FAULT TOLERANCE IN WIRELESS SENSOR NETWORKS USING CONSTRAINED DELAUNAY TRIANGULATION

Abstract

Fault tolerance is one of the main issues in Wireless Sensor Networks (WSNs) since it becomes critical in real deployment environment where reliability and reduced inaccessibility times are important. In this paper, we propose a fault–tolerance technique for coverage area of the sensor network that enhances the energy efficiency by reducing the communication, with the help of Constrained Delaunay Triangulation intersect line. Further by applying the above approach, we reduce the energy consumption and congestion in the network. In last, we describe our approach with a case study that our approach is better in fault tolerance and energy saving.
