(Inderscience Enterprises Ltd, 2019-04-01)A set of wireless sensors is called a barrier cover if they can monitor the boundary of an area so that an intruder cannot enter the area without being found by any sensor. The quality of a barrier cover is the shortest ...
(Operations Research Society of China, 2018-12-17)This article is an introduction to recent development of optimization theory on set functions, the nonsubmodular optimization, which contains two interesting results, DS (difference of submodular) functions decomposition ...
(Inderscience Enterprises Ltd., 2019-03-24)In some applications using visual sensor networks (VSNs), the facing directions of targets are bounded. Therefore existing full-view coverage (all the facing directions of a target constitutes a disk) is not necessary. We ...
Barrier Coverage plays a vital role in wireless sensor networks. Research on barrier coverage has mainly focused on the lifetime maximization and the critical conditions to achieve k-Barrier Coverage under various sensing ...
In many fault-detection problems, we want to identify defective items from a set of n items using the minimum number of tests. Group testing is a scenario in which each test is on a subset of items and determines whether ...
