# Design of a Technique for Accelerating the WSN Convergence Process
## 8 Conclusions  
At the conclusion of our study on fast routing in the event of a link or node failure, we can state that these techniques have an impact on ensuring the reliability and efficiency of communication networks. Our research efforts focused on testing the AODV routing protocol in the OMNET++ simulation environment and implementing a new add-on module based on RFC 5880 (BFD). This module was able to speed up the detection of network failures through simple \"Hello\" messages, resulting in faster and more efficient recovery of wireless sensor networks.  
Our effort contributes to the development of effective and reliable mechanisms for solving outages, detecting faults, and quickly restoring network operations, which has the potential to increase the performance and reliability of communication infrastructures. This work paves the way for further research efforts and innovations in the field of high-speed routing and network security to better prepare networks to meet demanding challenges and ensure continuous connectivity.

The method proposed by us to speed up the convergence process is suitable for use in risky parts of the network, where it can ensure increased availability and reliability of individual nodes. Its disadvantage is the waste of the energy resources of the devices.  
The future direction of research in the field of FRR will be towards the security of networks and their resistance to attacks, as the growing threat of cyberattacks brings the need to develop techniques that are able to effectively solve network outages caused by attacks but at the same time ensure the preservation of integrated security mechanisms.  
Overall, the future direction of research in the field of FRR and network security will be towards even more reliable, faster, and smarter solutions that will be able to face the demanding challenges of modern communication networks.
