Routing device and method

摘要

Disclosed herein are provided a routing device and method for configuring a Low Power Wireless Mesh Network (LPWMN) including a channel hopping time multiplexing wireless link. The routing device includes a control unit and a communication unit. The control unit sets up a virtual link, a shared link, or a dedicated link to an external device or router. The communication unit forwards a data frame to the device or router based on the set-up link.

1. A routing device for configuring a Low Power Wireless Mesh Network (LPWMN) including a channel hopping time multiplexing wireless link, the routing device comprising:
a control unit configured to set up a shared link using an inward rx timeslot and an inward tx timeslot and a dedicated link to an external device, the dedicated link including an inward dedicated link and an outward dedicated link; and a communication unit configured to forward a data frame to the external device based on the set-up link wherein the shared link and the dedicated link comprise superframes whose beacon interval (BI) has a contention access period (CAP) and a guaranteed time slot (GTS), and a multi-superframe, wherein the routing device is addressed using a cluster tree, wherein the cluster tree corresponds to a cluster ID and the routing device is addressed using a position within the cluster tree, wherein the control unit is configured to set up a virtual link, wherein the virtual link comprises a multi-hop link connected through the routing device which relays a routed transport frame instead of forwarding the routed transport frame.
