Configurations: Contexts and Statestem, applications have to make sense of raw sensor data themselves. As a remedial solution, we present Open-VSeSeMe, a middleware atop TinyOS that converts raw sensor streams into data units with semantic meaning. These data units can be shared between applications leading to efficient use of resour

However, the GSM-R will become the bottleneck regarding the performance of the ERTMS due to the increase of both the trains’ traffic, and the resources needed by all the applications that contribute to safety in rail transportation and to satisfaction

Message and Live Sequence Chartsaches originates. In the ideal case, such a reference system would yield the exact and continuous 3D baseline between two vehicles at any time in any circumstance. In this paper we will characterize the use of a laser scanner as a reference system for relative vehicle positioning.
