The document proposes an ARQ (Automatic Repeat Request) technique to localize faults in wireless sensor networks. Existing fault localization methods are inaccurate and slow. The proposed ARQ method more accurately detects fault nodes and does so in less time. It will use network simulation tools to test the method.

2. What is AIDS

3. Need of the Project:
• A deployed sensor network may suffer from many
network-related faults, e.g., malfunctioning or lossy
nodes or links .
• These faults affect the normal operation of the
network, and hence should be detected, localized, and
corrected/ repaired.

4. Existing Method:
• Optimal Binary Identification Procedures.
• Dynamic Packet Fragmentation.
• Optimal Test Sequencing Algorithms.

5. Drawbacks in Existing Method:
• Location of fault node is inaccurate.
• Fault node location identification time is large.

6. Proposed Method:
• Faulty components in a network need to be localized
and repaired to sustain the health of the network.
• In this project, we propose an ARQ technique to
localize faults in wireless sensor networks.

7. Advantages of Proposed Method:
• Location of fault node is Accurate.
• Less faulty node detection time.

8. Tools Used:
• Network Simulator 2.
• VMWARE.
