Abstract EN
The Industrial Internet of Things (IIoT) is the use of Internet of Things (IoT) technologies in manufacturing.
The vehicular ad hoc networks (VANETs) are a typical application of IIoT.
Benefiting from Dedicated Short-Range Communication (DSRC) technology, vehicles can communicate with each other through wireless manner.
Therefore, road safety is able to be greatly improved by the broadcast of safety messages, which contain vehicle’s real-time speed, position, direction, etc.
In existing DSRC, safety messages are broadcasted at a fixed frequency by default.
However, traffic conditions are dynamic.
In this way, there are too many transmission collisions when vehicles are too dense and the wireless channel is underused when vehicles are too sparse.
In this paper, we address broadcast congestion issue in DSRC and propose lightweight adaptive broadcast (LAB) control for DSRC safety message.
The objectives of LAB are to make full use of DSRC channel and avoid congestion.
LAB meets two key challenges.
First, it is hard to adopt a centralized method to control the communication parameters of distributed vehicles.
Furthermore, the vehicle cannot easily acquire the channel conditions of other vehicles.
To overcome these challenges, channel condition is attached with safety messages in LAB and broadcast frequency is adapted according to neighboring vehicles’ channel conditions.
To evaluate the performance of LAB, we conduct extensive simulations on different roads and different vehicle densities.
Performance results demonstrate that LAB effectively adjusts the broadcast frequency and controls the congestion.
