Abstract

Focused coverage is defined as the coverage of a wireless sensor network surrounding a point of interest (POI), and is measured by coverage radius, i.e., minimum distance from POI to uncovered areas. Sensor self-deployment algorithm GRG is designed for autonomous focused coverage formation. It however does not always produce optimal (i.e., maximized) coverage radius. In this paper, we propose optimized GRG, referred to as OGRG, for guaranteed coverage radius maximization, and evaluate its performance in comparison with GRG.
