SNMP agent for on-board-units in vehicular systems
| Resumo: | On average over 60 Million automobiles are sold every year in the whole world and at one point or another every single one of these vehicles will require some form of maintenance to be performed. With the ever increasing complexity of these vehicles, any maintenance job has also increased in its difficulty and time required to complete, as such there is a need for a set of fast and reliable diagnostic tools to speed up this process. Furthermore, with the ever closer introduction of Vehicular ad hoc networks (VANETs), there is a need for an application that is able to read sensor data in real time and change the state of actuators in a vehicle with minimum delay, allowing for the introduction of such methods like platooning, which require several vehicles of different types and models to accelerate or brake simultaneously while also allowing a closer headway between vehicles, since the reaction time of such a system would be entirely based on the latency of the communication method/protocol being used and not the capabilities of the human driving the vehicle. As such. the main objective of this project is to create and test a Management Information Base (MIB) specification to be implemented on an Simple Network Management Protocol (SNMP) agent inside an On-Board-Unit (OBU) that allows a company or individual to quickly and safely access all information gathered from the vehicles’ own sensors while also allowing for its configuration and, at the same time, managing errors in the system. This system will make use of the preexisting Controller Area Network (CAN) technology to access and gather data from a vehicles sensors so that it can be accessed in real-time through an application. Such an application will communicate with the vehicles OBU using SNMP. This solution should be capable of handling more requests for data than already existing standard technologies and protocols, such as On Board Diagnostics (OBD-II), while also being faster than them. Additionally a way for users or other entities in a VANET to activate/ deactivate specific actuators should also be included in this solution as such a feature is vital to the introduction of methods like platooning. |
