Summary:
This paper measures the effect of transmission range on the connectivity for the vehicular telematics network. A discrete event simulator has been implemented to trace the movement of each vehicle, not using a simulated movement model but genuine movement data. The connectivity is analyzed by performing the Dijkstra's shortest path algorithm from each vehicle to a stationary gateway in multi-hop base. The experiment result indicates that the transmission range, having the great impact on the connectivity, can achieve up to 70 % connectivity on the common parameter values. The connection lasts mostly for about 2 minutes. This result provides a guideline to design a new location-based service.
