In Heterogeneous Network (HetNet), reasonable resource allocation has attracted extensive attention. To allocate the resource more effectively, we propose a novel algorithm from the perspective of both time domain and power domain. On the one hand, we propose an adaptive Almost Blank Subframe (ABS) configuration scheme to dynamically match the network resources with the real-time load. On the other...
As traditional wireless cellular networks are facing a rapid growth of traffic demand, future networks may consist of a large number of small cells which are densely deployed. However, networks in dense environment is exposed to strong inter-cell interference problem which is critical to networks capacity. To solve the problem, we use the Graph Coloring Algorithm (GCA) to divide the small cells into...
Recently green communications in Heterogeneous Networks has attracted extensive attention. To improve Energy Efficiency (EE) in the premise of maintaining the throughput, we propose an energy-efficient time-power domain resources allocation algorithm. From the aspect of time domain, we propose an adaptive Almost Blank Subframe (ABS) configuration scheme to provide each sector a proper ABS ratio. From...
In this work, we consider a distributed link-weighted and distance-constrained channel assignment (DLDCA) algorithm for a multi-channel multi-hop mesh network, such as community wireless networks, to maximize its throughput. Efficient channel assignment could greatly reduce interference of each link from its neighboring links and subsequently improve the network throughput. In response to it, we introduce...
In this work, we study a link-weighted and distance-constrained channel assignment problem in multi-channel mesh networks with stationary router nodes, such as community wireless networks. A good channel assignment is given as the one which can minimize interference of each link from its neighboring links and subsequently improve the network throughput. In response to it, we introduce an interference...
A piston production line is built in virtual simulation environment based the existing processes and layout. Its simulation result is shown with figure and graphic. Based on those results, some reconfiguring advices are supplied and also simulated on virtual environment. After reconfiguring the piston production line, many results are obtained by simulation, and it is shown that: the work-piece in...
Wireless multi-hop network is a kind of multi-hop broadband distributed wireless network with high capacity and high transmission rate. One of the major problems of wireless networks is the capacity reduction due to the interference among multiple simultaneous transmissions. In order to effectively minimize the effect of interference, this paper presents a new routing metric called WLQM which considers...
