Software Defined Device to Device Communication Handover- Latest Advancements

Abstract

In recent years, volume of data traffic has increased due to many multimedia applications that are supported by devices such as laptops, smartphone, tablets etc. Multiple users accessed by devices when connected to the internet simultaneously lead to overflow of the data traffic. Many solutions have been introduced to overcome these data traffic problems but the existing radio resources and cellular operators are unable to completely mitigate these problems. Device to Device (D2D) communication in cellular networks is designed to maximize the interference management and resource allocation by off-loading the high volume of data traffic. The current paper throws light on the latest works and developments of D2D communication and its evolution alongside Software Defined Networking (SDN) and emphasizes on the energy efficiency and signaling cost of the SDN based D2D networks.
