LL Simple Wireless
The LL Simple Wireless model is an ns-3 model that extends the functionality of the base ns-3 Simple Wireless model. The base Simple Wireless model has limitations to its functionality that prevent it from providing a realistic model of physical layer packet deliver. For example, that model assumes that a physical link has infinite bandwidth and that delivery of packets at a given range is all or nothing.
The LL Simple Wireless model adds a set of features to the base Simple Wireless model to address and overcome the limitations of the Simple Wireless model and provide a more robust and representative model of physical layer packet delivery. The features added to the SimpleWireless model to create the LL SimpleWireless model include
- Error models: Constant error rate, packet error rates based on a user provided curve, and stochastic errors
- Packet queuing (including control and data sub-queues)
- Transmission delay
- Fixed contention
- Simulated directional networking
- PCAP packet capture
With the exception of the transmission delay, all of these features are optional and are not required to be enabled. Thus, if a user wants the behavior of the original Simple Wireless model, this can be accomplished by not enabling these new features.
