Steps to Simulate Network Routing Projects in OMNeT++
- Install OMNeT++ and INET Framework
- OMNeT++ is the core simulation platform, since the INET framework deliver modules for network communication, has contain several pre-built routing protocols like OSPF, RIP, and BGP.
- Install both OMNeT++ and INET, as INET contain many models and functionalities for routing.
- Select Your Network Type
- Wired Networks: Implement routing in Ethernet-based networks or wide-area networks (WAN).
- Wireless Networks: Execute routing protocols for mobile ad-hoc networks (MANETs), wireless sensor networks (WSNs), or Wi-Fi networks.
- Mesh or Ad-hoc Networks: we can also discover multi-hop routing in mesh and ad-hoc networks in which nodes interact without centralized infrastructure.
- Routing Protocol Selection
We can choose to replicate standard routing protocols or generate custom protocol. Some examples of common routing protocols are:
- Distance Vector Protocols:
- RIP (Routing Information Protocol): Uses hop count as a routing metric, suited for smaller networks.
- AODV (Ad-hoc On-demand Distance Vector): Utilized in wireless and ad-hoc networks.
- Link State Protocols:
- OSPF (Open Shortest Path First): A widely used protocol in large networks.
- OLSR (Optimized Link State Routing): Utilized in mobile ad-hoc networks.
- Hybrid Protocols:
- EIGRP (Enhanced Interior Gateway Routing Protocol): Integrates the features of both distance vector and link-state protocols.
- Custom Routing: Execute custom routing protocol to replicate a certain routing algorithm, like load-balancing, fault-tolerant, or energy-aware routing.
- Set up Network Topology
- Describe the layout of network in NED files (Network Description). We can replicate simple topologies such as a small LAN with routers or more complex WANs with multiple routers and subnets.
- In wireless networks, nodes can move dynamically, and routes must be introduced and adapted based on varying topology.
- Utilize Ethernet switches, routers, hosts, and access points as part of network topology to replicate real-world scenarios.
- Configure the Routing Protocol
- Configure the routing protocols using INET or custom implementation. For example:
- For RIP, set up routers to inter change routing tables with their neighbours.
- For OSPF, configure areas and cost metrics for routes.
- For ad-hoc or wireless networks, setting up protocols such as AODV or DSR that build routes enthusiastically as needed.
We can design these protocols across OMNeT++’s INI file to adapt parameters like hello intervals, route discovery methods, link costs, or metrics.
- Traffic Generation
- Describe the traffic in network using application protocols such as:
- TCP: For reliable communication between nodes.
- UDP: For lightweight, connectionless data transmission.
- We can replicate traffic flows such as file transfers, video streaming, or real-time voice communications. Utilize constant bit rate (CBR) or variable traffic loads to replicate realistic conditions.
- In ad-hoc networks, traffic patterns change dynamically as nodes join, leave, or move.
- Measure Routing Performance
OMNeT++ delivers a range of tools to measure the performance of routing protocol. Common performance metrics include:
- Routing Overhead: Assess the control message overhead created by routing protocols. In dynamic networks, this overhead can affects overall network performance.
- Packet Delivery Ratio: The ratio of successfully delivered packets to the total number of packets sent.
- Average End-to-End Delay: The average time it takes for a packet to travel from the source to the destination.
- Jitter: Variation in packet arrival times, significant for real-time applications.
- Path Length (Hop Count): Evaluate the average number of hops taken by packets to reach their destination.
- Mobility Models (for Wireless Routing)
- For wireless routing projects, simulate mobility using models like:
- Random Waypoint Mobility: Nodes move randomly within a bounded area.
- Manhattan Grid Mobility: Ape urban environments in which the nodes follow streets.
- Gauss-Markov Mobility: Mimic realistic node movement with memory of previous movement patterns.
- Routing protocols such as AODV, DSDV, and OLSR can be validated in dynamic topologies to monitor how well they adjust to network changes.
- Simulate Network Failures and Link Breakage
- Establish node or link failures to validate the fault tolerance of routing protocols.
- In wired networks, simulate link failures or router outages and monitor on how the routing protocol converges to a new topology.
- In wireless or ad-hoc networks, replicate node mobility or energy depletion to monitor the routing protocol’s ability to recover from broken links.
- Security and Attack Simulations
- Execute security mechanisms like an encryption for routing messages to mitigate tampering and eavesdropping.
- Simulate attacks like:
- Blackhole Attacks: Where malicious nodes drop packets.
- Wormhole Attacks: Where two malicious nodes generate a tunnel to route packets, bypassing the network’s intended path.
- Routing Table Poisoning: Where nodes advertise incorrect routes, disturbing network performance.
Measure on how routing protocols deals with these security attacks and whether they recover effectively.
- Energy-Aware Routing (for WSNs)
- In Wireless Sensor Networks (WSNs), energy efficiency is vital. Execute energy-aware routing protocols in which nodes forward packets according to their remaining energy levels.
- Evaluate network lifetime that signifies how long the network continues functioning before nodes initiate dying because of energy depletion.
- Utilize energy consumption models in frameworks such as Castalia to accurately replicate energy usage in the course of data transmission, reception, and idle states.
- Visualization and Results
- OMNeT++ enables for real-time visualization of packet flows, node movements, and routing updates. This supports in familiarizing on how the routing protocol performs within the network.
- Envision routing tables, packet forwarding, and route discovery processes. OMNeT++ delivers detailed statistics and graphs for measuring the outcomes of simulations.
- Project Ideas for Network Routing
- Routing in MANETs: Replicate and relate the performance of numerous routing protocols such as AODV, DSR, and OLSR in dynamic mobile ad-hoc networks.
- Energy-Aware Routing in WSNs: Mimic a wireless sensor network and execute routing protocols that enhance energy usage for prolonging network lifetime.
- Routing in 5G Networks: Replicate next-generation routing approaches for 5G networks that contain multi-path routing or network slicing.
- Dynamic Routing in IoT: Execute routing protocols for large-scale IoT networks in which devices are heterogeneous and resources are constrained.
