In an ordinary wireless network there are hubs set up specifically for connecting the wireless devices to the larger (wired) network. In a cooperative network, a device that can't reach a hub might talk to another device that can, and the second device would pass along the network traffic.
It's similar to one cell phone that can't reach a cell tower talking directly to another cell phone and letting that other cell phone connect it to the tower. (cell phones don't actually do this)

Definition of wireless sensor network in wikipedia?
Difference between wireless network and wireless sensor network?
Are sensor networks and wireless sensor networks the same thing?
The difference is a sensor network may be connected using wires or wirelessly, a wireless sensor network is always connected wirelessly.
What are the key design challenges of wireless sensor network?
the wireless sensor network will penetrate exhilarated interfaces in the area of tight penetration ability
What is the Conclusion of wireless sensor network?
The purpose of a wireless network sensor is to monitor environmental changes. It monitors things such as temperature, sound and pressure.
What do you mean by wireless sensor network?
sensor which is used know about the environmental condition
What is heterogeneous wireless sensor network?
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 .
What is a wireless sensor?
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.
Which protocol used in wireless sensor network?
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.
Why routing is required in wireless sensor networks?
Since, wireless sensor networks (WSNs) might differ depending on the application and network architecture. Moreover, nodes are dynamically deployed. Hence, data transmission through these types of nodes need a perfect route selection where nodes should remain active. So, routing is necessary for WSN.
What do wireless sensor networks monitor?
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.
What are the implementations of human area network?
The human area network is implemented for wireless body area networks. It is embedded inside the body, as an implant, used as sensor devices.
What is mobile sinks?
It is the link between mobile devices and sometime it act as an interfaces in WSN(Wireless Sensor Network). Regards Vijayakumar, Tirunelveli
