Combined heating and power (CHP) microgrid is conducive to the realization of energy cascade utilization and meeti the users' needs with divers types of energy. With remarkable economic and environmental benefits, CHP microgrid is one of the potential development directions of smart grid. In this paper, a CHP microgrid consists of wind turbines, photovoltaic cells, microturbines, gas-fired boilers,...
The emergence of applications such as VoD system is based on the development of streaming media. The improvement of scheduling algorithms accelerates the transform of streaming media applications from experimental phase to large-scale using. Of all the dynamic scheduling algorithms, the performance of patching algorithm is obviously superior to other dynamic scheduling algorithms. Dynamic scheduling...
A growing number of applications require disseminating information around specific geographical areas within a limited valid time. For example, the store in the mall area expects to publish the time-limited sales promotion to all the potential clients in the nearby area, before the discount activity end. In this paper, we study the problem of deploying infostation for geographical information dissemination...
In the conventional security protection system, more separated data encryption from user identification authentication, and mainly focused on the former but ignore the latter. In order to address this problem, the dynamic and double encryption system based on two-dimensional image is presented, which combined the identification authentication with file encryption. Our approach is that, in the identification...
Nodes localization in mobile sensor networks can be dealt as a problem of mobile object tracking. The particle filters algorithm which is based on Bayesian estimation and Monte Carlo method is an effective tool to deal with these problems. The particle filters algorithm adopts a series of weighted particles to represent the possible position of a mobile object, and then makes use of the present observation...
