Paper Title
Designing a System for Smart Controlled using AWS

Abstract
Recently, IoT technologies is gaining increasing attention with the improvement of networks. However,the network will be unstable in some scenario. In order to ensure the reliability of system for IoT, we designed a system that can control smart and traditional devices offline. In this paper, we presented the design and implementation of a cloud-based IoT infrastructure in AWS. Then, we show that AWS, MQTT and Greengrass are good for unstable network scenario. Keywords - Greengrass, IoT, Smart scenario, AWS, Offline.
