Fog computing based radio access network in 5G wireless communications

The requirement of 5G also known as fifth generation wireless is for the purpose of facing the huge levels of growth in the data traffic of mobiles and simultaneously reducing consumption of power. A heterogeneous network that has technologies with multiple access along with base stations that are large in number with the aim to increase the capacity and the coverage of the network. Management of spectrum, allocation of bandwidth, channel state information, routing of data, assignment of power transmission as well as management of energy are the basic operations of the network. Designs of allocation with cross-layer resources are utilized to improve the operations of the network. C-RAN or Cloud radio access network is a unit that is centralized and baseband unit or BBU which pools conflicts with signal processing of a large scale and edge catching. To avoid this issue, a cross-layer design based on F-RAN architecture is made use of. This provides communication in a peer to peer style between the end user and the data center. This technique also addresses issues in implementation with higher quality and better services for the users of mobile. The approach of Cross-layer design along with F-RAN has been tested with an NS2 simulator and was found that its performance was better than that of the AODV protocol.
