In mobile ad hoc networks, participant devices need to cooperate with each other to overcome the individual resource constraint. Dynamic service composition is a promising solution for this problem. This paper proposes a novel approach aiming at enabling dynamic service composition in mobile ad hoc networks. Our approach is built on a service overlay, called service forest, which serves as an efficient...
The demand for global mobile communications calls the research and development of the satellite constellation networks. But protocol simulation of satellite networks is hard to realize due to the difficulty of satellite networks modeling. Currently protocol simulation system can't support satellite constellation networks fully. To improve the dependability and availability of the simulation system,...
Now it is prevalent that researchers have to leave their laboratory for another place to continue their missions. Facing unacquainted environment and feeling discomfort, they desire to have the same work environment as they are in lab. To resolve this issue, ReMoVE, a Research Mobile Virtual Environment, was presented to fulfill this desire. The architecture of ReMoVE, which is based on the virtual...
The next generation global mobile communications calls the research and development of the satellite constellation networks. But protocol simulation of satellite networks is hard to realize due to the difficulty of satellite networks modeling. Currently most protocol simulation systems can't support satellite constellation networks fully. To improve the dependability and availability, we propose a...
It is the requirement of the next generation communication systems that devices should provide all existing and future communication services in integral way. After the implementation of 3G technology, smart devices now support text, voice and video communication all in on device. With Wi-Fi technology and low cost Wi-Fi devices available in the market, users can enjoy even free communication services...
In order to screen heterogeneity of sensor hardware and support rapid development of applications in context-awareness, the idea of middleware is widely adopted. In this paper, the middleware is proposed to support the application development of context- awareness under the new-type networks environment represented by wireless sensor networks. It applies the updated service-oriented and light-weight...
Impeded by the bottleneck of the information collection in the information chain, researchers are more and more interested in the development of wireless sensor networks; the applications of wireless sensor networks are growing too. But less attention are paid to wireless sensor networks planning. To resolve deployment challenges, reduce the deployment risk, we propose to build the planning and deployment...
With the actual applications of the wireless sensor networks growing, the challenges of the actual deployment get more and more. To improve deployment efficiency, reduce the deployment cost and evaluate the deployment risk, we propose the planning and deployment platform for wireless sensor networks. In this paper, we investigate the architecture of the planning and deployment platform for wireless...
