Engineering education is one of the classic education model in the worldwide, and which come up from Massachusetts Institute of Technology. Been extensively studied and took a good application. It has been placed in production process of the product or system. Basically it depends technology and focus on practical. Based on the CDIO engineering education theory we studied the issue of Chinese vocational...
The large-scale integration of Renewable Energy Sources (RES) generation, such as wind and solar power, is very helpful for reducing emissions of green-house gases. However, this is at the cost of demanding more reserve capacity of different response time, especially that of the spinning reserve, due to various kinds of uncertainty introduced by the energy sources. A brief introduction of the essential...
Recently, opportunistic routing has been proposed to take good advantage of broadcast nature and spatial diversity to achieve high throughput, despite highly unpredictable and lossy wireless links in multi-hop wireless networks. Most previous works provide heuristic solutions to select as many candidates, and don't take inter-candidate delivery probability into account, which might suffer acknowledgement...
Considering a wireless sensor network with optimal mobile sink track along which data are transmitted to the nodes, a fraction of nodes in the area of interest generate data packets and send them to the sink. Usually the single path routing is adopted in such scenarios which may cause unnecessary transmissions. We address the problem of how to collect these packets efficiently by using network coding...
Coexistence of heterogeneous wireless networks (HWNs) to provide ubiquitous service is an inevitable trend. Vertical Handoffs (VHOs) are crucial requirements for convergence of different access technologies. In this paper, a utility-based VHO decision algorithm is proposed. A profit function is used to calculate the profits gained from a VHO and to select the target network accordingly. Signaling...
The integration cellular networks, wireless local area networks (WLANs), and the new paradigm of mobile ad hoc networks (MANETs) is the trend for next generation mobile networks. And the multi-hop routing mechanism is an open and challenge issue in this area. In this paper, a multi-hop routing mechanism with fuzzy estimation of links for heterogeneous wireless networks (HWNs) is proposed. The mechanism...
Although wireless sensor networks (WSN) have been an active field of research for the last so many years, service discovery within WSN has not been considered much by the research community. Service discovery in wireless sensor networks particularly in the context of future ubiquitous computing plays an important role and its significance cannot be underestimated. In this paper, we present a study...
