Get Ezwsn: Experimenting With Wireless Sensor Networks Using The ... - Cnx

In underwater sensor network issues and challenges like reliability and efficient utilization of acoustic communication link, optimal packet size selection for communication, power consumption, distributed localization, environmental effects, media access control, and network routing protocol still need to address.

The most popular communication protocols for WSNs are Wi-Fi, Bluetooth, and ZigBee. Wi-Fi is excellent for data exchange and is ideal where the power supply is not a problem, like in household devices.

The localization issue is important where there is an uncertainty about some positioning. If the sensor network is used for monitoring the temperature in a building, it is likely that we can know the exact position of each node.

Wireless Sensor Networks Wireless sensor nodes communicate via their radio modules. Two nodes are directly connected if they can transmit/receive data to/from each other. A sensor communication model (or a transmission model) is a mathematical model that quantifies the direct connectivity between sensor nodes.

Example: Meteorological stations use wireless sensor networks (WSNs) to collect data on temperature, humidity, and air pressure in various areas. This aids in precise weather prediction and accurate climate change research.

Wireless sensor network (WSN) is actually the sensor used to monitor physical conditions. Its typical applications include home health care or assisted living, environmental conditions, and military surveillance.

Abstract: Mobile wireless sensor network (MWSN) technology is a fundamental element of the Internet of Things (IoT) in which hundreds to thousands of sensor nodes (SNs) are connected via wireless channels capable of providing a digital interface to real-life objects.

The coverage problem is one of the fundamental problems in WSNs as it has a direct impact on the sensors energy consump- tion and the network lifetime [5]. The coverage problem can generally refer to how to monitor the network field effectively.

Wireless Sensor Networks A WSN consists of spatially distributed sensors, and one or more sink nodes (also called base stations). Sensors monitor, in real-time, physical conditions, such as temperature, vibration, or motion, and produce sensory data. A sensor node could behave both as data originator and data router.
