Introduction about MiXiM Simulator: In current days, network simulation performance evaluation is a challenging task and all types of networks performance are improved using QoS and SLA metrics. It is a time to gain knowledge about the specific simulator called as MiXiM. Let we start,
“This article provides you a piece of knowledge about MiXiM Simulator and the base model of simulator and simulation models, its components and so on”
MiXiM is abbreviated from mixed simulator. By using OMNeT++ simulation engine to construct a framework for mobile networks and the wireless and main reason for writing this program is to increase the wireless and mobile simulation. This kind of MiXiM simulator can be interconnected with several OMNeT++ frameworks.
Simulation of wireless communication systems must have the physical layer, radio channels, and perfect abstraction from the environment. Here we consider three base models for MiXiM. There are,
This is one of the base models used in MiXiM Simulator. This connection modeling is directly opposite to the wired network simulation and connecting more models it’s a highly challenging process in wireless network simulations.
The above content represents the MiXiM base model. Then we will go to the next model in this simulator that is the physical layer model, in this model we can get a clear idea about FEC and coding gain.
In this physical layer, we are using some functions for defining the throughput of a system and the bit rate of a system. Here, the functions are coding, decoding, and FEC (Forward Error Correction).
This kind of SNR-based model can be extended when the system is finding a bit in a single channel. This extended process can be done until the bit rate is calculated where is the place in which more channels are connected.
A Simulation takes place in a limited area and it is based on which objects are placed and which nodes are placed. Here wireless devices are considered as nodes and it already has a protocol stack with an isotropic radiator. It does not contain any other physical dimension. MiXiM Simulator has four strategies to avoid a border crossing and collision. There are,
Wireless channel models
The frequency and space of multi parallel radio channels are always possible by MiXiM channels. Here is an example for the space is a multi-antenna system and an example of the frequency is OFDM subcarrier terms.
The above four models are the base models for the MiXiM. Without this model the Simulation of MiXiM is difficult. So, this model is mandatory for constructing a MiXiM. Then we will go to the next topic which is Simulation modules in MiXiM. This is said to be a word utility module.
MiXim simulator is used to collect global parameters for example whether the world is in a cube or a plane and simulated area size is a playground. Mainly, the MiXiM takes the object for an environment.
Networks are built with more nodes. Different kinds of nodes are considered in MiXiM that nodes are also called terminal and Accesspoint of the network. These are the simulation modules in the MiXiM. We learn more basics from these modules and the characteristics of the objects also. Then we will discuss Component groups in the network.
Because of, well-developed infrastructure MiXiM gives detailed protocols and models. In this MiXiM Simulator, the basic components can be classified into five parts. There are,
These are the group of components in the MiXiM simulator. In this above content, we know some techniques like collision, reception and error handling and etc. Finally, we will see about the protocol library for the MiXiM.
In MiXiM simulation it is possible to change one model into another model. To add the functions and override the functions is used to a basic level of construction. Here, three types of protocol libraries are there. Then we will discuss each and every protocol separately.
Network Layer protocols: This protocol is used for multiple traffic constraints, for example, local neighborhood, Source to sink, and any to any, and it gives full support for simulation modules like data localization.
This Medium Access Control protocol is mainly designed for a decision-making purpose about communication between nodes in the network and also a low power sensor network. This protocol construct by TU Delft. In Mac protocol, there are two base classes for building a sensor network. There are,
Uses: Provide support for low power functions and sensor networks.
Uses: provide a decapsulation and encapsulation of packets.
There are some protocols used in the MiXiM simulator. So far, we are discussing the basics of the MiXiM, base models, simulation modules of this simulator, and protocols also. We hope this article is useful for you and we have more number of developing and developed a project based on these kinds of topic. Our expert has a wonderful knowledge with these kinds of projects also.
