TCP / IP Protocol

TCP (Transmission Control Protocol) is a set of rules that are available for connecting the Internet to various Internet devices. We can say that this is a communication protocol that has a host that has access to the Internet. This is a good topic for a M.Tech dissertation in networking. If you choose this network theme for research, here are some basic introductions.

TCP / IP transmits end-to-end data transferring devices with certain features, such as addressing, mapping, and acknowledgment. TCP / IP is a combination of two protocols. TCP controls the messages by splitting them into packets. The IP controls the transmission of these packets from the sender to the receiver.

TCP / IP Protocol Layers

The following four TCP / IP layers:

Application Layer

Layer

Internet Layer

Physical Layer

TCP / IP communication mode. The application works as follows:

The application layer consists of various data exchange applications such as HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol) protocols

between the host and the user. Use the UDP (User Datagram Protocol) protocol.

The Internet layer is responsible for transmitting packets over the network and uses an Internet Protocol (IP) for this purpose.

Physical layer provides interconnection between nodes.

Advantages of TCP / IP Protocol

Easy to change.

Compatible with all operating systems.

Can be scaled to determine the most appropriate route.

So this is a good topic for M.Tech dissertation and research. Students specializing in subject counseling can get help supervisors on this topic. You can also explore more details about the subject on the web.

NS2

Another good computer network theme for a M.Tech thesis for NS2. NS is the Network Simulator. It is an open-source, discrete event-based network simulator that is primarily used for research purposes and education. It helps you simulate routing protocols (IP, TCP, UDP, etc.). Creates a simulation environment for studying the network. The following steps are followed when creating the simulation environment:

Topology Definition

Model Development

Configuring Connection

Implementation

Analyze Problem

Visualize

Topologies, the network's behavior. Behavior is analyzed by tracking events. NS2 provides textual and animation-based simulations.

Advantages of NS2

Can support multiple protocols.

Graphically depicts network traffic.

You can support multiple algorithms for routing and queuing.

NS2 is a very good subject for a M.Tech dissertation on the computer network. It is not only theoretical knowledge, but also the practical experience of the network simulator tool. You can get a thesis from NS2 from an expert who has practical knowledge of how to use the tool.

MANET

MANET is a mobile ad hoc network and another good choice for a Thesis on M.Tech in networking. In MANET, nodes can be configured independently and are able to move freely in any direction and can often be linked to other devices. MANET was originally used for defense purposes. MANET is the challenge of weak signal strength, reliability, power consumption and other problems.

MANET Features

Each node is independent of nature, so each node acts as a host, as well as a router.

Based on the distributed nature of security and configuration operations.

The network is dynamic in nature, so every node can join and exit from the network at any time.

Network nodes are associated with less memory and power.

In MANET bandwidth is still fluctuating.

MANET creates a symmetric environment that each node has the same attributes as responsibilities and capabilities.

Blocks MANET Routes

There are certain obstacles on MANET Road that need to be overcome. Some of these:

Reliability of transmission is influenced by certain factors, such as data loss, interference, and clutter.

Transmission speed is limited to a certain range, but data rate is reduced.

Packet loss may occur during data transfer.

Frequent road sections.

Lack of firewall results in network security issues.

This is just MANET's presentation to give an overview of what is going on with this topic for M.Tech's thesis.

Network Security

Network Security is a set of rules that ensure the security of your organization or your personal network. You can choose this topic for M.Tech's thesis if you fully understand that data is being transferred over the network. Network security also includes the security of physical hardware. Network security in the software means that access to the network is allowed through id and password.

When a user tries to access the network, authenticity must be verified with times and passwords. This is to prevent malicious users from accessing the hacking motive of the network.

Types of Network Attacks

Active Attack – During this type of attack, the hacker tries to change the data while it is moved from one node to another.

Passive Attack – During this type of attack, an outsider monitors the organization's system to consistently find the vulnerable ports.

The following are some tools for network security:

Wireshark

Aircrack

Snort

BackTrack

Netcat

(practical + theoretical) Security

then select this topic for the M.Tech dissertation. In addition, a supervisor will be assisted by computer network experts.

Network Topologies

The network topology is the layout of physical and logical nodes. This is a light theme for the M.Tech thesis. Some Common Physical Topologies:

Bus – In the bus topology, each node is connected to the main cable for the bus, so each node is directly connected to each other node.

Star – In the star topology, each node connects to a central hub so that each node is indirectly related to each other.

Ring – In this topology, nodes form a closed loop so that adjacent nodes are in direct contact with each other.

Token Ring – The token ring topology protocol is used. A token is moved from one node to another. A node that wants to retrieve the data needs to get the token.

