Hole Detection and Hole Healing in a Wireless Sensor Network using LeDiR Methodology


Objective: To monitor and control the total area of a Wireless Sensor Network (WSN) without any coverage holes that impair the sensor node functionalities. Methodology: We propose an exhaustive arrangement, which operates in two phases, hole detection and hole healing. We design our system based on Least-Disruptive topology Repair (LeDiR) algorithm. LeDiR scheme enhances the conventional and the extant route discovery techniques in the network, easing the tasks of hole detection and hole healing. Finding/Improvements: We implement our system in NS-2. Our proposed system implements LeDiR, effectively controls the WSN of coverage holes and successful in implementing hole detection and hole healing. We also demonstrate that our scheme is successful in overcoming both the coverage holes and routing holes.
