Mobile Ad hoc Networks (MANETs) consist of wireless nodes operating without the need for fixed infrastructure. Due to their simple deployment, cost-effectiveness, and efficient communication capabilities, MANETs have become a prominent focus in wireless communication research. However, several inherent challenges arise from the limited energy resources of nodes, high mobility, and the continuously changing network topology, which frequently disrupts established routes and necessitates the discovery of new ones—leading to increased latency and resource consumption. AOMDV [1] has been proposed to address these issues by enabling multipath routing, yet it introduces higher routing overhead. In this study, we propose an enhancement to reduce the control overhead of AOMDV by incorporating gossip-based flooding, called GAOMDV (Gossip-based flooding AOMDV). Through simulation and performance evaluation on NS2, our results demonstrate that GAOMDV outperforms AOMDV in terms of normalized routing overhead, number of route request packets, and average end-to-end delay.

摘要

Mobile Ad hoc Networks (MANETs) consist of wireless nodes operating without the need for fixed infrastructure. Due to their simple deployment, cost-effectiveness, and efficient communication capabilities, MANETs have become a prominent focus in wireless communication research. However, several inherent challenges arise from the limited energy resources of nodes, high mobility, and the continuously changing network topology, which frequently disrupts established routes and necessitates the discovery of new ones—leading to increased latency and resource consumption. AOMDV [1] has been proposed to address these issues by enabling multipath routing, yet it introduces higher routing overhead. In this study, we propose an enhancement to reduce the control overhead of AOMDV by incorporating gossip-based flooding, called GAOMDV (Gossip-based flooding AOMDV). Through simulation and performance evaluation on NS2, our results demonstrate that GAOMDV outperforms AOMDV in terms of normalized routing overhead, number of route request packets, and average end-to-end delay.
