Effect of User Distribution on the Capacity of Cellular Networks
نویسندگان
چکیده
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.

Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...

Abstract: The development of distributed generation (DGs) units in recent years have created challenges in the operation of power grids, especially distribution networks. One of these issues is the optimal allocation (location and capacity) of these units in distribution networks. In this thesis, a method based on the improved ant colony optimization algorithm is presented to solve the problem ...
متن کاملImpact of Interference Model on Capacity in CDMA Cellular Networks
An overwhelming number of models in the literature use average interference for calculation of capacity of a CDMA network. In this paper, we calculate the actual peruser interference and analyze the effect of user-distribution on the capacity of a CDMA network. We show that even though the capacity obtained using average interference is a good approximation to the capacity calculated using actu...
