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.

 

Preview of Game 7 between the 76ers and Celtics: Predictions, Odds and Player Props to Consider (May 14). While the basketball court heated up as rival teams battled to win the championship, the tech-savvy crowd had their own field to explore in detail, namely the OPNET network simulator. Just as fans scrutinized every game and player’s performance, network engineers scrutinized the simulated behavior and performance of complex networks. While fans pondered the outcome of Game 7, the odds seemed so volatile as the fate of the 76ers and Celtics hung in the balance. Just as basketball analysts looked at player stats, network engineers evaluated various parameters and configurations to keep their networks running smoothly.

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
