Abstract

Cognitive radio is a technology for wireless communication networks that employ the upcoming Dynamic Spectrum Access ( DSA ) . DSA technology allows users who do not have a license called the secondary spectrum users to use the licensed spectrum that primary users while not in use. Application of DSA by secondary users to improve the spectrum utilization efficiency without disrupting or causing interference to the primary user. Later developed into a multi - user cognitive radio or cognitive radio networks use frequency spectrum together with a primary user ( PU ). Methods switch 'off' the user who gives the biggest interference to PU is the best method with the greatest increase in performance, both the capacity and the number of active SU while the combination of methods switch 'off' the user who raised the largest overall interference with the method switches 'off' user given biggest interference to the PU is an alternative method that shows the consistency of performance improvement in the number of potential users over 10 and able to dominate the entire method over another is begun saturation and decreased capacity. Abstracts are made in two languages, English and Bahasa Indonesia. Abstract more about background, purpose, up to, the results of research, and manai research.

Abstract

Abstract A sluice gate is a supporting structure in a dam, reservoir, river, gutter or ditch which functions to regulate the control of water discharge in each flow. With good and controlled irrigation, irrigation systems and waterways from upstream to downstream can be controlled, so that the need for water in agriculture, fisheries, plantations, and industry can be met and relied on properly. The sluice gate functions to control water so that it can prevent flood water in a fast and high flow. The flowing water will lead to the river to the ocean. Therefore the author will design a prototype of an Internet of Things (IoT) based automatic sluice monitoring system. this system requires interrelated components, namely NodeMcu as the control center of the system as well as a wifi module and the relay module as an electrical switch to turn on or off and use the blynk application.
