SUMMARY Collisions and interferences among nodes pose a challenge for data aggregation in many applications, such as target tracking by adopting dynamic convey tree‐based collaboration (DCTC). Because coordination with a time division multiple access (TDMA) medium access control (MAC) might provide an opportunity for better interference control, in this paper, we refine slot allocation to nodes in a dynamic convey tree and design an energy efficient MAC protocol called dynamic‐time division multiple access (D‐TDMA). The D‐TDMA protocol avoids collisions and interferences and allocates contiguous active slots to nodes as far as possible during data aggregation from leaf nodes to a root node. As a result, energy consumption in switching from sleep to active state is saved. In comparison with Always‐On scheme, theoretical analysis results show that the proposed protocol D‐TDMA improves energy efficiency by up to 28.3% during one data aggregation. Furthermore, simulation results show that D‐TDMA does not suffer from collisions and interferences among nodes in a dynamic convey tree and performs similar throughput to that of Always‐On scheme. Because of its advantage of parallel and continuous scheduling among node pairs in the convey tree, D‐TDMA outperforms efficient slot reservation in both energy efficiency and low delay because of to slot saving.
