Enhanced SRTST - Optimized Intra-Car Real-Time Wireless Sensor Communication

In-vehicle wireless sensor/actuator networks are subject to QoS requirements for real-time performance. We show how these requirements can be met, especially for randomly distributed traffic, by our improvements of the Soft Real-Time Shared Time Slot (SRTST) MAC protocol.

Summary:In-vehicle wireless sensor/actuator networks are subject to QoS requirements for real-time performance. We show how these requirements can be met, especially for randomly distributed traffic, by our improvements of the Soft Real-Time Shared Time Slot (SRTST) MAC protocol. The improvements target the upper delay limit of prioritized messages and achieve a bounded delay within the delay requirements for such messages. We performed simulations with the discrete event simulator OMNeT++ of our improvements and compared them to the original MAC protocol.
