In this paper, we investigate TDM-based resource schedule issue for collision avoidance in clustered Ad Hoc multicast network. Two kinds of time-division schedule scheme are proposed, the Single-cluster Transmission per Slot (STS) scheme and Multi-cluster Transmission per Slot (MTS) scheme applying the slot scheduling algorithm we present. In order to increase transmission efficiency, an adaptive power assignment scheme is proposed. The simulation results show that both STS and MTS outperform the Conventional Collision-Retransmission scheme in throughput. And MTS can achieve more benefits with power concerned.In this paper.
