Thesis and Research Topics in Computer Networking
Computer Networking is a field that deals with the creation of networks to connect different devices for communication. This field has evolved a lot in the recent times with better and faster communication networks. A simple network consists of a communicating device like computers, switches, and routers connected through wires or wireless signals. Client and server are an important part of the network. A client requests for service or information from a server. There are certain protocols laid down for the establishment, operation, and management of a network. There are various topics in computer networking which have a huge scope for research as well as for M.Tech thesis.
Here is the list of current topics in computer networking for thesis and research:
- Wireless Sensor Networks

Wireless ad hoc Networks
Wireless ad hoc Network or WANET is a type of wireless network and unlike wired networks, it does not depend upon the pre-existing infrastructure. In this network, each node takes part in routing and these nodes are free to move. Routing algorithms are used to forward data from one node to another in the network. The network is self-configurable and dynamic.
Routing in Wireless ad hoc Networks
There are three types of routing in wireless ad hoc Networks:
- Proactive Routing – Frequently distributes routing tables in the network by maintaining a new list of destinations and routes.

Wireless Local Area Network(WLAN)
Wireless Local Area Network or WLAN is a wireless network of two or more devices mainly used in homes, offices, schools. WLAN is based on IEEE 802.11 standard and is popular as Wi-Fi. There are two modes of operation of WLAN:
- Infrastructure mode
- Ad hoc mode
The coverage area of the network is limited to a few meters and has a single access point to the internet. The components of the wireless network are referred to as stations. The stations that provide wireless routing are known as access points while the other components such as laptops, smartphones are wireless clients in the network.
Applications of Wireless Local Area Network
WLAN has a number of applications from small home-based networks to large area networks. Various restaurants and hotels provide WLAN hotspots to access the internet. Its applications can also be found in homes, schools, colleges, and offices.
Network Security includes a set of policies and activities designed to protect the integrity of the network and its associated data. It aims to prevent any unauthorized access and misuse of the computer network and its resources. A valid username and password are provided to the users of the network. There are three principles of network security referred to as CIA:
- Confidentiality – To prevent any unauthorized access
- Integrity – To ensure that network assets are handled in an authorized manner
- Availability – To ensure that authorized users have proper access to the network
In order to ensure the safety of the network, a firewall is used to monitor the incoming and the outgoing traffic with a set of predefined security standards. In simple terms, it acts as the defense between the internal network and the external network and filters the traffic between these networks.
Types of Network Security
There are different types of network security such as:
- Application Security – This type of security protects the applications from the outside attack
- Email Security – Email security is vital to prevent any kind of security breach
- Wireless Security – To ensure the safety of the wireless networks
