Wireless sensor networks consist of small devices (nodes) with limited CPU, bandwidth, and power. They can be deployed in isolated, tragedy, and obscured fields to monitor objects, detect fires, temperature, flood, and other disaster incidents. They can also be used in areas difficult to reach or where it is danger for a human being to be involved. There has been extensive research work on sensor networks to improve their services, power, and operations. They have taken much attention recently due to their varieties of applications.
