Benefits

Using the MANET block in VisualSim provides:

  • Realistic Mobility Modeling: Accounts for node movement and dynamic topology.
  • Routing Flexibility: Supports multiple routing strategies for comparative studies.
  • Scalability: Evaluate network behavior with dozens to hundreds of nodes.
  • Latency & Throughput Insights: Quantify performance under changing conditions.
  • Fault Tolerance: Explore resilience to node/link failures.
  • Cross-Domain Usability: Apply the same framework to defense, automotive, aerospace, IoT, and industrial systems.

The MANET (Mobile Ad Hoc Network) Node Network block in VisualSim models self-organizing wireless networks where nodes communicate directly or via multi-hop forwarding, based on their X,Y coordinates and transmission range. Unlike traditional infrastructure-based networks, MANETs operate without fixed base stations, making them ideal for dynamic, decentralized, and mobile environments.

The concept of MANETs emerged in the 1990s with the growth of wireless research, led by organizations such as DARPA and research institutions working on military battlefield communications and disaster recovery systems. Over time, MANETs have become central to vehicular ad hoc networks (VANETs), drone swarms, IoT deployments, and emergency response systems.

The MANET block in VisualSim lets engineers simulate node movement, routing strategies, connectivity changes, and packet traffic, enabling accurate evaluation of latency, throughput, routing efficiency, and fault tolerance.

Overview

The MANET block includes:

  • Mobile Nodes (Node_1, Node_2, etc.): Wireless devices that move dynamically and transmit data.
  • Message Source (Trans_Src): Generates and sends traffic to destination nodes.
  • Routing Mechanism: Dynamically selects the best path based on position and connectivity.
  • Statistics Block: Collects metrics such as throughput, packet delivery ratio, and latency.
  • Dynamic Topology Management: Nodes continuously update their neighbor tables as they move.
  • Multi-Hop Forwarding: Data can traverse multiple intermediate nodes to reach its destination.

Supported Standards

The MANET block supports modeling aligned with:

  • IETF MANET Working Group Protocols: AODV (Ad hoc On-Demand Distance Vector), OLSR (Optimized Link State Routing), DSR (Dynamic Source Routing).
  • IEEE 802.11s: Mesh networking extensions for Wi-Fi.
  • ETSI ITS-G5 / DSRC: Vehicular ad hoc communication standards.
  • Zigbee/6LoWPAN extensions: Used in IoT and industrial ad hoc systems.
