Defective Motes Uncovering and Retrieval for Optimized Network

Two ways exist in the FDN formation. Either all Functional Devices (FDs) can be within a given area or can be spread into multiple areas. There are limitations on FDs with respect to battery level and range of communication. If the FDs are spread across multiple areas then each area should have a FD which can take ownership of communication with respect to other FDs. Like this process is done across all the areas. In legacy system the selection of FDs was done either randomly in each cycle of data transfer or selection of FD is done based on remaining energy for FDs. The method which needs to have good Goodness ratio will have multiple criteria s in place like residual energy, distance with respect to base station. Also the overall performance of the FDN can be improved by identifying the bad FDs whose remaining energy is low and then replacing few of them so that balancing act is there with respect to FDN optimization and cost of maintained. In this paper FDR (faulty FD detection and recovery) method is proposed which triggers at regular intervals in the FDN and then identifies faulty nodes to be recovered. It is then compared with existing LEACH and Modified LEACH method for several parameters.
