Abstract: Disclosed herein are a multicast apparatus and method. In the multicast method, a multicast apparatus searches one or more communication objects in a distributed network environment. Multicast data is received from a sender-side communication object among the one or more communication objects. A polling message is received from the communication object that transmitted the multicast data. A response message corresponding to the polling message is sent. It is determined whether a transmission error has occurred between communication objects based on results of sending of the response message, and multicasting is performed based on results of determination.

Abstract: A communication method and an IoT device in a multi-MAC (Media Access Control)-operating environment. The communication method in the multi-MAC-operating environment, including synchronous MAC and asynchronous MAC, includes periodically transmitting, by the IoT device included in the multi-MAC-operating environment, a first message to a first device; determining, by the IoT device, whether to transmit a second message; transmitting, by the IoT device, a preamble packet to a second device, to which the second message is to be transmitted, when the second message is determined to be transmitted; and transmitting, by the IoT device, the second message to the second device.

Abstract: Disclosed herein are a dynamic scheduling method for guaranteeing Quality of Service QoS depending on network transmission traffic and a system using the same. The dynamic scheduling method includes assigning communication channels to respective nodes based on Identifications (IDs) of parent nodes corresponding to the respective nodes, setting priorities for assignment of time slots to the respective nodes in each quarter based on data traffic volumes corresponding to the respective nodes, and assigning time slots to the respective nodes in each quarter depending on the set priorities for assignment of the time slots.

Abstract: Disclosed herein are an apparatus and method for generating a Quality of Service (QoS) profile. The apparatus includes a user interface unit, a resource QoS policy generation unit, a traffic QoS policy generation unit, and a QoS profile generation unit. The user interface unit receives a QoS policy for Data Distribution Service (DDS) from a user. The resource QoS policy generation unit collects resource data for a device that performs the DDS, and generates a QoS policy for handling resources using the collected resource data. The traffic QoS policy generation unit collects traffic data for a network via which the DDS is performed, and generates a QoS policy for handling traffic using the collected traffic data. The QoS profile generation unit generates a QoS profile based on the QoS policy received from the user, the QoS policy for handling resources, and the QoS policy for handling traffic.
