In this paper, we consider the potential use of adaptive arrays to improve the performance of multihop-RTS MAC protocol. In addition to this, we proposed to improve the performance of this MAC protocol by using two omni-directional control packets. These control packets are busy node list (BNL) and overall link state table (OLST). The performance of the protocol is evaluated and compared with existing MMAC that uses switched-beam antenna and IEEE 802.11. The results show that MMAC can produce improvement in throughput when using adaptive arrays and the two omnidirectional control packets.
