Performance Analysis of Cloud Radio Access Network using Cross Layer Approach

Radio access technology is conventionally divided into cells with a base station at the centre of each cell servicing mobiles within the cell. A mobile can communicate with more than one base stations belonging to more than one cells in its proximity. In conventional networks, the decision to service a mobile is taken care by the base stations. As the number of mobiles and load increases, the communication and computation overhead at the base station increases exponentially. Due to limited processing capabilities of the edge base stations in comparison to core network, a significant amount of latency is induced in the network for the service decisions like handoff, uplink power management, bandwidth allocation and QOS provisioning. In this paper we have proposed cross layer architecture for taking service and providing decision to core of the network from the edge of the network. By the use of cross layer based technique base station collects the information of bandwidth from the MAC layer and delay from the physical layer. Combining these two matrices then overall bandwidth is calculated. The proposed system with cross layered architecture we can get less wastage of energy, low latency and better packet delivery ratio and more throughputs even at more nodes. A simulation result suggests that the proposed system is more effective and gives better performance than the present system.
