Performance evaluation of a vehicle position reporting system for hazardous goods monitoring.

This paper evaluates the performance of a shared satellite based system which tracks the positions of a large number of vehicles carrying hazardous loads across a wide and diverse geographical region. The power with which the vehicle's transmission is received is related to the vehicle's position. A model for this situation is formulated to show that the utilisation of the capacity of the low access delay satellite links is not fairly distributed amongst the vehicles in different areas. The approaches which aim to DRIVE the system towards an optimal operating point and to equalise the performance distribution between groups of vehicles in different operating environments are identified.
