Abstract:
Mobile Ad Hoc Networks (MANETs) exhibit severe topological instability caused by high node mobility, which induces frequent packet dropouts and excessive control message routing overhead. Conventional on-demand distance vector protocols face transmission drops under rapid speed fluctuations. This paper presents an optimized protocol variant, Link-Stability Predictive Vector (LSP-AODV), which incorporates real-time relative distance, direction vectors, and radio signal indicators directly into the path-finding mechanism. By predicting the connection lifespan between mobile points, the routing protocol proactively calculates alternative network channels before active links separate. Simulation runs were executed across a realistic 5 square kilometer urban mobility scenario with varying velocities. The results indicate that LSP-AODV expands the overall packet delivery ratio by 28.6% and drops routing message control overhead by 34.1% at node speeds reaching up to 100 kilometers per hour. Total end-to-end routing latency dropped by 45 milliseconds, complying with the stringent requirements needed for multimedia data traffic. This framework successfully optimizes multi-hop packet throughput across volatile network fields.
