Hello Janna, another approach (depending on your use case) to limit the number of sensor nodes that can communicate with each other is to use a link-layer black-/whitelisting. In RIOT, you can use the l2filter_whitelist, or l2filter_blacklist module respectively for this.
When you compile these in, then you will get new shell commands to interact with these lists. You can get a glimpse on the programmatic usage e.g. here [1]; the doc here [2].