Network – In a network, each node is directly connected to each other node. It can be a full net or sub-network.

Fa – This is the linkage between bus topology and star topology.

Chain Daisy – In this topology, each node is linked to two other nodes, but does not form a closed loop like ring topology.

Hybrid – Combination of two or more topologies.

If I'm afraid of the complex subjects of M.Tech's thesis, this topic applies. Easy to understand and work. Just go for it.

IPv4 / IPv6

This is another important topic in computer networks and is a good choice for your thesis or project. Ipv4 is the fourth version of the Internet Protocol, while Ipv6 is the sixth version of the Internet Protocol.

IPv4 features

uses a 32-bit address.

The address should be separated by a decimal number.

The header contains a check amount.

Broadcast addresses are used to send data packets to other nodes.

In this protocol, Internet Protocol Security is optional.

Ipv6 features

uses a 128-bit address.

The title is hexadecimal, separated by two.

The header does not include a check amount.

Mediated titles are not used to send data packets.

The Internet Security Protocol is required.

It is a good area to study how data is transmitted over the Internet. You will learn IP datasets from Ipv4 and Ipv6. This can be selected by M.Tech as a thesis.

OSI model

OSI means open interconnection. This is another good topic for a M.Tech thesis in the computer network area. Provides a network framework for implementing protocols in layers. Seven Layers of the OSI Model:

1. Physical layer – This layer is responsible for transmitting digital data from source to target.

2nd Data Link Layer – This layer checks the data error with the MAC address. Transforms the bits into data frames.

3rd Network Layer – This layer checks whether the data have reached the destination or not by examining the source and target address.

4th Transport layer – This layer transmits data over the network using TCP protocol.

5th Session Layer – This layer handles events and queues. It supports multiple connections.

6th Presentation Layer – Provides encryption and decryption of syntax and overlay application layer.

7th Application layer – End-to-end user applications use protocols such as HTTP, FTP, SMTP.

It differs from the TCP / IP model. Your supervisor's supervisor comes from a computer network specialist.

WLAN

Wireless Local Area Network. This is another good choice for M.Tech's thesis in the computer network. This is a wireless distribution method that uses high frequency radio waves with a single access point to the Internet. In other words, wireless communication between two or more devices, allowing users to move in a limited range. Most common in homes or offices. The WLAN-connected component is the station. There are two types of stations – Access point

Customer

Access points are base stations that transmit and receive radio frequencies for wireless devices. Customers are mobile phones, laptops and desktops connected to the wireless network.

WLAN Operation Modes

There are two ways to operate WLAN:

Infrastructure – In Infrastructure mode, the base station acts as an access point and all nodes communicate at this point.

In ad hoc – Ad hoc mode, mobile devices directly transmit data with an equivalent method. There is no base station in it.

WLAN Benefits

Many devices are eligible.

Wireless LAN is easy to set up like installing cables on a wired network.

The wireless network is easier to access than a wired network.

WLAN Disadvantages

It is difficult to expand the network.

Faces security issues like hacking.

Interference is another problem with WLAN.

WLAN is another lighter topic for a M.Tech thesis. Used everywhere. Supervisors can get help from network specialists on this topic.

Encryption

Knowledge of data privacy. In the M.Tech thesis it is also easy to choose a topic in networking. The encryption protocol used for data transfer over the network has three main purposes:

Confidentiality

Integrity

Authentication

Encryption uses two methods to maintain data confidentiality:

Encryption – converts plain text into some other form, which is known as secret.

Decoding – In this technique, the converted text, that is, the encrypted text will be translated to the original text.

There are two cryptographic algorithms. In the symmetric key, both the sender and receiver use the same key for encryption and decryption.

In the asymmetric key, both users have a different key to encryption and decoding.

This is a familiar topic and very easy to understand. Take the thesis specialist from this area to get started on this topic. IEEE 802

IEEE is the Institute of Electrical Engineering and Electronics. The IEEE 802 is a very challenging and very good topic for the dissertation. IEEE 802 belongs to IEEE and deals with LAN (Local Area Network) and MAN (Metropolitan Area Network). Specifies the features and protocols of the physical layer of the data link layer and the OSI model. IEEE is divided into 22 additional sections that provide a broad range of services.

IEEE 802 splits the data link layer into two layers: Logical Link Layer (LLC)

Media Access Control (MAC)

You can choose any subfield as part of your project or thesis. This is a very good area to explore.

These were some of the topics of the M.Tech dissertation in computer networks. In addition, you can select any one for networking or project. You can explore these themes more.
