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.
“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.
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,
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
We can classify the scheduling process in the NS3 simulator into four categories as
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
Apart from the mentioned classes of the FFAPI, the FFAPI defines the fundamental elements of two various types as
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
In the following, some of the significant schedulers used for NS3 simulation are given in detail.
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:
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
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.
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.
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
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.
