Design and Implement Privet Chatting Over Bluetooth for Wide Area

The mobile applications have become one of the important applications in human life, and it was widely used during the last ten years. Mobile devices can be used to do various tasks, such as browsing the internet, sending or receiving emails, and performing other tasks. Bluetooth technology is considered as one of the important specifications that were added to mobile phones during the current century where the user can use it for data and image transmission and others. One of the important applications of Bluetooth, which appeared in the last years, is the conversation via Bluetooth where users can hold short conversations using this technique. One of the most important benefits of Bluetooth technology is that it's free to send and receive messages. While the disadvantages of this application is that it is short-term, since users must be within the scope of the Bluetooth service which is (7 - 9 meters) to be able to send messages and use it. In this paper, we will design and implement a private conversation via Bluetooth software which has the ability to work within biggest scopeby taking advantage of the properties of the (Scatternet). Each user of the application can be a crossroads for the other users. In other words, if there is, for example, users (a) and (b) 7 meters away from each other, and a third user (c) appeared within 12 meters of the first user (a). In this case, the third user (c) can be connected to the first user through the user (b). In other words, the second user (b) would be an intermediary between the first user (a) and the third user (c). So, we have been solved the distance limit problem for using the Bluetooth application. In addition, the users are now able to chat as a group (not just peer-to-peer) in a private room with a wide range using the piconet and scatternet characteristics. Netbeans 5.5, Java 2 Micro Edition (J2ME), Bluetooth API (JSR-82), Nokia Pc Suites are the tools and technologies that have been used through building this application.

Text Hiding in Mobile Phone Simple Message Service Using Fonts

Problem statement: Hiding secret information in an ordinary mobile phone Simple Message Service (SMS). Approach: In mobile phones, there are two default types of fonts, System and Proportional fonts, which have similar figures to human vision and cannot recognized by human eye. The suggested method hides the information (0,1) in cover SMS message by changing the fonts of each character by one of those two fonts (0 represented by System font and 1 represented by Proportional fonts). After embedding secret information in cover message, the Stego message will look like an ordinary message but each character draw in one of these similarity fonts. Finally, at extract site, it must analyze each character font to retrieve secret information. This study has been implemented by J2ME (Java 2 Micro Edition) programming language to works in mobile (cellular) phones. Results: By using two similarity fonts, we can hide one bit in one character of mobile phone message. Conclusion: Good steganography depends on the human behavior and way of thinking. The most successful hiding method is the uncommon one. Although the proposed method is simple but it is unthinkable one and needs knowledge and experience to be discovered.

Practical design and implementation of recognition assisted dynamic surveillance system

Open Service Gateway Initiative (OSGi) and Open-source Computer Vision (OpenCV) are widely used for developing applications. OSGi is constructed to provide a service platform with high application interoperability while OpenCV is used to provide many application programming interfaces (APIs) about image processing. In this paper, we design a recognition assisted surveillance system based on OSGi and OpenCV platforms. The system features dynamic monitoring by a camera carried by a robot and a Java 2 Micro-Edition (J2ME) viewer on a mobile phone. With the assistance of image recognition techniques, the captured frames are adaptively reproduced for handheld phones in a limited bandwidth environment. The proposed adaptive pause time control mechanism can efficiently improve the synchronization relationship between captured and viewed frames across heterogeneous networks. The evaluation results show that the proposed scheme can save power for the moveable camera and have a shorter time delay between the captured and viewed frames.

Design and development of a mobile peer-to-peer social networking application

The proliferation of wireless and mobile devices such as personal digital assistants and mobile phones has created a large demand for mobile software applications such as social networking software. In addition, the realization and widespread usage of peer-to-peer (P2P) networking have drastically increased the number of applications utilizing these technologies. The convergence of mobile and P2P networking have generated increasing interest in the mobile peer-to-peer (MP2P) community. In this paper, we describe the design and development of a mobile social software (MoSoSo) based on a P2P network architecture using Juxtapose (JXTA) and Juxtapose for Java MicroEdition (JXME). The MoSoSo application allows users to discover, communicate and share resources with one another. We present three facets of designing the MoSoSo: object-oriented software design, network infrastructure design, and user-interface design. The software has been fully implemented and tested on a variety of mobile devices for use in a campus setting. By studying the design and implementation of the MoSoSo, we hope to benefit the entire mobile application development community by providing common models and insights into developing MP2P software.

Integrating Multiplexing Facilities in the Set of JRMP Subprotocols

With the process of adaptation and redefinition of Java Remote Method Invocation for J2ME (Java 2, Micro Edition) environments, a reduced version of the Remote Method Invocation (RMI) came up. In this reduced version, called RMIOP, some heavy features such as multiplexing facility or its capacity to go through firewalls offered by the wire protocol, called Java Remote Method Protocol (JRMP), have been eliminated. In the present article it is explored how the recovery of the multiplexing facilities of JRMP, rejected during the RMIOP definition, can be carried out maintaining the J2ME idiosyncrasy. The article begins showing how to extend the triad of subprotocols already defined (SingleOpProtocol, StreamProtocol and MultiplexProtocol) with a new one (MultiplexConnnectionLessProtocol) equipped with special facilities to multiplex connections. It gives support for fast and light connection connectionless virtual connections generation and recycling. The paper ends with an empirical evaluation of the proposed subprotocols together with the already existing ones, in terms of end-to-end response time and the size of the frames transmitted through the network, showing the goodness of the protocols.

