Wireless Sensor Networks (WSNs)

Powerful Essays
The range of wireless networking technologies is extended to cover voice networks and general data, which allows users to transmit different types of data through wireless connections over long distances, besides covering the techniques of infrared light and radio frequency optimal for short-range wireless communications. And with the popularity of laptops, hand phones, handheld computers, PDAs (PDA), pen-based computer, GPS devices, and post-pc era. Intelligent electronics devices that depend on wireless networking technologies have become cheaper, more distributed, more widespread in daily life, For example, users can use their hand phone to access their e-mail. As for travelers to use laptops and connect to the Internet through base stations installed at airports, railway stations, and other public places. Even In the home, users can connect devices to synchronization data and file transfer. From this point of view, the appearance of wireless networks such as wireless sensor networks (WSNs) and mobile Ad hoc networks (MANET) can be considered as the newest trend of Moore's Law to the smallness and ubiquity of computing devices. An overview on these two types of wireless networks (WSNs) and (MANET) and their use, will enable us to make comparison between them.

Wireless Sensor Networks (WSNs)
Wireless Sensor Networks (WSNs) is a collection of sensors that are used in the transmission or follow-up specific physical or chemical phenomenon such as heat, humidity, vibration, light, pressure, etc. and then transfer the information regarding to this phenomenon wirelessly to the processing center data to take advantage of them without the need for the presence of the human in the phenomenon place.
Typically, the wireless s...

... wireless technology applications, and it is likely to spirited to wetness more deployment in the few next years, as they mainly deal with unknown and untested environments and provide reliable monitoring and analysis for them.
Both (MANETs) and (WSNs) are ad hoc networks, with a limit in or no mobility in (WSNs). And none of them is substitutional for the other. And they have many differences as well as many similarities.
They offer more expedient means of communication, where infrastructure less networks can change a lot of applications that involved in military strategy, environment monitoring, information transfer, and home security. This idea can start a wave of wireless communication that world has not seen yet. And the independent mobile users will be needed to deploy rapidly to overcome the fact of decentralized connectivity and infrastructure less networks.
