Evaluation of the performance of AODV routing protocol in mobile ad hoc networks.

Performance Evaluation of AODV Routing Protocol in MANETs

Introduction

Mobile Ad hoc Networks (MANETs) are wireless networks that do not rely on a fixed infrastructure. In MANETs, nodes communicate with each other directly or through other nodes to send data over the network. One of the key components of MANETs is the routing protocol, which determines how data packets are forwarded from the source to the destination. Ad hoc On-Demand Distance Vector (AODV) is a popular routing protocol used in MANETs due to its efficient on-demand routing mechanism.

Problem Statement

While AODV is widely used in MANETs, there are performance issues that need to be addressed. The main problem with AODV is its high overhead and latency, which can result in routing delays and lower network performance. In addition, AODV may not always find the most optimal route, leading to suboptimal performance in terms of packet delivery ratio and end-to-end delay.

Existing System

The existing system uses AODV routing protocol to establish routes in MANETs. AODV works by sending route request (RREQ) packets to discover a route to the destination node. Once a route is established, data packets are forwarded along this route using route reply (RREP) packets. However, the drawback of AODV is its reactive nature, which can lead to longer route discovery time and higher overhead.

Disadvantages

– High overhead: AODV generates a large number of control packets, leading to increased network traffic and overhead.
– Latency: The reactive nature of AODV can result in longer route discovery time and increased end-to-end delay.
– Suboptimal routing: AODV may not always find the most optimal route, leading to inefficient packet delivery and performance degradation.

Proposed System

To address the limitations of the existing system, we propose a novel approach to improve the performance of the AODV routing protocol in MANETs. Our proposed system aims to reduce overhead, latency, and improve routing efficiency to enhance the overall network performance.

Advantages

– Reduced overhead: Our proposed system minimizes the number of control packets generated, leading to lower network traffic and overhead.
– Lower latency: By optimizing the route discovery process, our system decreases route discovery time and reduces end-to-end delay.
– Improved routing efficiency: Our system ensures that the most optimal route is selected, enhancing packet delivery ratio and overall network performance.

Features

Our proposed system includes the following key features:
– Route optimization: Our system optimizes the route discovery process to find the most efficient path from the source to the destination.
– Control packet reduction: By minimizing the number of control packets, our system reduces network overhead and improves efficiency.
– Performance evaluation: We conduct extensive performance evaluations to compare the proposed system with the existing AODV protocol and demonstrate its effectiveness.

Conclusion

In conclusion, the performance evaluation of the AODV routing protocol in MANETs is crucial to identify its limitations and propose solutions to enhance network performance. Our proposed system aims to address the drawbacks of AODV by reducing overhead, latency, and improving routing efficiency. By implementing our system, we can optimize the performance of MANETs and ensure reliable and efficient communication in mobile ad hoc networks.