Compacting SQL queries for saving resources in mobile ad hoc and sensor networks

This paper presents an SQL query compaction scheme that makes accessing data in mobile ad hoc networks and in wireless sensor networks more efficient. The proposed scheme exploits the SQL syntax and generates a light-weight binary representation that significantly shrinks the size of the queries. Its performance was evaluated after being implemented using the Java 2 Micro Edition (J2ME) platform and deployed on a Sony Ericsson P800 mobile phone. The considered test queries were a representative sample applicable to the SQL syntax of the TinyDB sensor network database. Results show an achieved compaction ratio that is less than 1.6 bits per byte or equivalently greater than 80%, which greatly outperforms the Huffman coding algorithm.

A novel implementation of signature, encryption and authentication (SEA) protocol on mobile patient monitoring devices

Mobile patient monitoring devices are becoming an integral part of healthcare industry and these devices will eventually become the method of choice for accessing and implementing health checks for patients located in remote areas. The thrust behind this research work was to investigate how a complete security strategy, comprising of digital signatures, encryption and authorisation on the mobile healthcare devices could be implemented without compromising overall system performance. Java 2, Micro Edition (J2ME) platform has been used to implement the Signature, Encryption and Authentication (SEA) protocol based on Elliptic Curve Cryptography (ECC). The work presented highlights a practical, secure and effective prototype for interactive monitoring of remote patients. The proposed facilities could improve the quality of care and doctor-patient communications; prevent misuse of healthcare data and consequential expenses to the healthcare industry in an efficient user friendly way that does not significantly affect the device performance.

Location API 2.0 for J2ME – A new standard in location for Java-enabled mobile phones

Key aspects in realizing the maximum potential of advanced Location-Based Services (LBS) are the standardization and cross-platform availability of an Application Programming Interface (API) for mobile phones that allows access to real-time location information. To shorten the development time of advanced LBS, such an API should also provide essential features such as map user interfaces, geocoding, and navigation to be used as building blocks in the context of larger mobile applications. Using these available services, application developers can focus on building innovative location-aware applications rather than re-creating existing services. This article’s main goals are to emphasize the importance of such an API and to describe the Location API for Java 2 Micro Edition (J2ME). This description includes the main features of the current “JSR179-Location API v1.0” as well as the significant enhancements and new services included in the development of “JSR293-Location API v2.0.” These new features, illustrated using coding examples, will help software developers create next-generation location-aware J2ME applications.

An Open and Reconfigurable Wireless Sensor Network for Pervasive Health Monitoring

Sensor networks constitute the backbone for the construction of personalized monitoring systems. Up to now, several sensor networks have been proposed for diverse pervasive healthcare applications, which are however characterized by a significant lack of open architectures, resulting in closed, non-interoperable and difficult to extend solutions. In this context, we propose an open and reconfigurable wireless sensor network (WSN) for pervasive health monitoring, with particular emphasis in its easy extension with additional sensors and functionality by incorporating embedded intelligence mechanisms. We consider a generic WSN architecture comprised of diverse sensor nodes (with communication and processing capabilities) and a mobile base unit (MBU) operating as the gateway between the sensors and the medical personnel, formulating this way a body area network (BAN). The primary focus of this work is on the intra-BAN data communication issues, adopting SensorML as the data representation mean, including the encoding of the monitoring patterns and the functionality of the sensor network. In our prototype implementation two sensor nodes are emulated; one for heart rate monitoring and the other for blood glucose observations, while the MBU corresponds to a personal digital assistant (PDA) device. Java 2 Micro Edition (J2ME) is used to implement both the sensor nodes and the MBU components. Intra-BAN wireless communication relies on the Blue-tooth protocol. Via an adaptive user interface in the MBU, health professionals may specify the monitoring parameters of the WSN and define the monitoring patterns of interest in terms of rules. This work constitutes an essential step towards the construction of open, extensible, inter-operable and intelligent WSNs for pervasive health monitoring.

Embedded file manager for mobile devices design and implementation

In this paper a Embedded File Manager for Mobile Devices (EFMMD) implementation based on RMS (Record Management System) of J2ME (Java 2 Micro Edition) is presented. EFMMD is focused on CLDC-MIDP (Connected Limited Device Configuration- Mobile Information Device Profile) application developers for PDA (Personal Digital Assistant) devices. RMS stores data using record collections called recordstores. Each recordstore is composed by a variable size array of bytes and a unique sequential identifier called recordId. Despite of perform basic management operations, it is not possible to do it as in the relational model. EFMMD implements a set of relational model characteristics through four basic classes: Database, Table, Tuple and DatabaseException, each one have methods that enable to model data structures and their behavior, giving the users the capability of data management as in a traditional DBMS (DataBase Management System).

Design and implementation of a smart system for personalization and accurate selection of mobile services

Wireless mobile services are computing applications that run on handheld wireless devices. Such applications must work within the daunting constraints of the devices, which include memory, processing power, input capabilities, and size of display. It is therefore important that mobile services take into account the user’s context, optimize resource usage, and minimize input effort imposed on the user. In this paper, we present the design and implementation of a smart agent-enabled system for personalizing wireless mobile services and advertisements for Java 2 Micro Edition (J2ME) or Java ME, and Wireless Application Protocol (WAP) enabled devices. We use software agents for context filtering because such autonomous software entities have characteristics that can benefit mobile devices and the wireless environment, and the Composite Capability/Preference Profiles (CC/PP) standard for defining profiles for user preferences and device capabilities. The system incorporates the use of artificial neural networks to adaptively and iteratively learn to select the best available service based on contextual information. The system is evaluated using practical operating scenarios, as well as empirical data and results show an 87% success rate in the selection of the best available service.
