A fair scheduling discipline for cellular data services with location-dependent errors
Ming-Hua Yao, Jiann-Liang Chen, Hao-Chin Cheng · 2002
To provide cellular data services with differentiated QoS in a high data error-rate environment, a /spl lambda/-WFQ scheduling discipline, based on the WFQ mechanism and LaGrange /spl lambda/-calculus was developed. The air resources are allocated using /spl lambda/-calculus and the WFQ mechanism is then responsible for the transmission scheduling. The /spl lambda/-WFQ discipline compensated for the penalty derived from the location-dependent errors using the equivalent efficiency concept. This discipline can generate a fair schedule for a diverse mix of traffic with diverse QoS requirements in a limited radio spectrum. The experimental results show that as much as a 5% improvement in the mean acceptance rate is obtained relative to the other existing WFQ-based schemes at the expense of a small blocking performance.
