II. LITERATURE REVIEW
The smart home consist of the opportunity modernization of the smart learning to improve the smart devices about this part some Literature review were provided Alexandria Al-oisi at 2014 studied the relationship between the Internet of Things and wireless sensor networks from the piles of ACOAP transport network objects. This standard provides compatibility between the network of things and the remote sensing system. On the way to do this, the first step of motivation organized the knowledge of IOT, further how sensors can be linked to collect information taking into account the ultimate goal of smart campus. The work utilized the smart COAP (communication constrained protocol) protocol in implementation (Alexandria, 2014).
Ahmed Abdi in 2018 conducted research on IoT and introduced the concept of smart university. It utilizes technology in designing a campus where some of the campus components to be replaced with the smart devices so as to simplify the work done. Cisco packet tracer was used to design a smart office where staff can control the office using their smart phones. IoT gateways provide the link between the smart office and internet through cloud. The objective of this study was to enrich University in a smart mode and use globalization and to connect all devices to the network and enable sensors to help and control the devices. It also allows the collaboration of sensors with devices in the best manner to provide high quality and technology based infrastructure in the university (Abdi, 2018) (Marian, 2015).
Miluzzo Choudhury and A. T. Campbell in 2010 conducted a questionnaire-based survey on mobile phone sensor. The smartphone has many built-in sensors, which is why it is called the most important sensor today. It has a motion sensor, GPS sensor, light sensor, and magnetism. These things are mainly used in different areas of IOT applications. There are different sensors used to measure temperature, pressure, humidity, medical, and so on smartphones are mainly used to control access and control of smart devices (Nicholas D. Isa Al-Shemsi at in 2018 used the revised version of packet tracer in implementing smart home. This version also provided programming environment for controlling objects. To enable wireless sensor and smart objects, Home Gateway and microcontroller (MCU) were employed. Devices were registered using home gateway and MCU was used to link sensors to device. Even though programming language support was provided by the cisco packet tracer, the researcher used Java Script and Python for implementation. (Al-Shemsi, 2018).
Yin Jie et al in 2013 introduced the idea of smart home with IOT. They introduced architecture for the system, in which many applications can be integrated through its interface. RFID tags are exploited to ease the agent communication with the devices. The main issues to be resolved related to smart home is also included in this research (Jie, Pie, Jun, Yun, & Wei, 2013). Jetendra Joshi et al proposed an IOT based smart home which can control, monitor and access multiple devices from anywhere and anytime. They utilized Raspberry Pi and web server. To monitor home appliances, Raspberry Pi and Arduino was incorporated with Nrf modules. The readings are send to web server and it is monitored to give alarms under the influence of threats (Jetendra , et al., 2017) III. METHODOLOGY The idea of smart is very catchy and review on similar researches was conducted to understand its concepts and its architecture. As implemented by majority of researchers, cisco packet tracer was used for implementing smart home. The newly released cisco version was used as it supports home security features as well as provides programming environment besides networking features. The different programming languages supported are visual basic, java scripts, and python. Smartphone and home gateway are used to control the devices such as smart window, smart fan, smart garbage and sensor. The smart devices are connected to the IOT home gateway ports and smart phone is used to communicate with the smart devices.

IV. SAFE HOME DEVELOPMENT
Home gateway has four Ethernet ports and wireless access point configured with the "Home Gateway" service set identifier (SSID). All the devices are connected to gateway using config menu in each device, the name of the gateway has to entered. This can be repeated to all sets of devices that has to be controlled in a home gateway. Ip config menu displays the lidt of devices connected to the home gateway. The smart phone is used to control all the devices.
The cisco packet tracer interface provides inbuilt devices to be added in the network. The first step is to select home gateway device from the network devices. To authenticate and validate the wireless connection, we also can configure home gateway with WEP/WPA-PSK /WPA2 protocols. The second step in simulating a smart home is to connect devices to the home gateway. In this work, six wireless devices were coupled with the home gateway. The devices configured included fan, webcam, door, air condition, garage and motion detector. Figure 2 shows the smart objects connected in our system which included only wireless devices. In order to connect an object, the home object icon has to be selected from the device-type selection box. For example let us consider connecting AC to the home gateway. Select AC icon to the workspace and click it to open various settings of the device. In config tab, name of the device can be updated with the name you need to be displayed. Wireless0 has to be selected to enter SSID of home gateway. This to indicate that the device connected to the home gateway and connected to network wireless. The default gateway is 192.168.25.1. Fig. 3 shows the settings when AC is clicked which has advanced options.
There is another option called advanced at the bottom which gives additional menus. Here in I/O config tab, the network adapter setting has to be set to PT-IOT-NW-1W.  These steps are repeated to add all the objects such as door, fan, motion detector, webcam and garage door. The user will control all devices by the smartphone. Fig.5 shows the features and settings specification of AC such as the name of the port, link, IP address, IPV6 address and the IP of the gateway after connecting to home gateway.

Fig. 5: AC specification
The next step is to connect the smart phone to the home gateway. Select the device type from the end devices selection box. When the smartphone icon is clicked, the configuration window appears. The SSID from Wireless0 has to be updated with home gateway instead of default and it leads to automated IP address generation for the smartphone.

ISSN: 2278-0181 http://www.ijert.org The next step is to add rules and conditions for the smart objects to give notifications or alarm. In order to do this, from smartphone select the desktop tab and click IoT monitor. Fig. 7 shows the window that appears.   Different conditions and rules are programmed based on the smart object connected to home gateway. These steps have to be repeated for all objects.
