In the paper, a simple equivalent circuit model is built between transmitting coil and receiving coil via coupled magnetic resonance, and the simulation of frequency and efficiency is also supply. Node equations for the resonance coils are built by using the equivalent circuit and the optimum distance is analytically derived for optimum coupling coefficient for high transmission efficiency. The equivalent...
The emerging dense heterogeneous networks comprising different types of small cells enable consumers to employ multiple radio access technologies to communicate. In such a dymica network environment, development of robust and self-adaptive network selection mechanisms is required to satisfy the growing demand on ubiquitous network access. Besides, the energy consumed at wireless interface accounts...
Dense heterogeneous networks are deployed for future wireless communication to meet the explosively increasing traffic demand. However, the network densification leads to a great amount of energy consumption especially the operation energy consumption. In this paper, we consider cooperative Base station (BS) operation in downlink dense heterogeneous networks consisting of one macro BS and several...
Advances in wireless communication techniques enable pervasive and ubiquitous video applications. Among different factors concerned, energy efficiency is one of the most challenging issues in multimedia communication due to huge data traffic. Dynamic bursty interference sourcing from transmission of best effort service can make the Signal-to-Interference-plus-Noise-Ratio (SINR) of video traffic fluctuate...
In this paper, IP mobility management protocols have been analyzed and compared in terms of handover latency and packet loss during handover management. Numerical results show that FHMIPv6 outperforms other protocols in the case of packet loss and handoff latency. Effect of L2 triggering time, packet arrival rate and average queuing delay at access router on handoff latency and packet loss have been...
In order to support process construction in wireless migrating workflow system, this paper presents an approach based on task components for resource-limited executing environment. First, we propose a business process construction model based on the idea that the process logic is separated from the process instances, and then abstract the process generation as a resource-constrained combinatorial...
