I assume that there is a very lightweight sensor node. The node wakes up on every 1 min and measures the temperature and broadcasts measured value and sleep again. This node does not have any memory and does not receive any message from other nodes. I want to bring coap message to this node. I know that OBSERVE draft in coap is one candidate. However, it require that the sensor node (coap server) should have availity to receive coap client's request(register) and the memory to remember token from request and client address. But I do not want to make the lightweight sensor node complex. For this kind of node, Do we need make a special mechnism? i.e., we define broadcast or preconfigured response without request. The response may have own uri to describe what data is.
