Abstract: A method and an apparatus for communication between peer devices in which a cyclic-superframe including a plurality of superframes is used are provided. The method may include: receiving a discovery request command frame including information about a first cyclic-superframe for a peering period at an active contention access period (CAP) of the plurality of superframes; transmitting, to a peer device that has transmitted the discovery request command frame, a discovery response command frame corresponding to the discovery request command frame; and performing the peering period with the peer device based on the first cyclic-superframe.

Abstract: Disclosed herein is a routing apparatus and method for configuring a LPWMN based on a channel hopping time-multiplexed wireless link. The routing apparatus of the present invention includes a control unit for setting up a channel hopping time-multiplexed wireless link with a gateway router, one or more routers, and one or more devices based on deterministic and synchronous multi-channel extension (DSME) media access control (MAC) link control (DSME MAC link control: DLC) sublayers and DSME MAC link network (DLN) sublayers. A communication unit transfers data frames to the gateway router, routers, and devices depending on connection quality of the channel hopping time-multiplexed wireless link.
