For local wireless communications, the packet reservation multiple access (PRMA) protocol, which combines random access with time division access, has been proposed and analyzed. The study results shows that the performance of PRMA is degraded in the heavy load condition because of the contention mechanism of random access. In this paper, we propose the use of the adaptive array antenna with PRMA protocol to improve the performance. In the proposed model, the adaptive array can acquire a packet by pointing peak antenna pattern toward that packet even when a collision occurs. We evaluate the throughput performance by the theoretical analysis. We also evaluate the throughput and the packet dropping probability by the computer simulation. It is shown that the proposed model attains higher throughput and lower packet dropping probability than the conventional PRMA.
