This paper represents a careful study of the security aspects of Java 2 Micro-Edition (J2ME) Connected Limited Device Configuration (CLDC). This Java platform is intended for resource-constrained devices, with the purpose of expanding the range of applications available for these devices, by enabling them to run Java programs. Consequently, malicious code would pose a threat to the security and...

Technologies like Java 2 Micro Edition and Microsoft’s .NET framework allow applications to be developed and deployed across a range of mobile devices without having to significantly change the source code. However, mobile devices have very different interfaces and capabilities and it is not clear whether these generic deployment technologies adversely affect the usability of applications by ig...

Software Product Lines (SPLs) encompass a family of software systems developed from reusable assets. One issue during SPL maintenance is the decision about which mechanism should be used to restructure variabilities aiming at improving the modularity of the SPL artifacts. Due to the great variety of mechanisms (inheritance, configuration files, aspect-oriented programming), selecting the incorr...

Current mobile phones provide GSM cell information and many devices also support GPS or WiFi-based location information. A problem with raw location data is that it does not provide semantic information, which makes it hard to integrate location-awareness into applications. Moreover, to understand what kind of location information is important to users, researchers currently need to perform tim...

The traditionally separate technologies of the Internet and mobile computing have now started to converge, bringing promises for seamless wireless Internet access through portable devices. This article represents a comprehensive review of the main technological, architectural and business issues related to the current state-of-the-art wireless web technologies: WAP, i-mode and J2ME. A brief rev...

The Java Location API for J2ME integrates generic positioning and orientation data with persistent storage of landmark objects. It can be used to develop location based service applications for small mobile devices, and these applications can be tested using simulation environments. Currently the only simulation tools in the public domain are proprietary mobile device simulators that are driven...

In this paper we present a methodology and protocol for establishing a security context between a Mobile Operator’s application server and a GSM/UMTS SIM card. The methodology assumes that the already issued Mobile Station is capable but unprepared. The proposed scheme creates a secure entity within the Mobile Station “Over The Air” (OTA). This secure entity can then be used for subsequent SIM ...

This work presents an approach to designing a software framework for developing multiplayer games: the P2P Game Network Framework, centered in network communications and interaction with the context. This general design assumes a group of devices organized in a P2P network, implying the necessity of tools for selforganization of the group and group synchronization. These tools aim to guarantee ...

This paper describes the prototype for a set of mobile instruments in which java phone technology has been adapted for performing microtonal music. The prototype was developed using widely available mobile phone handsets instead of building new hardware. The paper discusses aspects of j2me development together with limitations of the mobile platform used for the project. Development issues such...

Data mining services play an important role in the field of Communication industry. Data mining is also called knowledge discovery in several database including mobile databases. In this paper, we discuss and analyze the consumptive behavior based on data mining technology. We discuss and analyze different aspects of data mining techniques and their behavior in mobile devices. We also analyze t...
