Abstract
A method for transmitting data to and from nodes of a multi-hop network with a TDMA scheme is suggested. The network is clustered into N clusters, wherein each cluster of the N clusters has at least one of the nodes. In a first step, the TDMA scheme is organized by periodic superframes. Each superframe of the periodic superframes has a number of frames including at least one broadcast frame and one collection frame for the N clusters. In a second step, one dedicated communication channel is shared by the N clusters within the broadcast frame. In a third step, N separate communication channels are used by the N clusters within the collection frame.
Claims15
A method for transmitting data to and from nodes of a multi-hop network with a Time Division Multiplex Access (TDMA) scheme, wherein the multi-hop network is clustered into a plurality of N clusters and, each cluster of the plurality of N clusters includes at least one node, the method comprising:
- organizing the TDMA scheme into a plurality of periodic superframes, wherein each superframe of the plurality of periodic superframes comprises a number of frames including a broadcast frame and a collection frame for the plurality of N clusters;
- sharing a dedicated communication channel by the plurality of N clusters in the broadcast frame;
- and
- using a plurality of N separate communication channels by the plurality of N clusters in the collection frame.
A device for transmitting data to and from a plurality of nodes of a multi-hop network with a TDMA scheme, wherein the multi-hop network is clustered into a plurality of N clusters and each cluster of the N clusters includes at least one node, the device comprising:
- an organizer for organizing the TDMA scheme into a plurality of periodic superframes wherein each superframe of the plurality of periodic superframes includes at least a broadcast frame and a collection frame for the plurality of N clusters;
- a provider for providing a plurality of N separate communication channels to be used by the plurality of N clusters in the collection frame;
- and
- a selector for selecting one communication channel from the plurality of N separate communication channels to be shared between the plurality of N clusters within the broadcast frame and to assign one of the plurality of N communication channels to one of the plurality of N clusters to be used in the collection frame.
