To simulate a Vertical Handover project in OPNET, we will required to concentrate on designing the various wireless networks like Wi-Fi, LTE, and 5G and configuring the handover mechanisms to shift effortlessly among these networks according to the factors such as signal strength, bandwidth, or user-defined policies.
Here’s a step-by-step procedure to configuration such a simulation:
Steps to Simulate Vertical Handover Projects in OPNET
- Define the Network Architecture:
- Configure different wireless networks, like Wi-Fi, LTE, and 5G, to denote the varied networks that includes in vertical handover.
- Utilize OPNET’s Node Model Editor to asset up numerous access points (APs) for Wi-Fi, eNodeBs for LTE, and gNodeBs for 5G.
- Place these network nodes in the replication scenarios with overlapping coverage areas to enable for handover surroundings.
- Configure Mobile Nodes:
- Generate mobile nodes like users with smartphones or vehicles which can transmit via the network coverage areas.
- Allocate diverse interfaces to each mobile node to permit connectivity to each network type such as Wi-Fi, LTE, and 5G.
- Describe undertaking patterns for the mobile nodes using mobility profiles to replicate realistic movement via the networks.
- Set Up Handover Triggers:
- Describe condition for starting a vertical handover. The usual cause that contain Received Signal Strength Indicator (RSSI), Signal-to-Noise Ratio (SNR), network congestion, or user preferences such as switching to Wi-Fi if available.
- In OPNET, we can execute this condition by configure threshold values for metrics such as RSSI and SNR in the node or execute the design.
- Implement the Handover Decision Algorithm:
- Design the decision-making process for vertical handover. This can contain an multiple condition:
- RSSI-based decision: If the signal asset of the present network falls below a threshold, the node changes to a network with a stronger signal.
- Bandwidth-based decision: Change to a network with sophisticated available bandwidth when the present network becomes blocked.
- Cost-based decision: To select less expensive networks like switching to Wi-Fi when obtainable to minimize data costs.
- To execute these, utilize OPNET’s Process Model Editor to compose custom techniques which validate these conditions and begins with handovers when met.
- Set Up the Handover Process in the Simulation:
- Set up the simulation to track handover events among network interfaces on the mobile nodes.
- Execute custom entities in each mobile node to replicate the chosen network and update these features in the course of handover events.
- Utilize control packets or events in OPNET’s event-driven design to signal when a node changes from one network to another.
- Simulate Data Traffic and Handover Effects:
- Set up realistic traffic flows such as HTTP, VoIP, or video streaming to validate the performance of the vertical handover process.
- Set traffic origin and destinations via diverse network nodes and learn on how traffic flow is impacted by handover events.
- Run the Simulation:
- Implement the replication and learn the characteristics of mobile nodes as they transmit via different network coverage areas.
- Track the handover frequency, latency, and packet loss in the course of handovers.
- Analyse Results:
- Utilize OPNET’s evaluation tools to investigate key parameters:
- Handover latency: Evaluate the latency has includes in the transition from one network to another.
- Packet loss rate: measure packet loss in the course of the handover process to measure its effects on applications such as VoIP.
- Throughput: Evaluate the effects on throughput to learn the efficiency of the vertical handover decision techniques.
- Handover success rate: Regulate the rate at which handovers are successfully accomplished without service disruptions.
Example Vertical Handover Project Ideas
- QoS-based Vertical Handover: Replicate a handover mechanism which selects QoS-sensitive applications such as VoIP to a network with lower delay and higher bandwidth.
- Cost-Aware Handover: Execute cost-based handover techniques in which mobile devices desire Wi-Fi when accessible to minimize mobile data costs.
- Handover in High Mobility Scenarios: Validate vertical handover performance in high-mobility scenarios, like vehicles transmit via Wi-Fi and LTE/5G zones.
