Attacks upon communication networks have become stealthier and more sophisticated, and hardening communication networks has become necessary to avoid service disruptions. While connectivity of networks can be improved by adding links, there are different strategies for such methods. We implement two link removal algorithms that remove links based on highest link-betweenness and nodal degree. We also...
In this study, we proposed a multi-piecewise thinning description method. Thinning is a preprocessing technology often applied in the fields of binary image processing; it is used to transform thick elements in an image into lines with a single pixel width. Because lines include closed and open lines, an effective description method is required for post-processing procedures. Regarding the proposed...
DP (Dynamic Programming) algorithm based on distance-propagating is a very good approach to real-time collision avoidance in robotic path planning. But the problem with DP is the waste of step number of walking in tracking process. For the A* (A Star) algorithm, there are commonly three heuristic, and usually three ways (4-adjacency, 8-adjacency and 16-adjacency) to get the adjacencies. After The...
The capability to query the topology of spatial regions is fundamental to today's centralized spatial computing systems, like spatial databases and GIS. By contrast, this paper explores decentralized algorithms for computing the topology of spatial regions in wireless sensor networks. The approach generates global topological information about regions, using only the local knowledge of nodes and their...
