Survey on Cache Schemes in Heterogeneous Networks using 5G Internet of Things

Abstract

The 5th Generation Internet of Things is necessary to cope up with the increasing demands of the data with the time. The model of communication demands higher data rates, low latency in the network, efficient power utilization, and reliable transfer of data. To enhance the productivity of the system and to avoid the delays, the cache has played a significant part in the advancement of the 5G-IOT model. The 5G-IOT caching scheme helps in reducing the delays that were caused when there was no cache in the system. Currently, in 5G-IOT, there are caches on each base station, which reduces the delay and enhances the efficiency of the system. Moreover, energy is a great concern in the wireless system. The wireless nodes have limited energy so that it should be consumed in a well-organized and efficient way to achieve maximum effort from them. There are many caching schemes according to the type of network in 5G-IOT systems. There are a lot of methods of caching which takes into account the concern and issue of energy consumption. There are different types of models 5G-IOT caching, one of these is related to heterogeneous systems. Caching in heterogeneous systems using 5G-IOT is explained in this paper.
