In many traditional hierarchical routing protocols proposed for mobile ad hoc networks, each cluster designates a single cluster-head (CH) node to relay inter-cluster traffic. These cluster-head nodes become traffic “hot-spots” and restricting cluster to access through cluster-head nodes can lead to sub-optimal route. To solve these problems, we proposed a novel cluster-based distributed gateways...
With the popularizing of digital TV, Cable TV(CATV) network develops rapidly in the recent years. More large scale resource involved in the CATV network makes demands of the more effective management system. This paper analyses the characteristics of CATV network resources, offers a hierarchical model and gives the architecture, development principles, and implementation of a comprehensive CATV Network...
A robust and efficient level set segmentation method using the energy in a reasonable range of segmentation dependent information (RSDI) is presented. A feature describing edges' illegibility, called the edges' blur descriptor, is first defined. Then it is used to compute RSDI adaptively and approximately. Some methods of segmentation dependent information localization (SDIL) utilizing a window function...
