RELATED WORK

Healthcare area in recent years has been rapidly integrating technology in the monitoring, diagnosis

and treatment of patients remotely. To improve quality of life of patient and to facilitates tracking of patient

who needs real time data collection. Most studies reviewed point to a chronic disease monitoring in particular

as in which are responsible for the first remote monitoring of vital signs and the second of a telemedical ECG

system of a patient [12].

Other systems such as those proposed are fixed in the IoT bring advantages in terms of perception,

transmission and application of information in the field perspectives of health and medical care. Enabling

smart, an accessible and communication system based on IoT hosting segments such as: medical equipment,

information management control medication of patients, telemedicine, mobile medical care, and personal

health management, among others.

Home automation or Smart Homes (also known as domotic) can be described as introduction of

technology within the home environment to provide convenience, comfort, security and energy efficiency to

its occupants [13]. Adding intelligence to home environment can provide increased quality of life for

the old-people and disabled people who might otherwise need caregivers or institutional care.

There hase been a significant gruth in home automation lastely due to higher affordability and

progression in Smart phones and tablets which permits huge and easy connectivity. With the introduction of

the IoT, the studies and employment of smart homes are getting more popular [6]. Much of the research

attention has been given in academic research laboratories. Several wireless communication technologies that

can support some form of distant data transmission, detecting and control such as Bluetooth, Wi-Fi, RFID,

and cellular networks have been used to insert numerous stages of intelligence in the household [14].

Researches in [13, 14] have intreduced Bluetooth based home automation systems using Smart phones

without the Internet controllability. The appliances are physically connected to a Bluetooth sub-controller

which is then accessed and controlled by the Smart phone utilizing built-in Bluetooth connectivity. However,

due to limited distance of operation (up to 100 m only) the network is incapable to manage with mobility and

can only be controlled within the vicinity. Academics have also tried to provide network interoperability and

distant access to control appliances at the house based on home-gateways. [17] Presented a Wi-Fi using home

control system based on web server which accomplishes the connected home appliances.

A GSM based communication and control for home devices has also been introduced by [18] where

diverse AT commands are transmited to the House Mobile for controlling diverse devices. The disadvantage

of this network is that manipulators are not provided with a graphical user interface and they have to

remember diverse AT commands to control the attached appliances.

The above cited systems have made momentous contributions to the design and improvement of

domotic systems. Though, the current works were generally focused on switching and controlling home

devices or connected appliances rather than distantly monitoring of home environment.

THE PROPOSED SYSTEM: SMIS

This section describes the proposed architecture and design of flexible and low cost controlling and

monitoring system. The architecture is divided into three layers: monitoring area, communication module and

Remote Environment (smartphone, tablet). Remote Environment represents authorized users who can

visualize the sensed data on their Smart phone using sms via GSM. Monitoring district consists of a software

and a hardware interface module as demonstrated in the Figure 1 below.

The diagram of the control system of Figure 1 can be divided into two parts:

a. The top part includes a GSM module, tablets, smart phones, etc.A tablet or smartphone serves as a remote

control via GSM.

b. The lower part includes an intelligent central controller, RF modules, control modules, environmental

modules, data collectors, and so on. The intelligent central controller is a link between the previous and

the next in that it combines the top and the bottom. He is responsible for setting up a WSAN RF433 MHz

(Wirless Sensors & Actors Network) in a studied envirement. These versatile control modules are

responsible for controlling the devices and communicating with the central controller.
