Abstract: Provided are methods of operating a gateway and a server, performing an intelligent negotiation in an Internet of Things (IoT) network. According to an example embodiment, a method of operating the gateway of an IoT system includes receiving status information from at least one of a plurality of end devices included in a local network, determining whether to start a negotiation based on a status of the local network that is analyzed based on the status information, transmitting a negotiation request to an external device, receiving a suggestion corresponding to the negotiation request from the external device, and transmitting a reply indicating whether to accept the suggestion to the external device.

Abstract: A method, apparatus and/or system of selecting a routing in an asymmetric link, in which an arbitrary intermediate node of the at least one intermediate node receives routing request information including a first link quality for a path from the source node to the arbitrary neighbor node from an arbitrary neighbor node of the arbitrary intermediate node, acquires a second link quality for a path between the arbitrary intermediate node and the arbitrary neighbor node, acquires a third link quality based on the first and second link qualities, updates the first link quality in the routing request information with the third link quality, and broadcasts an updated routing request information to other neighbor node for the destination node to determine at least one of a desirable forward path or a desirable backward path from the source node to the destination node, may be provided.
