Summary :

Recent technology innovations have increased the study on wireless LAN (Local Area Network). Also, improved computing power of end user has needed the distributed communication environment. However, conventional access protocols (TDMA, CSMA/CA and CDMA) have some problems such as the degradation of channel utilization, necessity of control station and code reuse. Therefore, we propose new multiple access scheme, Hybrid Reservation CDMA based on our previous work, DR-CDMA. Proposed method for distributed/central wireless LAN architecture provides, distributed channel access mechanism, code reuse method and internetworking method with conventional wire-based LAN. In proposed mechanism, efficient channel utilization could be obtained by minimizing overhead. Also, variable length frame from upper layer could be transmitted without segmentation. Moreover, nodes are serviced based on priority. In view of management, insertion of new node could be done easily in proposed HR-CDMA in proposed method due to its variable length property which can encapsulate conventional LAN frame. According to computer simulation, it has been shown that performances of proposed method are better than those of reservation TDMA bitmap protocol with respect to delay and throughput characteristics in the distributed environments as well as interworking environments between wire and wireless LAN.
