The data centric Wireless sensor network (WSN) is firmly emerging technology, which addresses the solution to a un tethered environment applications. It has the ability to observe the target and makes the link to outside world. WSN remotely collects the huge volume of data and communicating the signal from the Sink. It provides measurable response to the changes in the environment. Rushing of the enormous data directs to jamming in the network, which affects large portions of the network. Many of the existing schemes focused on link level congestion. We propose open stream scheme, which discusses the congestion free environment in node level congestion. It maintains stream called open stream. Open stream is followed, when abnormal changes occurred in the environment and rest is for normal data flow. Aspire is, the node should be able to identify which is to be forwarded and ignored and it should not drop the real time information because it cannot be replaced by recent information. Our scheme is not spending too much of energy and resources. It annotates that which real time information should be broadcasted towards the sink properly, since node deployment is in large scale environment. Further our scheme is concentrating on congestion free and less energy consumption for critical environmental applications.
