Abstract :
In this paper, we present an efficient data centric storage method for wireless sensor networks with increased resiliency for single node failures as well as clustered node failures. We introduce multiple hashing to provide various resiliency levels for different event types, based on the event´s criticality level. We also present a geometric area concept and node awareness inside the geometric shape to make our system independent of underlying routing. We present the two parts of routing from source to destination and shown our performance results.
