Embedded WiMAX-based vehicular router for Telematics computing

This study presents a novel embedded WiMAX-based vehicular router with a network mobility architecture that promotes the Telematics services for Ubiquitous/Pervasive Computing (UPC) environment anytime and anywhere. Each Telematics user has to process the handoff procedure with the mobile IP mechanism. Therefore, the proposed WiMAX-based vehicular router can process more Telematics users for handoff procedures simultaneously. Network performances in terms of packet loss, round-trip time (RTT) and handoff latency are investigated and analyzed in this study. Compare with the traditional WiFi-based vehicular router, the embedded WiMAX-based vehicular router improves the packet loss about 36% and the average RTT is decreased by approximately 34%. Based on the handoff latency analysis, the embedded WiMAX vehicular router has the superior performance using the mobile network with the embedded router when there are more than two Telematics users.
