Evaluating Mobility Models for IH-VANETs: A Simulation-Based Analysis

Intelligent Heterogeneous Vehicular ad hoc networks (IH-VANETs) are more dynamic due to the mobility of vehicles. Routing packets along efficient paths improves the efficiency of the routing schemes. Relying on efficient mobility models for traffic generation for real-time road scenarios is conducive to efficient routing. This work presents and evaluates the performance of various mobility models including the Random Waypoint Mobility Model (RWP), Intelligent Driver Model (IDM), Intelligent Driver Model-Intersection Management (IDM-IM), and Manhattan Mobility Model (MMM). The reactive protocol such as Dynamic Source-Routing (DSR) is used with mobility models to evaluate the efficiency in the form of Packet Loss Ratio (PLR), End-to-End Delay (EED), Throughput (T), Packet Delivery Rate (PDR), and Overhead of routing (OR). DSR and mobility models are implemented in Network Simulator (NS 2.35). Simulations show that utilizing real-time traffic with mobility models affects DSR performance in all aspects.
