On the potential of application based Coordinated Multi-point (CoMP)

A Coordinated Multipoint (CoMP) refers to a system where several geographically distributed antenna nodes coordinate to improve performance of the served users in the coordination area, and are connected to each other through dedicated links. One of the main issues that was identified is the backhaul requirements - the type and amount of data to be exchanged among coordinating nodes. We propose and evaluate a new scheme for CoMP - the Application Based CoMP (ACoMP) target on improving application QoS parameters and reducing the communication among the coordinating nodes. In the ACoMP, each node is responsible for a specific sub-set of applications that correspond to some classes of service. Users in the coordination area are served by nodes that support their active applications. Simulation results indicate that the communication between the nodes in this case is negligible, and some improvements in the QoS parameters (throughput, packet-loss, etc.) are achieved.
