Executive Summary

Updating software in vehicle Electronic Control Units (ECUs) will become a mandatory requirement for a variety of reasons, for examples, to update functionality of an existing system, add new functionality, remove software bugs and to cope up with ITS infrastructure. Since multicasting is the most efficient method of group communication, updating software in an ECU of a large number of vehicles could benefit from it. In a previous work, the authors proposed an infrastructure-based mobile multicasting for Remote Software Upload (RSU) in vehicle ECUs where an ECU receives the software from a remote software distribution center using the road side Base Stations (BSs) as gateways.
