This page is all about to implement NS3 5G Simulation Research Projects.
“NS3 is an influential simulation tool, which is meant to overlay research path for the ones thrive to be the best one in researching one”
Overview of NS3 5G Simulation
5G networks are having promising features based on their notable ability to incorporate the following communication networks of
- Industry 4.0
- Vehicular to Vehicular (V2V) communication
- Device-to-Device (D2D)
- Machine-to-Machine (M2M)
- Internet of Things
Along with the above special integrating features of the 5G network, it has another important aspect to induce the access point density with the structures that can afford lenient HetNet transference solutions. Besides the 5G overview, we provide you the main objectives of the 5G network as follows
“This article highly focuses on unlocking the research aspects of 5G networks and envisaging the features and functions of NS3 simulator and effective impact of NS3 simulator implementation over 5G networks, in addition with our research services!!”
Main objectives of 5G network
- 5G network is able to supply low latency as instant response
- It can affords uniform user experience
- 5G has sustained, standard data rate even in the user mobility
- 5G network is structured to afford optimized network capacity in the new spectrum like mmWave
- 5G network has the infrastructure to supply high data rates up to 20 Gbps
The exceeding features can be considered as the important purpose of the 5G network. In addition to the objectives of the 5G network, we provide you with the comparative features among the 4G and 5G networks as follows.
Major advantages of 5G above 4G
The 5G network isThe 5G network is typically an evolving technology with more facilities when evaluating the advantages of 5G over 4G. The 5G network is higher than 4G in higher terms of
- Efficiency
- Upload/download speed
- Capacity
- Bandwidth
And lower in terms of interference and delay. These are the power of 5G features apart from the basic cellular network without any flaws it sustains other ISPs according to the user needs. In addition to the emerging advantages of 5G networks, we afford you the transformer mode of NS3 5G Simulation networks.
Components of 5G transformer model
In this model, we highlight the 5G transformer network, which consists of three major planes differentiated as follows
- Mobile Transport Computing Platform: it refers both the physical and virtual substructures, where the network slices are formed.
- The Vertical Slicer: it is the topmost Service Orchestrator aimed to produce modifying slices and it decreases the time of service creation
- Service Orchestrator: it serves as an end-to-end service responder and organizing either the resources of transport and calculation through single or several MTP
Among the above major planes, the MTP is a combination of two folds namely,
- Optical architecture on the basis of the Xhaul model (with the resources of P2P optical fibers)
- Access network on the basis of LTE
It has to be noted that these are the fundamental functions and our engineering team is putting their effort to utilize the 5G components for various real-time usage and we are just meeting the aspect of NSA 5G on the plan basis of 3GPP. Besides the 5G transformer model, we provide you with our NS3 5G Simulation modelling.
Important NS3 5G channel modeling
MIMO
This 5G model embedded with multiple antenna beamforming is necessary to assure the average range of mmWave system communication because of the maximum path loss in 5G network
- Beamforming: to sustain the segmented array antennas, the new class called AntennaArrayModel is optimized, which has a compound vector of beamforming. These vectors (for transmitter and receiver) are calculated using the power algorithms, on the basis of channel matrices
- Chanel matrix: we have designed the mmWave channel as a cluster mixture and each of its composed with various sub routes.
mmWave Propagation Loss Model
Generally, the mmWave model of path loss can be modeled in three various conditions like an outage, Non-Line of sight (NLOS), Line of Sight (LOS). In this case, the channel is determined by the following process,
- The chances of link in all the three conditions are decided on the basis of space among UE and eNB.
- Evenly selecting a PREF reference value among 0 and 1 and the possibility linked with the conditions of every state
The above details are the channel modeling for the 5G network specified on MIMO. It generally includes the two fundamental processes as described above. In case of that, we have to take a look at the MAC and PHY layer of communication as we have given below
Process of communication between the MAC and the PHY layer in NS3
The common communication process is occurring among the MAC and the PHY layer in ns-3 simulator is based on the MAC-PHY SAP, which is happening via the following process
Data Transmission
The MAC layer of the eNB upholds the data queue for every linked UE and the user device can be satisfied with a single queue. After that, the MAC layer transmits the scheduled amount of packets based on its scheduling system to the PHY layer through the radio link for data transmission.
Sub frame Indication
At the beginning point of every slot, a sub-frame indication will be sent to the MAC layer by the PHY layer, which is different from the LTE network, which sends the indicator to every sub-frame. A specified sub-frame activates the scheduling procedure for the eNodeB Mac occurs at slot 1. In addition to the sub-frame indication, the following indications are needed for the regular data supply belonging to the upper layer in implementing ns3 5g simulation..
CQI notification
The PHY layer of the user equipment computes the CQI and transfers the calculated data to the base station of the uplink control slot, situating next to it. This process occurs on the basis of the received SINR slots. Transmitting the mmWaveCqiReport message to the MAC, this was received by the PHY layer of eNodeB.
Scheduling and allocating Notifications
This process occurs in the PHY layer of the base station that seizes to transfer the message to all the linked users by alerting all the schedule determining devices by using the mmWaveResourceAllocation message. The scheduling and the allocating process actually initiates the receiving in the MAC layer with the help of eNB.
The above are the four ways of communication that happen between the PHY and Mac later of the network and we can consider the above communication process as the significant way of transmitting the data also. Besides the exceeding communication process, let’s have a look at the parameters applied on the mmWave structure of the 5G network as follows.
