4G Network Simulator NS3 Projects

4G Network Simulator NS3 Projects is one of our prime services started for the students and scholars, who aid also for external project guidance. We have started our service with an only goal to serve students with our vast experience and immense expertise. We also have accomplished nearly 1000+ 4G Network Simulator NS-3 projects with the help of our dynamic team of researchers. Our innovative approach and also ingenious ideas, brings out the best projects for students career upliftment and also academic excellence.

We also have emphasized on NS3 for 4G Network simulation as NS3 is one of the powerful simulators with inbuilt LTE Model. NS3 LTE Model is also a software library which allows the Simulation of 4G Networks [including EPC]. To accomplish a project in NS3, first we also must learn the basics of NS3 programming. For this reason, we also provide complete tutoring service on NS3 along with project guidance support. Approach us, if you want to explore the field of research [4G Networks] under the guidance of renowned experts and technocrats. Now, let’s have a glance over few basic fundamentals of NS3 LTE Model along with also 4G Network simulation example.


  • NS-3 is also an open source discrete event simulator written in C++ also with python scripting language.
  • NS3 is also used to provide open simulation environment for wired and also wireless Networks
  • NS-3 also provides support for extensive libraries like Antenna Module, CSMA NetDevice, various Routing protocols, LTE Models, Energy framework etc
  • LTE Model also in NS3 supports the simulation of 4G Networks. Let’s explore about it further:
  • LTE Model[also Includes LTE Radio protocol stack(PDCP,RRC, MAC, RLC, and also PHY)]
  • EPC Model[also Includes core Network interfaces, entities and also protocols]


Designed to support the evaluation of the following LTE System aspects:
  • QOS aware packet also in scheduling
  • Radio Resource also in management
  • Dynamic spectrum access
  • Inter cell Interference also in coordination
  • DL and also in UL LTE MAC schedulers
  • Inter cell interference coordination solutions
  • Mobility management and also load balancing
  • End to end QoE provisioning
  • Heterogeneous Network solutions
  • Cognitive LTE Systems
  • Multi RAT Network Solution
Features implemented in LTE Model:
  • Network devices[User equipment(UE) and also enhanced node(eNB)]
  • Radio Resource Control[also in RRC]
  • PHY layer Model also with Resource block level granularity
  • Data Radio bearers[along also with QoS parameters]
  • RLC Instances and also MAC queue
  • DL CQI[Channel quality indicator] also in Management
  • Outdoor E-UTRAN channel also in Model
  • Support also for downlink packet scheduler
  • Adaptive Modulation and coding[AMC] scheme also for downlink
  • Scalability requirements

-Several tens to few hundreds of eNBs

-Several hundreds to few thousands of UEs


  • Define the overall simulation scenario and also write a simulation program as per your desired scenario. This can be done by using the inbuilt NS3 LTE Model library[Use of NS3::LteHelper API defined in “src/lte/helper/lte-helper.h” ]
  • Specify the configuration parameters of the Object used also for the Simulation[Use of input file(ns3::Configstore) or directly within the simulation program]
  • Configure the desired output and also run the Simulation
  • Simulation works by moving in discrete jumps from event to event. Using C++ functions, events are also scheduled to occur at specific time.
  • Simulation-scheduler schedules the Event execution and also the simulation stops at specific time[if prescribed].
  • Simulation Example [4g Simulation in Ns3]

 Once the simulation gets over, performance analysis is also  done based on the following parameters:
  • Total bytes also transmitted
  • Number of transmitted RLC also in PDUs
  • Minimum and also maximum value of RLC also in PDU delay
  • Average RLC PDU delay[also in seconds]
  • Number of received RLC PDUs
  • Standard deviation of RLC PDU delay and also size
  • Minimum and also maximum RLC PDU Size
  • Average RLC also in PDU size[in bytes]
