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
