This page mainly focuses on NS3 Wireless Simulation Projects with technologies developments from a research perspective!!!

However, it is a forward-thinking technique; it has some limitations in real-world execution. Our resource team is proficient in both identifying and cracking technical issues of NS3 wireless simulation projects. If you are looking for the best guidance in solving your handpicked research problem, then we are ready to give appropriate solutions for your research challenges. For your awareness, here we have addressed the two primary encounters of wireless networks that the majority of scholars attempting to overcome.

Challenges of Wireless Network

• Mobility – Frequent random movements of the users / nodes
• Wireless – Transmission of data over wireless channel may leads to security threats

In network communication, the data are transmitted in the form of packets. That is, the data are divided into several small units called a packet. And, these packets are transmitted through different communication channels from source to destination. Here, the packet holds the following information.

Wireless Packet Information

• Packet – Create pointer for packet
• Expire Time -– Drop the packet once it expires
• Packet Type – Control or Information

Next, we can see the key characteristics of wireless links. These characteristics are more popular among research people where many of the research issues are framed from these characteristics. Our experts are ready to give you more information on other vital characteristics of Wireless Link.

Wireless Link Characteristics

• Multiple-Path Propagation
  • When the radio signal reaching nearer to destination, radio signal get reflected from object ground and create time variations
• Low Signal Strength
  • When the radio signal passes over the matters, it leads to loss of signal strength
• Inference Generated from Various Sources
  • When more network devices shares the same frequency bands, it has the possibility of interference occurrences

From the theoretical perspective of NS3 wireless simulation Projects, most of the network simulators are working well in single-channel protocols for network performance assessment. At the same time, those simulators facing challenges in multiple radio/channel networks. Since it needs more adjustments to acquire expected results.  

In general, the communication network study is based on both mathematical modeling and testing to attain the desired performance. In the past decades, analysis of mathematical function is a challenging issue, but now it is simplified through network simulation tools. It enables the developers to easily identify the real network performance and behavior. Also, it helps to study the working capabilities and efficiency of network protocols, techniques, algorithms, components, wireless topics for thesis etc. Overall, it is very useful in analyzing the protocol design, test network capacity, and performance in different scenarios.
