Opnet Tutorial for Beginners

Opnet Tutorial for beginners ensure an optimum network performance and application analysis based on C++ with strong GUI. OPNET is a prominent discrete event network based simulator. We develop PhD thesis in Opnet for various background such as computer science, information system and electrical engineering. We support and guide students to achieve benefits in model library with source code, specialized model such as WiMax, UMTS, WPAN, MPLS, IPV6, MANET. By Opnet PhD  Network Thesis we attain simulation event, analytical model, and hybrid technology ensures scalable, and high –fidelity simulations. We provide platform to share an innovative ideas to other users and ensure support to publish IEEE papers or other journals.

WPAN OPNET Tutorial for beginners: We provide WPAN composed of various nodes distributed in a given area to measure monitor physical deployment and logical topology organization. We use 802.15.4 WPAN OPNET simulator.

OPNET Modeler System: We use Opnet modeler to develop and use graphical user Interface. We support various simulation models with point to point, ring, mesh and star, cluster Topologies. We establish communication among devices by a controller called PAN coordinator.

Devices: We use different devices for OPNET are:

• PAN Coordinator.
• End Device.

Layered Node Model: We ensure following layers with OPNET are:

• Physical Layer – We use physical layer for transmission and IEEE 802. 15.4

specifications with operating at 2.4 GHZ and data rate to 250 Kbps.

• MAC Layer – We implement MAC layer with slotted CSMA/CA.
• Network Layer – we use network layer for end to end packet delivery includes routing

by intermediate host.

• Application Layer– we use application layer to generate and traffic reception.

WPAN Topologies Opnet Tutorial for beginners: We performed and implemented WPAN simulations in more than 85+ projects with various topologies and we measure the following parameters are:

• Throughput: We calculate throughput as average number of packets or bits received successfully are transmitted by receiver or transmitted channel per second.
• Data Traffic Sent: We calculate data traffic sent as total number of data bits are sent by source to destination per unit time.
• Data Traffic Received: We calculate data traffic received as number of data bits received per unit time.

Packets Dropped: We determined and handled packet drop in more final year projects as packet that are unable to

reach destination from source and may lost due to following factors as:

• Packet Corruption.
• Signal Degradation.
• Network Driver Fault.
• Oversaturated Network Links.
• Network Hardware Fault.
