Large-scale 3D city building models has now become an indispensable part of digital globe information system. It is a big challenge how to make use of limited computer memory space and rendering ability to draw almost infinite city building models on the earth. In this paper, we focus discussion on how to improve the efficiency of management and rendering of largescale 3D city building models, which...
We consider the problem of centralized multihop scheduling in wireless mesh networks for solutions to realize intelligent transportation systems. A scheduling tree construction strategy is investigated, which could use any predetermined selection metrics, while avoiding primary and secondary interferences to a great extent. Two centralized multihop scheduling algorithms are presented to schedule nodes...
In this paper, we consider the problem of routing and scheduling to form a centralized spatial reuse designing framework for fixed multihop relay wireless access networks. Both minimal hopcount and maximal signal strength strategies to construct a routing tree are investigated. New scheduling algorithm is presented to schedule links on a tree level basis. In contrast with graph coloring, the new method...
