Generalized Weighted Fairness and Its Application for Resource Allocation in IEEE 802.16e Mobile WiMAX1,2

Free registration required

Executive Summary

In wireless networks, the definition of fair resource allocation is ambiguous because the wireless channel condition is not constant over time and location. Two main ways to define fair resource allocation are: by number of allocated service time units per user, temporal fairness, or the number of transmitted bytes per user, throughput fairness. In wireless broadband networks i.e., IEEE 802.16e Mobile WiMAX, the quality of services offered by service providers is associated with the price paid. Similar to a traditional cellular phone system, the users may be required to pay air-time charges. The throughput fairness is favorable to customers with a poor channel condition or those at a far distance.
