Abstract A topology-transparent Time Division Multiple Access (TDMA) with reservation for MIMO link is proposed for multi-hop Ad hoc networks in this paper. By reservation each node transmits simultaneously all data streams in its assigned collision-free slots and utilizes free slots among other non-assigned slots and its assigned collision slots by probability to transmit a part of all data streams. The protocol is suitable for distributed application since it need not know the whole network topology information. Through theoretical analysis, the minimum throughput and optimal frame length are derived. The results show that the protocol is robust to topology change.
