[Ns-developers] turning nodes on/off - failure/recovery models

[Nils Aschenbruck]

Hi all,

it would be great if ns-3 could support switching on/off nodes.

There are at least two reasons:
i) in reality this may happen
ii) one of the core characteristics of MANETs it is to be able to deal with
nodes leaving and (re-)joining the network

Thus, I think it would be great, if ns-3 could support this.
A node that is switched off should of course not send any messages on any
layer. In general, this would mean introducing node or device failure/recovery
models to ns-3.

If it is supported I think it would be a nice-to-have to support it with and
without node reset. There may be scenarios where one wants to simulate a fixed
number of nodes that are switched on and off. But there may also be scenarios
where one wants to simulate that some nodes leave and other nodes do later join
the network. If "switch on with reset" would also be supported, one could use
the same nodes that were switched off before in the latter case.

Thanks for your work on ns-3,
best
Nils
