ASOS-IV: A Smart Sensor Network Software Platform for Intelligent Vehicles

Intelligent vehicle applications, which smart sensor network technology can be used widely, have several rigorous requirements, such as real-time constraint, low power-consumption, resource limitation, self-adaptation and robust operation. In order to facilitate the development of smart sensor network applications in intelligent vehicle systems, a smart sensor network software platform named ASOS-IV is developed in this paper, which consists of an reliable real-time OS kernel for smart sensor nodes and an energy-efficient and reliable routing protocol for wireless communications between sensor nodes. Detailed simulations and analysis results indicate that ASOS-IV is a reliable real-time software platform for intelligent vehicle applications, which can improve energy efficiency, balance energy consumption of all sensor nodes and enhance system fault tolerance.
