Device to Device (D2D communication) is defined as direct communication with the devices without the medium of base stations (BS) or core network. In general, D2D communication is non-transparent to the cellular networks, but it can occur in the cellular frequencies and unlicensed spectrum. Learn An Efficient Resource Allocation Algorithm using D2D Communication Simulation.
D2D communication is not a small field, and it is one of the biggest fields in communication networks. It is divided into direct D2D, relaying device, and direct communication between devices with BS and relaying with BS. Let us discuss the four types of D2D communication in detail
What is the standard for communication between these devices?
- Direct D2D with Device Assisted Controlled Link
- Without any intervention as the control link from BS, the source and destination can communicate directly. Receivers check the device discovery before transmitting the data.
- Relaying Device with Device Assisted Controlled Link
- Through relays only the source and destination communicate with each other. The whole communication process is managed by the devices themselves. Thus, the process happens in the absence of BS.
- Direct Communication between Devices with BS Assisted Controlled Link
- When the source and destination communicate each other with the assistance of BS means it provides seven control links. Basically, BS deals with access authentication, connection control, interaction between the devices and resource allocation.
- Device Relaying with BS Assisted Controlled Link
- The resource allocation and call setting up in such a scenario is done by the base station. Due to centralized control, the interference can be avoided between the devices. It helps to increase the battery life of the device.
Above, we have discussed the types of D2D communication assisted with the controlled link. When we are ready to offer PhD guidance in D2D communication Matlab Code, we focus on the recent research ideas for your PhD research in D2D Communication Simulation.

Interference management in D2D Communication Simulation
For instance, let us check out the details of interference in D2D Communication Simulation. Interference is one of the insolvable issues in D2D communication. The interference model is based on the kind of MAC mechanism, and it is responsible for managing the channel access and avoiding packet collision. The prediction can be made by using the following metrics.
QoS Metrics in D2D Communication
- PDR (Packet Delivery Rate)
- BER (Bit Error Rate)
- PLR (Packet Loss Rate)
- SINR (Signal to Noise Interference Rate)
- SIR (Signal to Interference Rate)
- BER (Bit Error Rate)
The different interference mitigation approaches are classified into three major types: coordination, avoidance, and cancellation techniques. Now, let us take a look at interference techniques in detail. Performance Evaluation of Multihop D2D Communication Simulation.
Interference Management Techniques for D2D Communication
- Interference Coordination Techniques
- Power control schemes and proper scheduling helps to mitigate the interference between D2D and cellular links.
- Interference Avoidance Techniques
- Orthogonal time frequency resource allocation techniques help to avoid the interference between cellular links and D2D links.
- Interference Cancellation Techniques
- It has the ability to improve the capacity of cellular networks and it uses some advanced coding and decoding methods to cancel the interference signals.
To overcome the problem of interference D2D Communication in cellular networks, enormous algorithms have been proposed.
