Wireless Network
Limitation on number of nodes
Comparatively more resources
Nodes can be mobile
May be battery operated. But
recharging is possible.
Main goal is to provide the service
Wireless sensor networks
Hundreds of thousands of nodes
Nodes integrate sensors, processors,
transceivers with limited resources
Nodes are generally stationary after
deployment
Each node depends on small low
capacity battery as energy source,
and cannot expect replacement
The main goal is to prolong the
lifetime of the network
The main difference is the severe resource contraints in sensor networks in terms of power, memory capacity ... etc.
God knows only
Difference between wireless network and wireless sensor network?
The difference is a sensor network may be connected using wires or wirelessly, a wireless sensor network is always connected wirelessly.
the wireless sensor network will penetrate exhilarated interfaces in the area of tight penetration ability
The purpose of a wireless network sensor is to monitor environmental changes. It monitors things such as temperature, sound and pressure.
sensor which is used know about the environmental condition
It is the link between mobile devices and sometime it act as an interfaces in WSN(Wireless Sensor Network). Regards Vijayakumar, Tirunelveli
A heterogeneous wireless sensor network(HWSN) is the network of sensors having wireless link with dissimilar communication range, sensing range or those sensors may be employed in numerous applications. In a distributed HWSN, different parts of HWSN may adapt different network configurations. The answer an be also include energy as basis for defining a network as heterogeneous , If wireless sensor network has 2 kinds of nodes , one type has x times more energy it can be called 2 level heterogeneous WSN and so on .
A Wireless sensor network, according to UbiBot, is a collection of devices that can exchange data gathered from a monitored field using wireless networks. The data is routed across numerous nodes and connects to other networks via a gateway, such as wireless Ethernet.
A wireless sensor network can use any suitable standard or non-standard protocol. Commonly used protocols include ZigBee (IEEE 802.15.4) and other members of the IEEE 802.15 protocol family.
Wireless sensor networks are capable of measuring certain aspects of a physical environment. For example, there are sensors available the measure temperature, pressure, and more.
The human area network is implemented for wireless body area networks. It is embedded inside the body, as an implant, used as sensor devices.
