SENSOR DEPLOYMENT ALGORITHM FOR HOLE DETECTION AND HEALING BY USING ENERGY BASED LOCAL HEALING
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 7
Abstract
A wireless sensor network (WSN) are small sensors with limited computational and communication power. Each of which is small, lightweight and portable.They are very vulnerable to various type of failures.Sensors are deployed with power source like battery,these batteries are limited energy capacity this may leads to formation of hole in WSN, These types of failures causes the formation of holes in a WSN. One of the main service of WSN is the monitoring a special region of interest(RoI). The RoI continuity is very important to cover whole RoI continuity, there by entire network. So the holes inside these RoI cause breaks in communication. The Localized Movement Assisted Sensor Deployment Algorithm For Hole Detection and Healing (HEAL) is an efficient and effective method for this hole detection and healing. The key elements that ensure coverage for WSNs are determining the boundary of ROI, detecting coverage holes and estimating their characteristics, determining the best target locations to relocate mobile nodes to repair holes, and dispatching mobile nodes to the target location while minimizing the moving and messaging cost.
