Abstract

We proposed novel hybrid FSO/RF architecture¹ to provide broadband wireless access to end users. To provide quality of service (QoS) bounds for different types of traffic(voice, video and data) we proposed some fair queuing algorithms^2,3 ,but because of the hybrid wired and wireless links there can be certain times allocated to a host when that host is unable to transmit data because of wireless link errors. These wireless link errors are location dependent and bursty. The channel errors can occur from multi-path fading, shadow fading or interference from another device. In this paper we proposed a novel fair queuing algorithm to provide end to end QoS bounds to the end users for the proposed architecture .The algorithm provide QoS bounds for Ethernet traffic in the wired domain as well as in wireless domain with compensation for wireless link errors. Scheduler maps priorities and weights for QoS of the Ethernet traffic into wireless MAC. By supporting existing Ethernet traffic QoS parameters ^4-7, scheduler avoids the need to redefine QoS parameters for wireless channel. By simulations and analysis we proved that the algorithm guarantees (1) delay and throughput for error-free flows, (2) short term fairness among error-free flows, (3) long term fairness among errored and error-free flows,(4) graceful degradation for leading flows and graceful compensation for lagging flows. Each connection QoS is guaranteed by calculating bounds on delay and reserving the Bandwidth (BW).
