Telematics users.
