In order to obtain the required accuracy of measurement information, usually measured in the desired area, the layout of many sensor nodes, some even up to hundreds of thousands, say in the virgin forest fire and ecological conditions for detecting sensor network , a large number of sensor nodes, the distance between nodes is short, so that the information obtained can be more authenticity, improve the detection accuracy of information, so as not to cause damage to the individual sensor nodes detect the impact of finishing, redundancy enhanced, and reduced monitoring blind, which is monitored using the sensor network advantages. Usually, we press the function of these sensor networks into self-organizing network, dynamic network, a reliable network and application-related network. Below is a brief introduction: 
Care sensor network self-organizing network differences. Only by allowing the system closer to the application, in order to make the most efficient target system. For each specific application to study the sensor network technology, which is different from the traditional sensor network design salient features of the network. 
Each sensor networks have effectively qualified with the above features, so as to ensure the authenticity and reliability of the data obtained in the application process, to observe changes in the operation of the sensor nodes replenish node failure.
