Abstract

The next-generation wireless networks (5G Networks) predict an expantion in the connected device's number and network interfaces with higher transmission capacity, and consequently an exponential increase in the amount of traffic. In this context, solutions that do not overload the wireless communication infrastructure are needed to improve efficiency. This paper presents a cache’s proposal based on interest and interaction between devices in networks with D2D communication, which seeks to settle some of these problems. The proposal is based on cache approaches’ and solutions case studies aimed at improving the network’s use through the efficient use of its resources. It was verified that the proposal presents improvement of 25% when compared to another cache’s approach. From these results we can conclude that the use of this information can be beneficial for 5G networks strategies.

Keywords: 5G Networks, D2D Communication, Cache, Efficiency.
