Identification of Hole Using Packet Forwarding Process Based On Localized Node Movement

The wireless sensor network(WSN), is the monitoring of a specified region of interest(ROI).wireless sensor network is a collection of sensing devices that can communicated wirelessly in each device can sense,process,and talks to its peer.In the proposed system,each and every nodes sending request to the hole manager and those manager receive that all incoming messages based on node movement from one location to the another location.so,its used to reduces time for identifying the hole in network based on sending error messages using packet forwarding algorithm as well as the detection of hole where replaced into the proper nodes due to the movable nodes.based on that algorithm network finds the holes in entire network and remove the holes based on hole healing process.In the existing system,to address the problem of hole detection and hole healing.the distributed hole detection(DHD),is proposed to identify the boundary nodes and discover holes.second,we present a virtual forcesbased hole healing algorithm.but it only detect hole in network centre.although more than one DTN have same packet so DTN memory is wasted.
