In this paper, we present a TDMA MAC protocol for scenarios with real-time traffic like voice streams. While many previous works assume stationary networks, DynaMAC can quickly adapt to changing topologies while not violating delay guarantees for even a single data packet with high probability. By intelligent data aggregation, DynaMAC also accounts for the fact that the large synchronization preambles of high-speed PHYs make transmissions of very small packets like voice samples extremely inefficient. Further, it introduces a novel segmentation concept, which results in a discrete set of potential per-node delay guarantees, which can be exploited by higher layers to balance the endto-end delay of routes with different lengths. Finally, the slot allocation strategy tries to ensure a contiguous placement of unassigned slots, so that larger best-effort packets can be efficiently transmitted with a minimum of fragmentation. We validate our propositions with expressive simulations. |
