The wireless network evolution has allowed that the handset technology provides a broad and new set of applications to their users. Several of these applications require DBMS solutions that support their operations. Note, however, that these solutions must respect the limitations of the mobile platform, such as smaller memory capacity and lower processing power. This paper discusses our experience...
The development in mobile devices and wireless technologies opens up unlimited choices of mobile services such as mobile commerce. These advances make access services available and convenient everywhere at any time. Since mobile users usually move, accessing services becomes unavailable especially in some locations that are not covered by their home networks. Therefore, it becomes necessary to roam...
In the area of mobile ad hoc and sensor networks, simulation became the evaluation method of choice. Due to the high number of variables - including transmission range, number of nodes, simulation area, mobility pattern-simulation settings vary largely from work to work, depending on the application scenario focused. The results for two simulations with identical setting, but different mobility models,...
Mobile phones and related gadgets in networks are on the spot to deliver sufficient performance for rich multimedia applications and communication. In this report we introduce a video conferencing software, which seamlessly integrates mobile with stationary users into fully distributed multi-party conversations. Innovations related to this work are twofold. At first we report on a highly optimized...
