ABR MESSAGE TRANSFER SC IN WIRELESS ATM NETWORKS

Wireless ATM networks are motivated by an antici- pated demand for wireless extensions of the integrated multi-media services. In this paper, a TDMA-based wireless ATM is presented for the integration of wireless access with wired B-ISDN/ATM net- works. The presented system is characterized by a reservation-based access protocol to handle diverse services and a dynamic duplexing scheme for TDD to support uplink/downlink asymmetric traffic. Resource allocation algorithms which aim at prorating the shared radio resources among ABR message traffic such as files and e-mails are also presented. Simulation results show that the Equal Sharing algorithm where the resources are equally shared among all mo- bile terminals can provide higher average and lower variance of the throughput than the FIFO-based algorithm.
