What is event in WSN?

Threshold based detection is a simple way events may be detected through the use of various parameters that can hint as to whether an event has occurred or not. Data collected at a sensor node, also called the data-event, is analyzed to see if it has reached a certain threshold point to be considered an event.

What is Event mobility in WSN?

In this paper, we present an energy efficient and event driven mobility model (E3DM) where mobile sensors inform each other about a static event and adjust their route to reach to the nearest point of that event. Sensors exchange some useful information between themselves by packet transmissions.

What are the different 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 two types of network sensors?

There two types of sensor networks, wired and wireless. 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 is base station in WSN?

1. The base station is at the upper level of the hierarchical WSN. It provides the communication link between the sensor network and the end-user. It contains the antennas and other equipment needed to allow wireless communications devices to connect with the network.

Which type of communication is preferred in the WSN?

Through wireless sensor networks (WSN), we can acquire the various interesting event information around sensor nodes through multihop communications. In WSN, there are two types of applications, that is, event or query based.

Which model is an example of event mobility?

Example include Random waypoint model, Random walk and Random direction model.

What are the types of mobility of sensor node in a network?

We can distinguish three different kinds of mobility in WSNs: (i) mobility of the sensor nodes; (ii) mobility of the sink node(s); and (iii) mobility of a monitored event/object. The first kind of mobility occurs when at least part of the sensor nodes is mobile.

What is WSN and its applications?

Currently, WSN (Wireless Sensor Network) is the most standard services employed in commercial and industrial applications, because of its technical development in a processor, communication, and low-power usage of embedded computing devices.

What are the features of wireless sensor networks?

A wireless sensor network consists of many different components of which a sensor node is an important yet small part. The characteristics of a good wireless sensor network include power efficiency, scalability, responsiveness, reliability and mobility.

What is wireless sensor networks with example?

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 are the applications of wireless sensor networks?

Wireless Sensor Network Applications Sensor nodes are used for constant sensing, event ID, event detection & local control of actuators. The applications of wireless sensor networks mainly include health, military, environmental, home, & other commercial areas.

What is a wireless sensor network?

A wireless sensor network is used for a variety of important applications in remote monitoring and target tracking. Recently, sensors have been manufactured to be smaller, cheaper, more intelligent, and equipped and interfaced wirelessly within a network for communication purposes.

What are the design issues in different types of wireless sensor networks?

The design issues in different types of wireless sensor networks mainly include The topology issues of wireless sensor networks include the following. The major issues of a wireless sensor network include the following. These issues mainly affect the design and performance of the WSN.

Why wireless sensor networks are important for the fire brigade?

The early detection is crucial for a successful action of the firefighters; thanks to Wireless Sensor Networks, the fire brigade will be able to know when a fire is started and how it is spreading.

Can wireless sensor networks prevent natural disasters like floods?

Wireless sensor networks can be effective in preventing adverse consequences of natural disasters, like floods. Wireless nodes have been deployed successfully in rivers, where changes in water levels must be monitored in real time.
