Receiver-Based Ad Hoc On Demand Multipath Routing Protocol for Mobile Ad Hoc Networks

Area of Science:

• Computer Science
• Networking
• Mobile Computing

Background:

• Mobile ad hoc networks (MANETs) face challenges with frequent link breaks due to node mobility.
• Reactive routing protocols often incur significant route rediscovery delays, impacting network performance.
• Multipath routing enhances reliability but requires efficient path update mechanisms, especially under high mobility and traffic.

Purpose of the Study:

• To propose an improved multipath routing protocol, Receiver-based ad hoc on demand multipath routing protocol (RB-AOMDV), to reduce route rediscovery time.
• To enhance the reliability and efficiency of routing in mobile ad hoc networks.
• To address the limitations of existing protocols like Ad hoc On-Demand Multipath Distance Vector (AOMDV) in terms of delay and path maintenance.

Main Methods:

• Developed the Receiver-based ad hoc on demand multipath routing protocol (RB-AOMDV).
• Modified the traditional sender-initiated path discovery to a receiver-initiated approach.
• Evaluated RB-AOMDV performance through simulations, comparing it against the AOMDV protocol.

Main Results:

• RB-AOMDV significantly reduces route rediscovery time compared to AOMDV.
• The proposed protocol demonstrates improved packet delivery ratio.
• Simulation results indicate lower end-to-end delay in RB-AOMDV under various network conditions.

Conclusions:

• Receiver-initiated path discovery is an effective strategy for reducing route rediscovery latency in MANETs.
• RB-AOMDV offers a more efficient and reliable multipath routing solution for mobile ad hoc networks.
• The findings suggest RB-AOMDV is a promising protocol for high-mobility and high-traffic MANET environments.
