Peningkatan Efisiensi Penyimpanan dalam Jaringan IoT melalui Metode Cache Replacement LRU (Least Recently Used)

Abstract

The Internet of Things (IoT) is a network of devices that are interconnected and can communicate with each other. Because the devices are connected directly to the Internet, the IoT devices have limited resources to access the data they own. This data can be stored in a variety of locations, such as on the IoT device itself, on a central server, or in the cloud. Storing data on an IoT network itself is a challenge, as data can be large and accessible from any location. Besides, the growing number of users also affects the same thing. This enhancement scans the response speed of the system in dealing with the user's request. When a user wants to access the Internet, of course needs a smart device or gadget that is connected to a web server. Because of the limited storage of both the data storage itself and the storage for cache it is necessary a method to replace the stored data primarily for storing the cache itself. Therefore, the method that can be used to do or replace a stored cache is by cache replacement method with the LRU (Least Recently Used) algorithm. Whatever the purpose of this method is to speed up access and efficiently use cache so that when the web server wants to send the data requested by the user then cache will not be sent and cache has been stored and will be carried out cache substitution method at the location of cache storage. The research has concluded that the Cache Replacement Method can be implemented for the effectiveness of IoT and LRU algorithms in Cache replacement methods to reduce miss hits on cache.
