When a network has more traffic than it can handle, congestion occurs: IOTA Congestion Control Algorithm ICCA avoids overwhelming nodes by scheduling selected messages at a constant rate to be distributed across the Tangle.
There is no need for everyone to understand the IOTA congestion control algorithm; it is the technical part of the technology. End-users need not necessarily know about it.
For those who want to understand the technical side of things, gossiping is how information is passed on in the DLT. The nodes in the network receive messages from one neighbor and then forward them to other neighbors. Since nodes receive a lot of messages, they need to ultimately decide which message they will relay to their neighbors and in what order they have to relay the message. The congestion control algorithm makes a decision at this point in time.
Congestion happens when there is more traffic than what the network can actually handle. In the absence of congestion control, the network will become oversaturated, and it will stop functioning. This is because nodes will overwhelm their neighbors with more messages than what they can practically handle. Oversaturation is prevented by the congestion control algorithm as it decides which message to send or not send.
Congestion control is a difficult problem to handle. It should fulfill conditions like fair access, attack resistance, and consistency.
They have mechanisms in place to choose the leaders who will mine the blocks. The leader is chosen in proportion to the hashing power or the stake amount. The access is limited to leaders, and even during an attack, congestion becomes impossible.
Blockchains follow a consensus module to choose a leader. Since the access is limited to leaders, the access is easier in PoW and PoS. Those who want to know more can read the detailed technical document.
IOTA expressed: “The IOTA Foundation will be the core technology provider for SUSEE (Secure Sensor Platforms for Smart Energy Networks).”
This is facilitated by a collaboration between the energy distribution network operator SWO Netz, the two research institutes Fraunhofer FIT/IPT, the university TU Chemnitz, and the SMEs peerOS, mCloud Systems, and TIP, to develop a scalable solution to help with reliable and secure data transmission and processing in sensor networks.
Climate-friendly energy supply at affordable prices is the current requirement. A solution in this regard should scale and also support several sensor devices. It should be feasible at low cost. New digital models make this possible. This collaboration facilitates the technology.
