This paper presents a new framework for building continuous media applications in mobile computing environment. In mobile computing environment, network bandwidth and machine con gurations may be changed dramatically, and mobile applications should be adapted to various operational environments for being executed e ciently. Service proxies make it possible to adapt mobile applications to variou...

For path planning of mobile robot, the traditional Q learning algorithm easy to fall into local optimum, slow convergence etc. issues, this paper proposes a new greedy strategy, multi-target searching of Q learning algorithm. Don't need to create the environment model, the mobile robot from a single-target searching transform into multitarget searching an unknown environment, firstly, by the dy...

The mobile computing world is undergoing major changes both in the capability as well as in the proliferation of mobile devices. While, up to now, mobile malware has played a relatively small role compared to the behemoth of desktop malware, the changing environment is steadily increasing the attractiveness of mobile devices as exploitable resources. The increased usage and connectivity of mobi...

The network management architectures used in practice lack distribution, decentralization and exibility. In addition they have not kept pace with the latest technologies. Some approaches have been proposed to introduce new technologies in the domain. Recently there have been proposals to have a thin client approach to network management. Other suggestions have been to use mobile code for delega...

As Grid technology evolves it is becoming evident that the inclusion of mobile devices in a Grid environment will benefit both the Grid and mobile network communities. Many mobile devices, however, have limits on their computational resources that make it difficult to achieve this goal. The Personal Distributed Environment (PDE) is a new concept in mobile networks which, by constraining the pro...

Mobile worker’s presence and availability at mobile devices can be very crucial in enterprise collaborative environment due to the not-always-on nature of the mobile devices. We identify the key challenges in tracking the presence status of mobile device and user and in the integration of mobile devices with enterprise collaborative environment. We present the design ideas of a Presence-Enabled...
