Detailed Description

A simple channel, for simple things and testing.

This channel doesn't check for packet collisions and it does not introduce any error. By default, it does not add any delay to the packets. Furthermore, it assumes that the associated NetDevices are using 48-bit MAC addresses.

This channel is meant to be used by ns3::SimpleNetDevices.

Config Paths

ns3::SimpleChannel is accessible through the following paths with Config::Set and Config::Connect:

"/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Channel/$ns3::SimpleChannel"
"/NodeList/[i]/DeviceList/[i]/$ns3::WaveNetDevice/Channel/$ns3::SimpleChannel"
"/ChannelList/[i]/$ns3::SimpleChannel"

Attributes

Delay: Transmission delay through the channel
- Set with class: ns3::TimeValue
- Underlying type: Time –9223372036854775808.0ns:+9223372036854775807.0ns
- Initial value: +0.0ns
- Flags: construct write read

Attributes defined in parent class ns3::Channel

Id: The id (unique integer) of this Channel.
- Set with class: ns3::UintegerValue
- Underlying type: uint32_t 0:4294967295
- Flags: read

No TraceSources are defined for this type.
Size of this type is 88 bytes (on a 64-bit architecture).
