Abstract. In this paper, we provide the customized user interface layout which is requested by user’s mobile devices through ubiquitous sensor network. The system doesn’t have a single server but each server is configured as a cloud server based on Hadoop system, which processes data with a distributed processing to provide the customized user interface layout. Based on method of HDFS storage, it stores each data with a distributed processing in DataNode through NameNode Server. DataNode back up data whenever there is a change. Or something is wrong; which resolves any problem to provide seamless data to user. If user requests interface layout through mobile device, related searched XML content is sent to user through ubiquitous sensor network. Also the interface provides different layouts for the elder and people with disabilities by sensing mobile device. The interface layout can be applied easily in various environments because it doesn’t require any special environment setting in ubiquitous sensor network environment.

1 Introduction
As there is a rapid changed IT in mobile environment, today smartphones support various apps with different services. The existing feature phone is to have as a phone, but the smartphone provides various services [1]. It is usually provided for the home users. There is no interface layout for elder and people with disabilities. In this paper, we provide the customized user interface layout which is requested by user’s mobile devices through ubiquitous sensor network. The customization of the interface is proposed which will provide smartphone users with their own customized interface as per there choice it also provides layout interface to the elderly and people with disabilities. The system uses apache hadoop based cloud server for efficient storage as well as for accurate and quick access anytime, anywhere.
2 Related Research
Recently, smartphone penetration as per Ericsson statistics [4], approximately 25 to 30 percent people of worldwide use the smartphones and the services they provide and by the end of this year, forecast of more 19 billion people will be using the smartphone which will increase the penetration rate immensely. Considering it there is customization provided for the user were they can install the various apps, skins which can change their smartphone functionality as they want[2][5].
3 Cloud-based Distribute Processing of User-Customized Mobile
Interface
The existing feature phones and smart mobile devices by using various apps interface can be able to change to a suitable layout. Among them, the soft keyboard layout is a smart phone application for system which provides extra interfaces that can change the appearance and layout of the skin. Many people use a variety of skins as they can be offered to provide some of the layout because it provides more extended available layouts, Use of additional functionalities or the direction keys, numbers or special symbols for faster key inputs is possible which provides flamboyant user interface. It also has a separate layout, that is easier to write a letter or document which helps a lot in fig. 1.
Fig. 1. Any soft keyboard layouts
Soft keyboard changes the layout of the system default keyboard layout which is changed base on applications. The application is launched for giving more functionalities than the system default keyboards, a lot of people are using a typical soft-keyboard layout changes over the system default keyboard. Also, many other soft keyboard layouts provide multi-language support functions so the users are able to access their native keyboard layout.
3.1 Hadoop based system Architecture
Hadoop is to handle large amounts of data, which was created by Google for distributed systems. In addition, it is available as open source because it can be used by anyone without any separate license required. Configuration of the system to Hadoop cluster, is shown fig. 2, which shows that the multiple server computers that can connect with each other. Hadoop is used for two big reasons, first, the HDFS (Hadoop Distributed File System) depending on the type of storage system structure
data can be systematically managed having information about the layout of the interface repository, which is linked to each user interface having information about their relationship and mapping is filled with the data stored.
Fig. 2. Hadoop based system architecture
The NameNode server has information in the form of metadata. The actual data is stored in the DataNode. That is the physical data on the server can be managed by different DataNode, by sharing the data for each server. The HDFS Hadoop-based nodes, copy the backup files because if an error occurs, it will operate normally as it can create multiple copy DataNode. In this paper, we have managed to create two DataNodes. Hadoop system uses the Map/Reduce style programming model. This approach produces users via the Web interface to Save Key and Value information for the faster data processing could be possible. So system uses Hadoop-based structure because there is a wide variety of people will be requesting the data at the same time, or if the users want to create and design their layouts the can do with seamless and effective way with no time.
3.2 System functionality and structure in cluster
Fig. 3. Functionality and structure of system in cluster
In the cluster, all nodes are assumed to sense and control their transmission data. We also assume that a member node is part of the cluster and shares the clustering tasks. The nodes have to transmit layout data toward a remote mobile device through a Cluster Header in ubiquitous sensor network. The mapping management server is selected by the user interface layout, which will manage their index. The user interface uses the authoring Toolkit, for choosing the layout that user want to use in the smartphone as their interface. Users can select on or more layouts as per their choice. The management server uses the information for the mapping process. When
requested, user interface layout the mapping information is based on actual data, the index can be found quickly. Provides an overview of the representation of the actual user data and identify their server user ID, password, and email information when the request's IP information through ubiquitous sensor network. Interfaces are identified interface ID and interface layout management server configures variety of interface layouts created by users through ubiquitous sensor network. The server uses the username and password for log that helps in user identification and interface selection. The server has the user-entered login information which is checked for valid authentication. User can customize the interface layout, smart search, mobile search, allowing you to use one by applying the data to Xml file format enables you to provide information in the form of an Xml file helps in data retrieval that will be send over through ubiquitous sensor network to the user's smartphone. User's mobile device analyzes the retrieved Xml file and allows using the interface layout.
4 Interface Layout on Mobile Device
Fig.4 shows the actual interface which is provided to mobile device through ubiquitous sensor network. The user ID and password, as shown in the illustration on the left enter the login ID and password, if you are not, a registered user it will provide default layout. If you are registered user the illustration on the right is selected by the user interface layout and if you look at the top of the screen user can choose different layouts. The user can also select multiple layouts for his continence and choice. In addition, the interface layout can change in real time. Usually one layout can be applied at time for user to interact with the system after sensing device in cluster.

5 Conclusion
The user can access the interface layouts any time any were only with basic ubiquitous sensor network access conditions. We provide the customized user interface layout which is requested by user’s mobile devices through ubiquitous sensor network. The system is configured as a cloud server based on Hadoop system, which processes data with a distributed processing to provide the customized user interface layout. If user requests interface layout through mobile device, related searched XML content is sent to user through ubiquitous sensor network. Also the
interface provides different layouts for the elder and people with disabilities by sensing mobile device.
