End to End Latency incurred in Cooperative Communication System

Abstract

Due to uprising of technology, next generations of cellular communication, such as 5G, are expected to provide enhanced data rate, higher capacity & upgraded performance in contrast to existing cellular standards and generations. For this prospect to turn into genuineness, cooperative communication is proposed for the future generation of mobile communication as an optimization technique. It incorporates cooperation in the system using handy devices such as mobile phones, tablets etc. These devices, that are traditionally single antenna devices or nodes are now allowed to use antennas of the other users in the network, logically making an array of antennas which are connected by a logical mean and offering various gains and performance benefits of spatial diversity to a single antenna user at the lower cost as compare to physical arrangement. However, the network latency and data security are seen as primary hindrances involved in the commercial implementation of cooperative communication systems. In this regard, this article presents comparative analysis of end to end latency in cooperative communication in contrast to conventional approach by considering three different positions of relay.
