Wireless Sensor Networks (WSNs) are an emerging class of wireless networks that are rapidly gaining popularity due to their wide range of military and civilian applications. A WSN consists of a set of interconnected tiny sensor nodes that communicate with each other and exchange information. These nodes gather environmental data such as pressure, humidity, temperature, or pollutants and transmit this information to a base station. By selecting thesis topics in WSN, students can explore its various components. This blog will cover ad-hoc networks, network topology, multihop networks, applications, challenges, and components of WSNs.
Here are some potential Thesis Topics in WSN:
Adhoc network:
An ad hoc network is spontaneously formed when devices communicate and connect. The word ad hoc is a Latin word that means "for this," implying improvised or impromptu.
Ad hoc networks are mainly wireless local area networks (WLANs). The devices directly communicate with each other instead of relying on access points or base stations as in wireless LANs for data transfer coordination. Each device participates in routing activity, by controlling the route using the routing algorithm and forwarding data to other devices through this route.
Network topology:
In a computer network, there are numerous ways via which different components are connected. Network topology is the way that specifies the structure and components that are connected. The arrangement of a network that consists of nodes and connecting lines through sender and receiver is termed Network Topology. The numerous network topologies such as bus topology, mesh topology, star topology, ring topology, point-to-point topology, tree topology, and hybrid topology.
Multi-hop network:
A wireless multi-hop network consists of multiple nodes that can connect directly with one another or extend their transmission range by acting as relay points and routers. Multi-hop communication has several advantages including spectrum reuse increase, traffic load balancing, interference reduction, radio coverage extension, and energy consumption reduction.
Applications of WSN:
The main applications of WSN are:
- Landslide detection
- The noise level of the surrounding
- Medical applications like patient monitoring
- Surveillance and monitoring for security, threat detection
- Internet of Things (IoT)
- Environment temperature, humidity, and air pressure
- Agriculture
Components of Wireless Sensor Network (WSN):
- Sensors: The sensor in WSN is used to represent the environmental variables for data acquisition. Electrical signals are converted from sensor signals.
- Radio Nodes:
It receives sensor data and transfers it to the WLAN access point. It includes a microcontroller, a transceiver, external memory, and a power supply. - WLAN Access Point:
It receives the data sent by the Radio nodes wirelessly, generally via the Internet. - Evaluation Software:
The data received by the WLAN Access Point is processed by a software known as Evaluation Software for presenting the report to the users for further processing, analysis, storage, and mining of the data.
Challenges of Wireless Sensor Network: There are several challenges including:
- Quality of Service
- Security Issue
- Energy Efficiency
- Network Throughput
- Performance
- Ability to cope with node failure
- Cross-layer optimization
- Scalability to large-scale deployment
