tailieunhanh - Tài liệu Discrete-Event Simulation: A First Course

There has been much previous work on node localization and event detection [6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16] , includ- ing foundational work on theoretical lower bounds [17, 18]. Sex- tant differentiates itself from this body of work in several ways. First, it does not assume uniform transmission radii (. a unit disk graph) or symmetric connectivity; instead it extracts geographic constraints from the link layer based on a novel, realistic constraint extraction model that accommodates the large percentage of uni- directional links and non-uniform coverage areas encountered in practice. These constraints lead to non-convex solutions, which are typically much more accurate, though more complex,. | Section Discrete Random Variables Discrete-Event Simulation A First Course 2006 Pearson Ed.
