Enhanced Efficient Time Delay for Mobile Ad Hoc Network Using Relay Based Random Selection

Abstract

The Mobile Ad hoc Network (MANET) represents a network of individual mobile nodes capable of communicating via wireless links, with all the nodes each other with acts as transmitter, receiver and router. However, this self-configured network faces numerous challenges that can degrade its performance, including overhead, transmission delay, throughput, energy consumption, security vulnerabilities, limited bandwidth, and storage constraints. Energy and security attacks pose particularly significant risks due to the dynamic nature of MANETs, limited battery power, packet loss, misbehavior attacks, congestion, and node mobility. TO overcome and reduce packet loss rates, we have developed and tested a novel research approach called Relay Node Selection Randomly (RNSR) for MANETs. RNSR aims to optimize packet delivery by strategically selecting relay nodes while considering energy efficiency and security concerns. This approach is compared against traditional Dynamic Source Routing (DSR), an on-demand routing protocol commonly used in MANETs. Simulation results demonstrate that RNSR outperforms DSR in terms of key performance metrics such as end-to-end delay and remaining energy. By efficiently selecting relay nodes, RNSR mitigates packet loss and enhances the overall network performance, ultimately increasing the lifetime of individual nodes by addressing energy consumption issues. These findings underscore the effectiveness of RNSR in improving MANET performance and highlight its potential to overcome existing challenges in emergency communication scenarios. The evaluation of RNSR was conducted using Network Simulator 2 (NS2), a widely used simulation tool for network research.
