Traffic aided fair scheduling using compensation scheme in CDMA cellular networks

Fair queuing has long been a popular paradigm for providing bounded delay channel access and separation between users in wired networks. However, adapting fair queuing to the wireless domain is not a trivial task because of the unique problems in wireless channels such as location dependent and bursty channel error. In this paper, we incorporate traffic information into wireless fair scheduling using compensation scheme. In particular, we first establish general properties for fair scheduling using proportional compensation scheme in CDMA cellular networks. It distinguishes the services in different application levels. A compensation model and a reallocation method in the scheme were introduced to achieve wireless fair services. Then, we develop a new traffic aided fair scheduling scheme based on compensation model by making use of rile size information. Extensive simulation results show that our scheme can operate well in CDMA cellular networks.
