Long Term Evolution LTE Simulator

Long Term Evolution LTE Simulator

The term LTE stands for Long Term Evolution, which is an effective technique that improves the extreme performance of a network, particularly in the limitations of air. It is widely used for the purpose of cellular communications. It is used in mobile networks also to enhance the speed of data transmission and to enable fast browsing. Comparing to its previous generation networks like 2G and 3G, the LTE can be implemented in the 4G and in the future of the Internet, 5G network.

“This article discusses the importance of the LTE network, its research purposes and it displays our experimental experiences in the LTE simulator and through this article, we share with you some important aspects of the LTE simulator from the research point of view!!”

Some Real-time applications

Normal and emergency situation applications in smart grid: it is based on the smart grid LTE process along with the cellular smart grid components of 

  • Smart meters (SM)
  • Enhanced Smart Meters (eSM)
  • eNodeB
  • A Telco Network as a medium
  • DSO State Estimation and Real-time control
  • DSO Monitoring and Operations Center

Wireless multimedia systems applications:

The fundamental function of this application is to generate the data from the media server to transfer the wireless buffer to the base station and simultaneously, the user request on the data will be sent to the same base station. It then schedules the data to allocate the users respectively. This application can be broadly classified into

  • Interactive video (ITV)
  • Tele cooperation
  • Hypermedia application

There is always a wide range of chances available for multimedia applications. But the functions may vary according to the user request over the different data. In addition to the applications, we provide you the list of algorithms in the LTE simulator

Our Best Algorithms in the LTE simulator

BCQI downlink scheduling algorithm: this algorithm provides the best results and it prefers the VoID users in resolving the video traffic and prioritize the other traffics later. The simulation report of this algorithm is based on 

  • Improved average throughput in all users
  • Increased spectral efficiency development

Channel aware scheduling algorithm: it schedules the process of uplink and downlink in a network.

CQI (Channel Quality Indicator): This algorithm is a kind of scheduling method with the conditions of the best radio link, where this algorithm allots the resource blocks to the users and rise the cell ability at the cost of the equality endpoints of the terminals are far away from the base station because these terminals don’t come for the scheduling process. The scheduling process will be performed as follows

  • Terminals sending CQI to the base station
  • Transmitting base station signals to terminals via downlink pilot
  • Measuring CQI based on signals used by UE 

Important areas in the LTE simulator

  • Offloading

The following steps are included in a network for an effective offloading process.

Step 1: Offloading request from the SDN controller to SDN Wi-Fi

Step 2: Attaching request from the SDN Wi-Fi to the UE 

Step 3: Attaching response from the UE to the SDN Wi-Fi

Step 4: Offloading response from the SDN Wi-Fi to the SDN controller

Step 5: Allocating IP address among SDN Wi-Fi and UE 

Step 6: SDN controller handover the session to the Wi-Fi network 

Step 7: SDN controller terminated the request of the eNodeB

  • Scheduling 

In the downlink scheduling process in the broadband LTE networks generate the data from the media server to transfer to the wireless buffer to the base station and simultaneously, the user request on the data will be sent to the same base station. It then schedules the data to allocate the users respectively.

  • Secure data transmission

In this area, the UE requests the LTE network service by using its allotted IMSI number to the Mobility Management Entity (MME). It then transfers the request to the authentication center to verify the identity of the UE in order to confirm the network service. The authentication message is then stored in the HSS and it sends the message to the UE to activate the LTE service. Along with the major areas, we provide you the important networking process of the LTE simulator.

Major process in LTE simulator

The LTE network enables the user with a high speed of networking and browsing, particularly in mobile networks. It is based on the technologies of UMTS / HSPA and GSM / EDGE. The LTE network can simplify the core to provide higher speed and induced capacity by utilizing various interfaces. 

In the data transmission process of the LTE network, the UE requests the eNodeB by the user interface, to the Mobility Management Entity (MME), the request then passing through the Serving Gateway and the PDN gateway. Here, n sends the user request to the respective IP networks, and the request will be replied to by the server in the form of network service. Besides the major processes, we provide you the significant steps of the LTE network.

Important steps in LTE simulator

To render the simulating results of the average throughputs and the average SINR tables, the channel codingHARQ simulator with the inputs of channel coding rate, and the resource allocation have to be implemented to run the simulation process. Those elements are got from the output results in terms of each LLR transmitted in bit /average SINR from the MIMO-OFDM physical channel simulator with the help of the parameters like MIMO scheme and correlation, bandwidth, and modulationapplied in the LTE link-level simulator.

The above-mentioned steps are performed under the link-level simulation process. We displayed it because; it is the major networking service we are all using with the LTE network. In addition to the networking steps, we provide you the routing protocols of the LTE simulator

Our finest routing LTE protocols

ZHLS (Zone-Based Hierarchical Link State Routing Protocol): Similar to cellular networks, the entire network will be separated into non-overlapping zones in ZHLS. Each node 

familiar with the node connectivity of its own sector, which does not have any cluster head in the network. There are two levels for routing: 

  • Node level  
  • Global zone level.  
  • Fisheye State Routing (FSR): It uses the fisheye network structure, which decreases the amount of traffic to transfer the updated messages that do not contain information about all nodes but the updated data of neighboring nodes.
  • Order One Network Protocol (OONP): It is a computer algorithm communication to send messages among digital radio in a mesh network in a sensibly efficient path. It was considered and endorsed as functioning with wireless mesh networks.  

There are many protocols available in the LTE simulation but the above-mentioned protocols are widely used for our research and experimental purpose. That’s the reason for the high lightening. In addition to the important protocols, we get you to the core purpose, i.e. our suggestion on the research titles as displayed below.
