Title
Simulation Based Study Of Adaptive Rate Scheduling For Multi-Operator 3g Mobile Wireless Networks
Abstract
For current and next 3G and beyond wideband code-division multiple access (WCDMA) cellular networks, sharing the radio access network has become an important issue for 3G mobile operators. Sharing of network infrastructure among operators offers an alternative solution to reducing the investment in the coverage phase of WCDMA. In radio access network (RAN) sharing method, which is our focus in this study, each operator has its own core network and only the RAN is shared. It implies that multiple operators fully share the same RAN. This paper tackles an uplink efficient scheduling to provide maximum system throughput and proportional fairness in accordance with operator capacity share through adaptive resource allocation scheme. We refer to this new scheme as Multi-operators Code Division Generalized Processor sharing scheme (M-CDGPS). It employs both adaptive rate allocation to maximize the resource utilization and GPS techniques to provide fair services for each operator. The simulation results show that the proposed scheme improves both system utilization (throughput) and average delays.
