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
