Abstract
In vehicle-to-vehicle safety messaging, periodic safety messages can be used for safety applications. These applications require low latency and high probability of reception, however there can be a problem with unsuccessful reception due to collision of these safety messages when there are sufficiently large amount of vehicles and/or repetitions. Literature proposes repetition based broadcasting to increase reception probability, while decreasing average reception delay; however this increases the probability of packet collision and overall network traffic. In this thesis, we introduce a new cross-layer design, which allows for collision correction of safety message repetitions for further improving probability of reception. We describe our design as well as simulation using various repetition schemes under different packet error rates and compare our cross-layer collision correction method with non-collision correcting performance. Once implemented, this new approach can substantially improve the reception likelihood of safety messages, without loss of latency, and potentially make active vehicle safety applications more responsive.
