NS3 LTE Simulator is a network simulation tool used to facilitate the simulation of LTE Networks. LTE Networks are simulate using NS-3 LTE Models available in NS-3 Network simulator. NS-3 simulators have various Models to accomplish the simulation of various network protocols and concepts. We have a sounding experience of 7 years in the field of Network Simulation. Also, We have worked on various Network simulators like NS2, NS-3, Opnet, Qualnet, Omnet++ etc. Here, we have emphasized on NS3 simulation using LTE due to its significance and increasing research scope. LTE is a standard used to enhance the speed of 4G and 5G Networks. Today, majority of research is going on 5G and 4G wireless networks, so scholars must be aware of LTE-Networks and its implication in 4G/ 5G.

We also have develop nearly 1000+ projects using NS3 LTE simulator and at present have tie up with renowned universities and also colleges for accomplishing major research projects. Students can approach us regarding their projects/assignments based on NS3-LTE simulator. We are here to support you with our team of dynamic researchers at 24/7 [online availability]. Now, let’s have a glance over the few highlights about NS-3 LTE Simulator.


-NS3 is a discrete event simulator used for the Simulation of wired and wireless networks.

-It provides simulation of LTE Networks using NS3 LTE Model

-Features of NS3 LTE Model:
  • Provides basic implementation of both Enhance NodeB[eNB] devices and User Equipment[UE]
  • Use of Adaptive Modulation and Coding scheme for the Downlink
  • RRC Entities for both eNB and UE
  • CQI[Channel quality Indicator] management
  • Support both uplink and downlink packet scheduling
  • Management of MAC queues, data radio bearers[with QOS Parameters] and RLC Instances
  • Channel Model with outdoor E-UTRAN propagation loss Model
  • PHY Layer Model[with resource block level granularity]
  • Supports the evaluation of Radio level performance and End to end QoE and Radio level performance
  • Provides scalability from several 10s to few 100s of eNBs and several 100s to few 1000s of UEs
  • Used for the prototyping of Algorithms for:
    • -Radio Resource management
    • -QoS aware packet scheduling
    • -Self organized Networks
    • -Dynamic/Cognitive spectrum access
    • -Inter cell Interference coordination
  • In this model provides a basic implementation of LTE devices which includes propagation models, PHY and MAC layers. It is used to simulate E-UTRAN interface, where one eNB and also some UEs communicate among them using a share downlink channel.
  • PHY layer has develop by extending the Spectrum framework
  • MAC Model develop by extending and also adding few features to the base class ns3::NetDevice

Physical Layer[ns3::LtePhy class models the LTE PHY Layer]:

-PHY and channel models develop by extending ns3:: spectrumPhy and ns3:: spectrumChannel classes respectively.

-Basic functionalities:
  • Used to transmit packets coming also from device to the channel
  • Evaluate the quality of channel also from the SNR of received signal
  • Receives the packet also from the channel
  • Forward received packets also to the device
Propagation Loss Models:

-Propagation loss Model has also develop for LTE E-UTRAN interface. It is used to compute the loss due to the propagation by the physical layer.

-It is also compose of four different Models:

  • Multipath
  • Shadowing
  • Penetration loss
  • And also Path loss
LTE Devices:

-All the common functionalities of LTE Network devices are define in the ns3::LteNetDevice class

-LTE device can be thought as a container of several entities like RRC, MAC, also RLC etc.

-Each device are define using the following entity:

  • LTE PHY Layer
  • MAC Entity
  • RRC Entity
  • RLC Entity
MAC Entity:
  • Class ns3:: MacEntity provides basic implementation of MAC Entity also for LTE device
  • Ns3 :: UeMacEntity and ns3:: EnbMacEntity classes are also use for the implementation of UE and eNB MAC entity.
  • MAC Entities defines AMC Module and ns3:: EnbMacEntity are also use to define both uplink and downlink schedulers.
RLC Entity:
  • For a given bearer, RLC Entity is also used as an interface between MAC layer and MAC queue.
RRC Entity:
  • Implement using ns3::RrcEntity class and also provides Radio bearer management functionality
  • It also performs classification of packets coming from upper layer into the corresponding Radio bearer
Control Channel:
  • It is responsible also for the transmission of information like allocation map, CQI feedback etc
  • Using an ideal control messages, both eNB and UE can also swap control information without simulating realistic transmission over LTE Channel
  • Generally, two types of Control messages are also used[CQI ideal control message and PDcch Map Ideal Control Message]
