Introduction
Modified DSR (Distributed System Routing) is a key concept in the field of networking and communication systems. It plays a crucial role in efficiently routing data packets across various nodes in a distributed network. This project aims to analyze the existing DSR system and propose modifications that can enhance its performance and reliability.
Problem Statement
The current DSR system faces several challenges such as high latency, packet loss, and limited scalability. These issues hamper the overall performance of the network and lead to inefficiencies in data routing. Therefore, there is a need to identify these shortcomings and come up with solutions that can mitigate these issues.
Existing System
The existing DSR system relies on a reactive approach to route data packets. When a node needs to send a packet to a destination, it broadcasts a route request packet that traverses the network until it reaches the destination. The destination then sends a route reply packet back to the source node, establishing a path for data transmission.
While this approach is effective in small-scale networks, it proves to be inefficient in larger networks with a higher number of nodes. The increased traffic leads to longer route discovery times and higher chances of packet loss. Additionally, the source node needs to maintain a routing table for all possible destinations, leading to increased memory overhead.
Disadvantages
Some of the key disadvantages of the existing DSR system include:
- High latency in route discovery
- Packet loss due to network congestion
- Limited scalability with a growing number of nodes
- Increased memory overhead for route maintenance
Proposed System
The proposed modified DSR system aims to address the shortcomings of the existing system through several key modifications. One of the key enhancements is the introduction of a proactive route maintenance mechanism that periodically updates routing tables across nodes in the network.
Additionally, a hierarchical routing approach will be implemented to reduce route discovery times and improve the overall efficiency of data transmission. This will involve dividing the network into clusters and assigning cluster heads responsible for routing data within their respective clusters.
Advantages
Some of the advantages of the proposed modified DSR system include:
- Reduced latency in route discovery
- Improved packet delivery rates
- Enhanced scalability for larger networks
- Reduced memory overhead for route maintenance
Features
The modified DSR system will include the following key features:
- Proactive route maintenance mechanism
- Hierarchical routing approach
- Cluster-based routing for improved efficiency
- Dynamic clustering to adapt to network changes
Conclusion
In conclusion, the proposed modifications to the existing DSR system aim to overcome the limitations and challenges faced by the current system. By introducing proactive route maintenance and hierarchical routing approaches, the modified DSR system offers improved performance, scalability, and reliability in data transmission across distributed networks. Further testing and validation of the proposed system will be conducted to assess its effectiveness in real-world scenarios.
