Improving the efficiency of link layer resource allocation in cellular systems via controller

In this work, we aim to investigate the efficiency of link layer resource allocation when a device which is called controller is used behind the base stations. By using this device, base stations are collaborating, in other words, a mobile user can be connected to more than one base station simultaneously. It is expected that this design improves the throughput and quality of service (QoS). In this study, we investigate the throughput of the system along with a performance of a video transmission. We considered the 5 cases, which are traditional case, where a user can only connected to a one base station, and 2, 4, 6, 7 base stations are collaborating. We run the simulations to observe and compare the results of the cases for mobile clients.
