We have better protocols in IOT for application layer like CoAP, MQTT. But there are some limitations of these protocols like CoAP is having an issue with multicasting and broadcasting where's MQTT has an issue with the unlimited number of node handling which in turn is producing lot of delay due to packet loss and some issue it had with Security.
My question is
is there any group which is working on such a protocol which can either be hybrid or be adaptive to handle all such issue without any custom interference. Please enlighten!
