Proceedings.Twenty-First Annual Joint Conference…
7 November 2002

We present a novel localized networking protocol that constructs a planar 2.5-spanner of UDG, called the localized Delaunay triangulation, as network topology. Expand

Sweep coverage with mobile sensors

W. Cheng, M. Li, K. Liu, Y. Liu, X. Li, X. Liao
Computer Science
IEEE International Symposium on Parallel and…
14 April 2008

We prove that determining the minimum number of required sensors (min-sensor sweep-coverage problem) is NP-hard, and it cannot be approximated within a factor of 2. Expand

How to crowdsource tasks truthfully without sacrificing utility: Online incentive mechanisms with budget constraint
