Omnet++ is a discrete event network simulator for various networks. We run Omnet++ under various interfaces. We use graphical and animated user interface for demonstration and debugging process. We adopt command line interface for batch execution. We offer Omnet++ Projects in MS to develop academic projects with various modules. We support and guide MS students to do simulation projects in communication and network area. We implement wireless communication projects with INET simulator. We also support and implement more advanced projects in network for MS students.

INET Simulator:

We use INET simulator to implement communication network. We implement INET for wired and wireless network protocols. We construct INET models to create simulation models for nodes and networks. We support communication network with own defined protocols by INET.

INET framework support communication protocol such as TCP (Transmission Control protocols), IP (Internet protocol) and network Protocol such as point to point protocol and Ethernet. To access and share audio files by audio and destination address are supported by voice by IP in INET.

Wireless Communication:

For transmission of data and voice by electromagnetic waves in open space, we use wireless communication. Every channel have fixed frequency bandwidth and bit rate. We use different channels to transmit information in parallel and independent.

Types of Wireless Communication:

We used following types in wireless communication in more than 75+ projects are:

  • Microwave Transmission: Used for long distance communication and expensive.
  • Light wave Transmission: It act as laser and create unidirectional communication without license.
  • Radio Transmission: It provides Omni directional data transfer and ensure to travel long distance, penetrate through different buildings.
  • Infrared and Multimeter waves: Used for short range communication we apply infrared waves in indoor wireless local area network.

Advantages of Wireless Communication:

We use following advantages are:

  • Provides Easy Network Access.
  • Cheaper To Install And Maintain.
  • Ensure Solution Where Cables Are Impossible To Install.

MAC Protocols in Communication:

We implement medium access control layer for power consumption in wireless networks. We use this protocol for limited node energy and increases network lifetime.

Medium Access Scheme:

In wireless communication we implement medium access scheme for less cost and power consumption. We widely use Frequency Division Multiple Access (FDMA), CDMA (Code Division Multiple Access (CDMA) and Time Division Multiple Access (TDMA) which derived from Science Direct paper.

We utilize TDMA based MAC protocol to avoid collision in network and FDMA based MAC protocol to check bandwidth slot for uplink and downlink transmission. We support Omnet++ with simplex, duplex, half duplex communication.
