What is Wireless Sensor Network PPT?
Introduction • A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.
What is wireless sensor networks?
A wireless sensor network (WSN) can be defined as a network of small embedded devices, called sensors, which communicate wirelessly following an ad hoc configuration.
What is Wireless Sensor Network PDF?
Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location.
What are the applications of wireless sensor networks?
Applications of WSN:
Surveillance and Monitoring for security, threat detection. Environmental temperature, humidity, and air pressure. Noise Level of the surrounding. Medical applications like patient monitoring.
What is an WSN and its characteristics?
WSNs measure environmental conditions like wind, humidity, temperature, pollution levels of sound, air and so on [2]. WSNs consist of spatially distributed and independent sensors to observe and monitor physical and environmental conditions.
What are the characteristics of WSN?
Characteristics
- Power consumption constraints for nodes using batteries or energy harvesting.
- Ability to cope with node failures (resilience)
- Some mobility of nodes (for highly mobile nodes see MWSNs)
- Heterogeneity of nodes.
- Homogeneity of nodes.
- Scalability to large scale of deployment.
What is WSN in simple words?
Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location or sink where …
What is WSN and its types?
WSN is a wireless network that consists of base stations and numbers of nodes (wireless sensors). These networks are used to monitor physical or environmental conditions like sound, pressure, temperature, and co-operatively pass data through the network to the main location as shown in the figure.
What are the types of wireless sensor networks?
Irrespective of the application, Wireless Sensor Networks in general can be classified into the following categories.
- Static and Mobile WSN.
- Deterministic and Nondeterministic WSN.
- Single Base Station and Multi Base Station WSN.
- Static Base Station and Mobile Base Station WSN.
- Single-hop and Multi-hop WSN.

What are the challenges of WSN?
Challenges in such WSN include high bandwidth demand, high energy consumption, quality of service (QoS) provisioning, data processing and compressing techniques, and cross-layer design. physical environment. Mobile nodes have the ability to sense, compute, and communicate like static nodes.
What are the basic components of sensor network?
The components of a sensor network include sensor nodes, sensors, the gateway, and a management node. The four topologies of sensor networks are point to point, star, tree, and mesh.
What are the components of WSN?
wireless sensor networks, the 4 important hardware units are; a processing unit, a transceiver unit, sensing units and a power unit.
