What is NS3 Network Simulator

What is NS3 Network Simulator – It is a network simulator that is enhanced to afford an exposing, flexible network simulating platform that has the purpose of education and to perform research. To be precise, Ns-3 offers the way of data networks and purposes to define the way of packet Named data networking Simulator and in addition, it offers the user’s simulation engines to perform simulation experiments.

Overview of NS3 Network Simulator

“Through this article, we attempt to define the concepts of NS3 simulation in a network and its performance criteria to evaluate the network’s performance and in this article; we implement our experimental knowledge over the NS3 in order to enrich your interest to initiate research on the NS3 network simulator domain!!”

To implement a simulation process, we should have user equipment like any wired or wireless communication device, which has connected to the internet. Using the device as a medium, we can perform the simulation. Here we provide you with the User Equipment PHY measurements Model.

UE PHY Measurements model

The User equipment has to generate report a set of criteria of the eNB, which the system is capable of observing, and thThe User equipment has to generate a report of a set of criteria of the eNB, which the system is capable of observing, and the user equipment has also recorded such criteria in addition to the PCI. The criteria are,

• Reference signal received power (RSRP)
• Reference signal received quality (RSRQ)

For the above report of the user equipment, must be functioned at the Receiving Signal RS, whereas the Physical Cell Identity is received with the PSS. In addition to the criteria reporting action of the UE, we provide you the process of The above report of the user equipment must be functioned at the Receiving Signal RS, whereas the Physical Cell Identity is received with the PSS. In addition to the criteria reporting action of the UE, we provide you the process of scheduling in Network Simulator as followss

Scheduling process in NS3 Network Simulator

We can classify the scheduling process in the NS3 simulator into four categories as

• The FemtoForum MAC Scheduler Interface
• Round Robin (RR) Scheduler
• Maximum Throughput (MT) Scheduler
• Priority Set Scheduler

The FemtoForum MAC Scheduler Interface

To the best of our knowledge, we applied the particularized version of the NS3 Network Simulator in the (FFAPI) FemtoForum MAC Scheduler Interface as a group of intangible modules. The (FFAPI) fundamentals are categorized into

• SCHED (handles with the scheduling implementation)
• CSCHED (handles the scheduling configuration)

Apart from the mentioned classes of the FFAPI, the FFAPI defines the fundamental elements of two various types as

• Forms of REQ processing to the scheduler from the MAC layer
• Forms of IND/CNF processing to the MAC from the scheduler

When the above traits are scripted into in the programming language C++, we elaborate the upcoming intangible modules to apply the Service Access Points of the fundamental elements to concern the primitives of the following

• FfMacCschedSapUser: this type of class describes every C++ techniques in respect to the CSCHED fundamentals of CNF/IND kinds
• FfMacCschedSapProvider: this module describes every C++ techniques in respect to the CSCHED fundamentals of REQ types
• FfMacSchedSapUser: this module describes every C++ techniques in respect to the SCHED fundamentals of REQ types
• FfMacSchedSapProvider: this module is used to analyze all C++ methods that corresponds to the SCHED fundamentals for REQ type

In the following, some of the significant schedulers used for NS3 simulation are given in detail.

(1). Maximum Throughput (MT) Scheduler

The main objective of the MT scheduler is to exploit the entire eNodeB throughput. It allows every Resource Block to the UE which can obtain the extreme, modern RRI’s obtainable rate. In recent, the NS3 Network Simulator Maximum Throughput has the following versions:

• Time Doma

• Time Domain Maximum Throughput (TDMD): in this version, the MAC scheduler chooses User equipment of extreme feasible rate measured by CQI wideband. After this process, the MAC scheduler enables the UE in the recent TTI, by allotting every RBG.
• Frequency Domain Maximum Throughput (FDMT): in this version, the MAC scheduler assigns the RBG to the UE about the network that has an extreme doable rate measured by the CQI sub band.

(2). Round Robin (RR) Scheduler

It is a cool scheduler, separating the active flow resources. It applies the version of non-adaptive that involves the effort of allotting retransmission of RR, which utilized the similar allotting configuration of the real block, to uphold the identical MCS and RBGs. The RR scheduler executes the filtering of UL Channel Quality Indicator, corresponding to the characteristics in along in aspect with the UlCqiFilter as follows

• PUSCH_UL_CQI: in this filtering process, the PUSCH alone based on the CQI are deposited in the internal qualities
• SRS_UL_CQI: simply the SRS based on CQI are deposited in the internal qualities.

(3). Priority Set Scheduler (PSS)

Priority Set Scheduler is generally a QoS cognizable Scheduler that integrates the packet scheduling functions of the Frequency Domain (FD) and the Time Domain (TD) into a single scheduler. It panels the objectivity between UE and a particularized TBR.

As a matter of fact, the priority set scheduler chooses the UE initially with a filled buffer of RLC and it separates the buffer into two groups on the basis of TBR as the first set’s typical previous throughput rate is minimum to TBR and the set’s typical throughput amount is either maximum or equal to the TBR rate. In addition to the scheduling type and its process, which is more significant in NS3, we explain to you the process of handover in the NS3 Network Simulator.

Vertical Handover Simulation in Network Simulator

The model of Radio Resource Control sustains the UE mobility in a LINKED mode by appealing the Vertical Handover in Heterogeneous Network Projects procedure corresponding to the X2. In this NS3 Network Simulator process, the RRC functions on the source of intra-frequency and Intra-EUTRAN. In case of that, there are two ways to generate the handover procedure the former is to generate the simulation automatically by eNodeB RRCindividuals on the basis of UE capacities and in response to the chosen algorithm of handover. The Network Simulator’s latter way is to plainly generate the simulation operation by performing the LteEnbRrc::SendHandoverRequest technique.

In addition to the triggering methods of the handover process, let’s see the properties involved in the 3GPP LTE as follows.

• Network-controlled properties: the eNodeB of the source and the target network determines the time to generate the handover and supervises its function
• UE-assisted properties: In this property, the UE offers the network input in the measurement recording types. This process of handover is dealt by the measurements model of UE RRC.

To the best of our knowledge, the handover algorithm functions at the eNodeB source and it is liable for determining the handover process in automated mode. It relates through the interface of Handover Management SAP of the eNodeB RRC incorporations. Bu the way, the NS3 Network Simulator following methods are the parts of the handover algorithm interface

• Trigger Handover (Handover Algorithm -> eNodeB RRC): is used to alert the individuals of eNodeB RRC about the determination of triggering the handover that will progress the handover procedure initiation.
• AddUeMeasReportConfigForHandover (Handover Algorithm -> eNodeB RRC): this method is utilized to get the measurement reports from the eNodeB RRC entity, by transmitting the required configuration report to implement it to every UE involved
• ReportUeMeas (eNodeB RRC -> Handover Algorithm): it functions on the basis of organized UE measurements previously to supplement with the UeMeasReportConfigForHandover, where the UE provides the measurement reports to eNodeB. The handover algorithm then receives the report from ReportUEMeas.

The above are the methods and their functions involved in the handover procedures of the NS3 Network Simulator. Along with the above-cleared methods for your reference, we’ve reached the core part of this article. In the following part, we offer you some project titles suggested by our project developers.
