Security always comes with a price in terms of performance degradation, which should be carefully quantified. This is especially the case for wireless ad hoc networks (WANETs), which offer communications over a shared wireless channel without any preexisting infrastructure. Forming end-to-end secure paths in such WANETs is more challenging than in conventional networks due to the lack of central authorities,...
The intelligent press forming of sheet metal is a completely new and comprehensive technology that combines control-science, computer science, material science and metal forming theory. Although the technology originated in 1980s from America, it had focused on the spring-back of V-shaped bending. The author expanded the the research field to the axis-symmetric part and non-axis symmetric part and...
Wireless ad hoc networks (WANETs) offer communications over a shared wireless channel without any pre-existing infrastructure. Forming peer-to-peer security associations in self-organized WANETs is more challenging than in conventional networks due to the lack of central authorities. In this paper, we propose a generic model to evaluate the relationship of connectivity, memory size, communication...
