To simulate Mobile Ad Hoc Networks (MANETs) using OPNET has sequential steps that encompass to make a network in which mobile nodes can actively start connections and interact with each other deprived of fixed infrastructure. MANETs are frequently utilized within situations such as disaster recovery, military communications, and vehicular networks. We will guide you on how to configure and execute the MANET simulation in OPNET:
Steps to Simulate MANET Projects in OPNET
- Define the MANET Network Topology:
- Configure a topology with mobile nodes, which signify devices such as smartphones, laptops, or vehicles.
- Organize nodes reflects the environment, like a battlefield, disaster area, or urban network along with mobile vehicles.
- Every single node performs as both a host and a router, which actively establishing paths to other nodes because MANETs contain no fixed infrastructure.
- Select and Configure MANET Routing Protocols:
- OPNET supports multiple ad-hoc routing protocols are modified for dynamic, infrastructure-less networks:
- AODV (Ad hoc On-Demand Distance Vector): A reactive protocol, which discovers the routes on demand and sustains them only when required.
- DSR (Dynamic Source Routing): Alternative reactive protocol in which routes are determined and sustained by source nodes.
- OLSR (Optimized Link State Routing): A proactive protocol, which sustains routing tables including often updated data on network topology.
- TORA (Temporally-Ordered Routing Algorithm): Appropriate for highly dynamic networks, TORA sustains numerous paths to manage topology changes.
- Allocate one of these protocols for each node via the Node Model Editor or directly within the replication interface.
- Define Mobility Models for MANET Nodes:
- By reason of mobility is a describing characteristic of MANETs, which configure realistic mobility patterns:
- Random Waypoint Mobility: Nodes arbitrarily move within the simulation area that generally utilized for MANETs.
- Predefined Paths: It is helpful for replicating particular routes such as vehicular networks following highways or city streets.
- Group Mobility Models: Mimic sets of nodes are moving all together that helpful for military or emergency scenarios.
- Set up parameters like node speed, pause time, and movement boundaries to reflect the environment of network.
- Set Up Traffic Models and Application Profiles:
- Use Application Configuration and Profile Configuration to describe the application profiles, which make diverse kinds of network traffic that based on the use case:
- VoIP or Video: Replicate the real-time communication which needs low latency using constant bit rate (CBR) traffic.
- FTP or Web Traffic: Set up bursty traffic patterns replicating data transfer and browsing activities.
- Messaging: Configure small and periodic messages to mimic low-bandwidth applications such as text updates within emergency scenarios.
- Allocate the traffic profiles to nodes making realistic load on the network.
- Configure Power Management (Optional):
- Set up power-saving settings for battery-powered MANET nodes:
- Place the nodes to function in sleep mode when idle and wake up while required, which replicating real-world power constraints.
- Monitor battery life and energy consumption to measure the network longevity that is significant in energy-sensitive environments such as sensor-based MANETs.
- Run the Simulation with Defined Parameters:
- Set the simulation parameters like duration, event capturing intervals, and node start positions.
- Then, we execute the simulation and monitor how nodes interact, then how routes are established, and the network adjusts to topology changes within real-time.
- Analyze Key Performance Metrics:
- Utilize OPNET’s analysis tools to estimate the MANET’s performance that concentrating on the following crucial metrics:
- Throughput: Assess the data rate to estimate the network capacity and efficiency.
- End-to-End Delay: Compute how long it takes for information to travel from source to destination, which especially for real-time applications.
- Packet Delivery Ratio: Estimate the ratio of effectively delivered packets to those transmitted then showing network reliability.
- Route Discovery Time: Monitor how long it takes for routes to be launched that specifically crucial for reactive protocols such as AODV and DSR.
- Hop Count: For packet delivery, calculate the average amount of hops to compute the efficiency of the routing paths.
Example MANET Project Ideas
- Performance Comparison of AODV and DSR: Configure a MANET along with AODV and DSR protocols, which equating its performance such as end-to-end delay, packet delivery ratio, and route discovery time under changing node speeds.
- MANET for Disaster Response: Replicate a disaster area in which mobile nodes signify the rescue teams that utilizing TORA to sustain several paths, and then examine connectivity, reliability, and energy consumption.
- Vehicular Ad Hoc Network (VANET): Set up a MANET for vehicular interaction using OLSR along with nodes following predefined paths denoting the roads. Examine the effect of node density and speed on throughput and delay.
- Energy-Efficient MANET Protocol: Design a MANET including power management settings, then equating the energy efficiency and network lifetime of nodes utilizing sleep-wake cycles.
