  Fog Computing architecture for IoT Smart traffic applications 
                                                      Abstract
         Nowadays Internet of Things (IoT) represents a technological revolution 
       able to change the world by connecting physical and virtual objects to the 
       Internet. This technology can offer many advantages, but it still has some 
       limitations such as overused local networks, uncontrolled data loss, etc. All 
       these  limitations  can  be  overcome  by  using  emerging  IoT  architecture 
       which  are  consisting  of  sensor  nodes,  edge  layer  (devices),  fog  layer 
       (gateways) and cloud layer. This paper has proposed a model for smart 
       traffic  applications  which  is  based  on  fog  architecture.  This  fog-based 
       model  architecture  helps  reduce  the  network  load  by  processing  data 
       before  transmission  and  helps  in  reducing  the  energy  consumption  of 
       sensor  nodes  by  reproof  computation  from  sensor  nodes  to  fog  layer 
       (gateways).  The  most  important  advantage  of  this  model  is  that  only 
       processing data are transmitted to the cloud, so data loss is avoiding.

            today the term “Internet of Things” is used to determine advanced 
                connections  of  devices,  systems  and  services,  that  reach  out  from 
                machine to machine-to-machine and overs various protocols, domains 
                and applications.
            Nowadays The Internet of Things developed very quickly and these IoT 
                technologies  enable  the  connection  of  a  large  number  of  users, 
                devices, services and applications on the Internet.
            The  IoT  platform  is  a  software  and  hardware  environment  for  the 
                efficient development of IoT systems. 
            During the development of IoT platform is necessary to consider the 
                necessary  functionalities  elements  such  as  devices,  communication 
                components,  services,  management  of  IoT  platform  functionalities, 
                security and application.

            For development, IoT is used next technologies: network technologies 
                and  protocols,  sensory  networks,  mobile  technologies,  cloud 
                computing and big data. 
            IoT application is  the  layer  of  IoT  architecture  where  users  can  use 
                processed data from the data warehouse on the cloud for one purpose.
            they provide the user interface for interacting and using data from IoT 
                devices, but the same IoT devices can have their user interfaces.
            For developing IoT applications popular languages such as Java, Swift 
                and Node Js are used. 
            IoT is applied in various areas such as agriculture, industry, medical and 
                healthcare, transportation, building and home automation, industrial, 
                energy management, environmental monitoring, living lab, military and

            IoT applications require Edge and Fog computing for reducing overall 
                delay.
            fog and edge layers not only minimize latency data, but also bandwidth 
                consumption of IoT applications. 
            fully-implemented landscape for IoT applications would consist of four 
                layers: IoT Mist computing layer, Edge computing layer, Fog computing 
                layer and Cloud computing layer.
            Mist computing layer or extreme edge is formed by IoT devices that are 
                computation-enabled and can be coopered with each other similar to a 
                mesh network. 
            The edge computing layer enables gateways such as dedicated routers, 
                switches or based stations located close to IoT devices to act as the 
                gateway to the fog or cloud layer. 
            The fog computing layer is an intermediary layer to alleviated edge and 
                cloud limitation.
