The case for DEVS in networking M&S: upload user collaboration in mobile networks using coordinated multipoint

Future mobile networks should provide high data rate services for their customers regardless of their location. This is a challenging task, specifically for the users in the edge of the cell’s area. To overcome this problem, Long Term Evolution Advanced introduced Coordinated Multi-Point. Upload User Collaboration (UUC), presented here, can be combined with CoMP to enhance the upload performance of cell-edge users. This research presents a real-world use of Discrete Event System specifications for modeling mobile networks, and a practical case study with industrial relevance (algorithms, based on the DEVS studies, were patented by Ericsson Inc. for commercialization). The study compares three approaches: UUC, CoMP, and a non-cooperative algorithm. The simulations show that UUC provides significant improvements to the cell-edge users’ upload performance, and it reduces the time required to upload a file.
