Typical sensor nodes are wireless nodes with limited storage and computational power. Furthermore they are prone to ―failure‖ by going out of wireless range, interference running out of battery etc. They can be deployed in isolated or dangerous areas to monitor objects, temperatures, etc. or to detect fires, floods, or other incidents. There has been extensive research on sensor networks to improve their utility and efficiency. The sensor and storage nodes are distributed randomly in some region and cannot maintain routing tables or shared knowledge of network topology. Some nodes might disappear from the network due to failure or battery depletion. A distributed data collection algorithm to accurately store and forward information obtained by wireless sensor networks is proposed. The proposed algorithm does not depend on the sensor network topology or geographic locations of sensor nodes, but rather makes use of uniformly distributed storage nodes. Analytical and simulation results for this algorithm show that, with high probability, the data disseminated by the sensor nodes can be precisely collected by querying any small set of storage nodes.

Introduction Wireless communication is the transfer of information over a distance without the use of electrical conductors or cables. The distances involved may be short or long. Wireless operations permits services, such as long-range communications, that are impossible with the use of wires. Information is transferred in this manner over both short and long distances. Wireless sensor networks (WSNs) often consist of small devices (nodes) with limited processing ability, bandwidth and power. They can be deployed in isolated or dangerous areas to monitor objects, temperatures, etc. or to detect fires, floods, or other incidents. [16].There has been extensive research on sensor networks to improve their utility and efficiency. For WSN applications, the data in the sensors are often streamed to a control centre (called sink). This process is called data collection [1]
