Effect of User Distribution on the Capacity of Cellular Networks
Xue Tang, Hongwen Yang · 2012
User distribution is a critical issue in cellular networks.In most previous works, a uniform user distribution is often assumed within a cell.In this paper, we purpose a non-uniform user distribution model.Both its effects on downlink and uplink capacities of a cellular network are evaluated under two common packet scheduling algorithms: Maximum Carrier to Interference scheduling and Round Robin scheduling.Simulation results show that when user distribution center coincides with cell center, the higher the user concentration, the larger the system capacity.And when user distribution center deviates from cell center, the loss of system capacity is much greater at higher user concentration.
