Comparison between Existing and Proposed Method for Coverage Hole Detection and Recovery in WSN
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 10
Abstract
A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations. Several problems occur in the WSN. They decreases efficiency of WSN. The coverage problem is one of the fundamental issue in WSN. In the paper, we propose an effective approach for coverage holes detection. The network is dividing into square shape zones .Every zone is the combination of several sensor nodes. Also patching nodes based algorithm is applied for the removal of holes. Simulation demonstrates that our algorithm can detect and recover coverage hole and guarantee full coverage with simplified manner.
