Abstract. The ubiquitous technology has brought many advantages in the

development in the area of agriculture. The development of u-farm mobile

assistant system has been very interesting research topic in recent time. The

interconnection with heterogeneous objects, sensing of various phenomena and

gathering of large amounts of data are becoming part of our daily routine. In the

field of agriculture, specifically on farming, the advancement in technology also

brought many improvement in the facilities used in farm. This paper develops a

u-farm mobile application architecture which will help the farmers in

monitoring their crops, generate report and statistics which can help the farmers

improve their harvest. The mobile application architecture will maximize the

use of the smart phone from software to hardware.

Keywords: u-farm, smart grid, USN, CBD

1 Introduction

The sensing technology has been drastically adopted in any area of application. It has

been the major component of embedded system, particularly in cyber-physical

system. Nowadays, the application of sensor devices has been widely used. It is seen

to revolutionize many of the farm mobile application; also the wireless technology

has brought many advantages in the development of u-farm system.

Mobile u-farm applications include applications related to agricultural application

area. These mobile applications may be applied to all aspects of our lives. For the

satisfactory information transmission of the mobile u-farm, seamless data transfer

must be supported. U-farm is a network consisting of interconnected devices using

sensors to timely monitor the environmental conditions in the farm. These conditions

can be temperature, pressure, vibration, motion or pollution remote in different

location.

In this paper we designed a u-farm mobile application framework which helps the

farmer managing their resources, monitor their farm environment with the help of the

sensing devices and generate reports and statistics. This paper also includes the

development of mobile gateway which makes it possible for integration for sensor

devices. We have presented here the mobile gateway architecture in which the main

purpose is to receive the sensing data and make a local analysis and generate

keywords and then will be sent to remote server for analysis. This mobile gateway

used Bluetooth technology to send and receive data from the sensor devices [1][2].

2 Background of the Study

Ubiquity means the environment that users can receive the environmental context

regardless of the location and time. As a consequence of the developments of science

and technology and sensing technology is evolving from the previous manual farming

facilities to more improve ubiquitous farm [4].

(u-farm) application. As the quality of the life has been improved, we are more

focusing on the speeding of farm facilities and monitoring in means of ubiquitous

application. Along with the circumstance, the interest of the remote-monitoring of

crops condition has been increasing. The u-farm systems are developing that can

monitor the farm status in a distance in a real time. This system is the service which

can help to monitor the conditions in the farm like for example the water system, the

temperature, the fertilizers and other necessary things in the farm through the

portable-equipment based on wireless communication network. Nowadays, the field

of farming becomes more grew and sophisticated in the used of farming tools. The

purpose of these u-farm technologies is to provide convenient farming service to the

farmers even though they are far away or in travel. They can monitor their farm

without actually visiting on the site. U-farm system can provide efficient monitoring

services through computerized sensing tools and devices. With the development of

new sensing, networking and processing technologies makes farm monitoring easy

and accessible anytime, anywhere. The u-farm application enables a person to receive

services beyond the time and distance that is the motivation in making ubiquitous

farm. Ubiquitous farm using body sensor network technologies in daily live context is

believed to be the next generation of farm technologies [3].

3 U-farm Deployment Challenges

There have been much technological advancement in many field of study but in the

area of agriculture is a little bit slow. This is because we don’t put much interest in

agriculture as it is not so much profitable compared to having a business that earn in

daily basis. Hence, we should not neglect that reality that foods are fundamental needs

in our life. The challenge in developing the u-farm mobile application is the costing of

the needed materials, like sensors devices and the other needed materials.

The USN functions as a centralized network ensuring all the key activities

including processing and storage. When deployed in a physical environment, the

performance of a USN will inevitably deteriorate overtime. The issue of incompatible

protocols is a big barrier to enabling remote access in conventional mobile phones. In

u-farm application, it is very important to design a reliable ubiquitous system since it

is expose to outside environment. The current studies try to develop a mobile sensor

application to assist the farmers in monitoring their plant condition and the

environmental factors.

Farms consist of various elements which are constantly changing state; for

example opening and closing gates, water trough levels, feed levels etc. Monitoring

the status of these elements automatically reduces the workload of a typical farmer, as

well as providing benefits such as real-time monitoring, alerts and statistical analysis.

To provide real-time monitoring, alerts and statistical analysis there is a need to

develop a ubiquitous farm application using mobile devices which can be a big help.

To address this problem, a sensor mobile gateway should be proposed that when

placed in a USN field; enable communication between mobile phones and USN

nodes.

4 Proposed Mobile Framework

This section discusses about the proposed mobile a framework. The conceptual model

and the system components are presented.

4.2 System Components

The components of the system were developed based on CBD concept of software

development. In the figure below, there are three (3) players that can use the system.

Each of this user have the designated function and can access the system according to

the level of access grant they are allowed. The farm owner have the full access of the

system, he can manage the resources, generate and print the inventory reports. The

tenant can access the control for sensors and the monitoring of the alarm systems. The

agriculturist has the access to generate the analysis and reports to do his job as

agriculture analyst. The Figure 2 below is the use case of the system which depicts the

system components.

The first layer is the sensing layer which consists of sensor mobile gateway and

hardware communication. The second layer is the computation layer which consists

of operating system and mobile gateway adaptation layer. The third layer is the

sending layer which is the user interface layer.

It provides the sensed information to a farm field to remote station. It analyzes the

details of the environmental factors information through sensors and received by

mobile gateway and send to the remote server for analysis. It can provide selective

environmental knowledge using the farm expert system.

6 Conclusion

This study proposed a design of u-farm mobile application framework. We have

presented the conceptual model and the system components that comprise the mobile

application. This paper also presents the mobile gateway interface to support the

mobile devices to be a device to receive sensing information from the sensor devices.

It perform environmental (temperature, water level, humidity, plant growth and etc.)

sensing capability. This study aims to make mobile device gateway an integrated

gateway which supports heterogeneous devices. In the propose u-farm system, the

received sensing information will be analyze using smartphone devices which will

generate keywords. The keywords will then be sent to the knowledge expert system

for analysis. This provides the benefits such as real-time monitoring, alerts and

statistical analysis of crop conditions and environmental factors.
