In this paper, the efficiency of transferring non-realtime data over Wireless ATM (WATM) networks is studied. Non-realtaime services are sensitive to bit error as well as cell loss. The loss or error of a single cell due to congestion or a line error will result in the retransmission of the entire protocol data unit (PDU) by the end user in ATM networks. In watm, cells are subject to the influences of noise. In this paper, we propose an adaptive cell checking controller (ACCC) for WATM networks to early find out error PDUs and to drop all remaining cells of these frames. The proposed ACCC only needs several bits over-head for each PDU of size of several Kilobytes. The removable percentage of an erroneous PDU by ACCC is analyzed. Simulation results show that compared with a conventional early packet drop mechanism, the proposed ACCC can achieve superior network utilization while keping the minimum overhead in WATM networks.
