Abstract
A method for transmitting data to and from nodes of a multi-hop network with a Time Division Multiple Access (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.
