In packet radio networks with TDMA, the throughput performance of network should be degraded due to the unequal traffic of each user. To overcome this problem, Mini-Slotted Alternating Priorities (MSAP) and TDMA with Parallel Transmission (TDMA/PT) were proposed. Especially, TDMA/PT can attain the thorughput performance more than one, even under unequal traffic. However, TDMA/PT cannot be used for mobile networks, because each terminal should know the location of every other terminal. In this paper, we propose an entirely new protocol named Slot Reservation TDMA with Parallel Transmissino: SR-TDMA/PT," which is suitable for mobile networks because a central station is able to locate every terminal easily. The central station also reserves time slots for each terminal so as to transmit packets in parallel as much as possible. Therefore, the throughput performance of SR-TDMA/PT is higher than TDMA/PT. We describe SR-TDMA/PT in detail and evaluate the performance of this protocol by simulation under various conditions.
