Opnet Simulation Tool
Opnet Simulation Tool for Device to Device communication:
D2D communications is about enabling the direct flow of data between devices. In contrast to Human-to-Human (H2H) communications, D2D communications do not require human interaction.
Types of D2D communication:
- Direct relaying with operator controlled link establishment (DR-OC)
- Direct D2D communication with device controlled link establishment (DC-DC)
- Device relaying with device controlled link establishment (DR-DC)
- Direct D2D communication with operator controlled link establishment (DR-DC)
Challenges on D2D communication:
- Optimization of power consumption
- Optimization of resource allocation
- Reuse of cellular frequencies
- Relay selection
- Multicast services in cooperative systems
- Interference management
- Security of the network
