Optimized 3d deployment of wireless sensors network in consideration of the characteristics of the environment

Abstract

Wireless sensor networks are deployed to monitor physical phenomena. The accuracy of the information collected depends on the position of sensor nodes. These positions must meet the application requirements in terms of coverage and connectivity, which therefore requires the use of deployment algorithms. a Good deployment needs also to adapt its operation and save more energy and resources when temperature decreases. This thesis focuses on the deployment of wireless sensor nodes to monitor 3D areas and study the global effect of temperature as the major factor. We integrated two models the first one is to save energy by putting some nodes in hibernate mode as in the SO (Stop-Operate) algorithm, and the second one is Delaunay triangulation algorithm to create communication links.
