Sensors usually depends on the environment power supply
for example Heat or vibration or sunlight
Are there units equipped supply Energy ( Wireless or Wire ) Is it possible that support power between neighboring sensors provide(can sensor depend on another sensor to supply its power ) to prolong the lifetime of wireless sensor networks.
Motivation to question in some proposals
broadband piezoelectric energy harvesting technology for sustaining the operation of wireless sensor network nodes.
Thus the attacker sends the device or have the ability to reduce energy in the sensors and thus network stopped(died)
If this thing is possible What are practical scientific experiments in this area ?
power supply means, you need to either transmit or receive which is only possible when you awake. for me other neighbours or to reduce the energy consumption or to increase the network life, you have to stochastically make your network nodes awakeup/sleep time more sophisticated or may be you can look some other protocols like speed, leach and their modifications
We have experimented couple of piezo-electric materials to harness electrical energy and in some instances we were able to store a very limited amount of power to our battery banks. The efficiency of such systems are very low and it greatly depends upon the node location in order to harness electrical power out of it.
Now, when it comes to Wireless sensor networks, the dynamics changes completely. We normally see two deployment scenarios
Now, considering the wireless sensing domain where we ought to use piezo-electric materials to generate power, one of the primarily needed passive devices would be a miniature battery source that could save and then deliver power to the nodes.
with my personal experience in wireless sensor networks, I believe solar could appear as a major contender in appearing as a secondary power source but piezo-electrics doesn't seem to fit well in WSN regime.
I have gone through couple of research articles regarding your scenario, we could look into that but I solely believe these are experimental works and may never see the daylight.

Thank you Muhammad Nasir Khan
I know To save energy, some location based schemes demand that nodes should go to sleep if there is no activity.
but my question Are there Sensors depend on another (Neighbors) in WSN for power supply ? in case idle time but for example wireless power supply in one node provide power to another can these technique happened not depend on sleep and awake mode .?

Thank You Omer Ali
but my question in case absence of environmental factors such as the sun and the other, only from the sensor to another .

You can forecast all type of scenarios. With technology advance, it is possible that a sensor node would be able to recharge another neighboring sensor of equivalent nature (power sharing). There are many research articles about mobile wireless charger. This charger can be seen as a simple mobile wireless node.
For these reasons, we proposed to extend IEEE 802.15.4 standard to consider all these possible scenarios :

Hope it helps.

Experimentallay, there's just one company in the world which have made a WSN system which is deployet in forest and frontier, the battery lifetime is 377 days, so after lifedead you can change the battery or delete the system from your networks,
I think the most issue in WSN, is hwo we can deploy WSN sensor algorithm for optimization in real time system,
