Bluetooth Simulator (Performance Evaluation)

What is meant by Bluetooth simulator? In recent times, we are sharing information from one device to another via Bluetooth technology. And we are known what Bluetooth is and what function Bluetooth does give.

“In this article, we will see about the entire concept of Bluetooth Simulator and its modules and what are basic functioning in BT-Sim and its requirements”

Bluetooth simulator is a software emulator of Bluetooth hardware. It is a program that interacts directly with other Bluetooth hardware like a serial dongle. In BT-Sim, we can communicate redirect to this Bluetooth. BT-simulator is also referred to as the real hardware or testbed. 

What is the reason to write BT-Sim in java?

It has a lot of reasons to write the code in Java. There is,

• Java programs are portable, easy to install, and they can be downloaded using jar-file of a BT-Sim and double click on the jar-files.
• Java is the best and simple for building a BT-Simulator because it minimizes the development effort.
• And, it does not provide the different binaries and does not need to check their performance on different platforms.

 Java is an object-oriented programming language and it is platform-independent so we can build java in multiple operating systems. And another main reason for choosing java is it does not need to compile by us. It is automatically compiled by itself. These, are some basic reasons why BT-Sim writes in java. Then we will discuss the use of BT-Sim in real hardware.

Use of BT-Sim

There are many reasons to choose a Bluetooth Simulator,

• It is possible to test in software development is automatic.
• Easy to test a large number of Bluetooth devices at a time.
• Buying the additional hardware is unnecessary.
• Extending the Bluetooth features to the simulator is not supported by the currently available hardware.
• Communication is intercepted when we use simulators.
• It is used to connect multiple systems into one device. So it gives easy to access.

These are some use of BT-Sim. We have experts who are familiar with this kind of project and they are developing and developing projects on various topics. And we give the best and accurate solution for your queries. Coming to the article, then we will see about some basic functioning in Bluetooth simulator.

Basic functions of BT-Sim:

            Microchip or Transceivers is an essential component of Bluetooth. The frequency of transmitting and receiving is 2.4GHZ. It has canals with a range of 64Kbits / s of voice. 

• The maximum range of connection is 10 meters and when we use an amplifier the connection range is going to until 100 meters and it involves distortion.
• Every Bluetooth device is based on standard IEEE 802.11 for LAN wireless and each device has 48bits of unique direction.
• Point to point or multipoint topology can be used. Connecting all devices has a similar opportunity of access and in that similar connection one device is considered as a master device and others considered as a slave.

Until we are studying what Bluetooth simulator is and why we write BT-Sim in java and use of Bluetooth and its functioning and which are the IEEE standards can be used in BT-Sim and also transmitting frequency of Bluetooth. The next topic we will see about the platform of Bluetooth. 

BTnode Platform

           Bluetooth is a technology embedded in the node for communication and connecting the platform based on a microcontroller and a Bluetooth radio. Bluetooth nodes are used to give the platforms for mobile and also sensors for WSN and MANET. Recently, Bluetooth nodes are used for different purposes as follows, 

• Smart-Its
• NCCR MICS

Smart-Its:

• Smart-Its – Smart-scale embedded device is a technology for testing and building computing scenarios and it is useful to know the context-awareness of information and collection. 
• Projects in “smart-Its” are in an extensive idea of calculation in the embedded world and object to enlarge their awareness, calculation, sensing, and communication in everyday

• NCCR MICS:
  • This kind of NCCR MICS is considering all the problems in Wireless Sensor Network to understand their full possibility.
  • Creating applications and developing platforms and creating new start-ups is useful from the study of public finance principles and accounting.

The above two projects are developed recently based on Bluetooth nodes. And we have more project ideas based on Bluetooth simulators and other technology projects also. Then we know about NS2 and discuss it with some Bluetooth modules.

 NS2: In this part, we deal with NS, It is the next level of Bluetooth, and refer to the following        

points, 

• NS is an extended version of Bluetooth and it gives full support for multicasting protocols for the wired network and wireless network, Simulation of Transmission Control Protocol and routing.
• On other hand, NS is an event target simulator for networking research purposes. NS2 needs some resources it is listed below, 
  • Basics of NS:
  • Language : C++
  • Tool: OTCL for providing a simulation interface.
    • It is the object-oriented structure of TCL.
    • NS program simulates the network topology by writing the script of OTCL with some particular parameters.

Then, we know about some software modules of Bluetooth and the use of those kinds of modules and protocols.

1) University of Cincinnati Bluetooth (UCBT): 

                It is defined as simulating the Bluetooth network operations with more details. It is working based on the NS2 Bluetooth network module.

• A lot of baseband operations for example BNEP, L2CAP, and LMP used to simulate in UCBT with the following specification,
• Multi-slot packet type negotiation
• Frequency hopping scheme
• Role switch
• SCO voice connection
• Device discovery
• Hold, Sniff, and park modes management
• Connection setup and so on.

The group of 8 Bluetooth devices can be connected it is said to be a piconet. And, more piconets are connected using bridge nodes. This kind of connection or large network is known as a scatter net.

In the above section, we discuss one of the network models in Bluetooth and the following modules also is a type of network module.

• BlueHoc: Everyone can access the BlueHoc because it is an open-source Bluetooth Technology and it connects the baseband to the link layers.
  • BlueHoc is used as to platform for improving performance.
  • In an indoor wireless canal, it can be capable to connect an ad-hoc environment with more types of Bluetooth devices.
  • It gives paging protocols and performance of a particular Bluetooth device.
  • TCP/IP protocol is used in BlueHoc module.

These are some basic points for BlueHoc and the next module is Blueware.

• Blueware: This is an extension of BlueHoc software module. To, implement the Blueware there is re-design and re-write from the BlueHoc original code. And it contains an implementation of Bluetooth Simulator based on specifications of Bluetooth and scheduling algorithm and scatters net formation.

• License: IBM Public License, General Public License.
• Protocols: TSF, LCS (Link Scheduling Algorithm).
• Use of Blueware: Easy to interface            

 The above UCBT, BlueHoc, and Blueware give more knowledge about Bluetooth and BT-Sim. Not only these three software modules our experts know all the Bluetooth software modules and other technologies Then, but we will also go to know what the basic requirements are and which kind of operating system is supported for Bluetooth.

Basic requirements of BT-Sim:

In this section, basic requirements of Bluetooth simulators is given below,

• Language: Java
• Tool: JDK (Java Development Kit)
• Environment: Apache Ant(for open source and library)
• Port number: 7007(‘localhost:7007’)
• Other: Palm OS simulator.
• Supported OS: Windows, Mac, Linux

 Right now, we will cover the entire concept of the Bluetooth Simulator. We are developing and developing projects based on Bluetooth hardware and other technologies. We provide you with better knowledge of all wireless communication technologies. For further more details contact us.
