Bandwidth Allocation in Wireless ATM Networks with Guaranteed Cell Loss Performance

Wireless ATM aims at extending ATM services to the wireless environment. In contrast to wireline ATM, which is primarily based on reliable fiber optic, wireless ATM will have to cope with an unreliable radio channel. This poses a host of technical challenges related to the provisioning of quality of service (QoS) over a wireless link. Key issues include incorporating the characteristics of the wireless channel in the provisioning of the cell-level QoS, and improving the transport performance using error control mechanisms. In this paper, we analyze the cell loss performance over a wireless ATM link. We consider both cases of a single and multiplexed ATM connections. The link capacity fluctuates according to a fluid version of Gilbert-Elliot channel model. Traffic sources are modeled as on-off fluid processes. Our analytical framework incorporates the effects of error control schemes (i.e., ARQ and/or FEC), which are used to improve the transport performance over the wireless link. For ..
