A calculation method based on the partial capacitance is proposed to analyze the voltage-dependence capacitance system of IGBT(Insulated Gate Bipolar Transistor). The capacitance system of IGBT is modeled with semiconductor junction capacitors and MOS(Metal-Oxide-Semiconductor) capacitors, and each capacitance is obtained by solving the junction voltage under the external bias voltages. At last, the...
Wireless community networks (WCNs) have emerged as a cost-effective ubiquitous broadband connectivity solution, offering a wide range of services in a given geographical area. QoS-aware multicast over WCNs is among the most challenging issues and has attracted a lot of attention in recent times. The existing multicast schemes in WCNs suffer in terms of several key performance metrics, such as, latency,...
In Wireless Mesh Networks (WMNs), supporting Quality of Service (QoS) to enable a rich portfolio of applications/real-time multimedia applications is foreseen to be vital for the success of next generation networking technologies. However, today's cutting edge standards are not perfectly equipped to cater to this task. These standards come with an inherent complexity and suffer from innate problems...
Wireless Mesh Networking (WMN) emerges as a new technology to reshape the broadband industry towards a more efficient and cost effective connectivity. The WMN has been the ideal technology for the next generation wireless community networks that offers efficient digital engagements and an ideal platform for promoting social partnerships over both urban and rural communities. This is essential for...
Wireless Mesh Network (WMN) has been considered as a key emerging technology to construct next generation wireless communication networks. It combines the advantages of both mobile ad-hoc network (MANET) and traditional fixed network, attracting significant industrial and academic attentions. In WMN, the load balancing becomes a hot topic in enhancing the QoS provision as a load balanced WMN exhibits...
As a daily transport, Mass Transit Railway (MTR) is playing an increasingly important role in our life. By comparing the MTR systems in different countries, we summarize their advantages and disadvantages, and then choose the best design to make sure that people may escape from the subway in emergency situations.
Wireless mesh networks have been attracting significant attention due to its promising technology. It is becoming a major avenue for the fourth generation of wireless mobility. Communication in large-scale wireless networks can create bottlenecks for scalable implementations of computationally intensive applications. A class of crucially important communication patterns that have already received...
