Data Centric Storage in ZigBee Wireless Sensor Networks

Data Centric Storage is a recent paradigm that results more efficient than other storage techniques (such as local or external storage) in Wireless Sensor Networks (WSN). In this paper, the authors consider the use of this storage paradigm in WSN based on the ZigBee standard. In particular they propose a novel protocol (Z-DaSt) that exploits the routing and addressing features of ZigBee (that are based on routing trees) to distribute data to the sensors. The protocol also features Quality of Service in the storage of data by enabling the user to specify the amount of redundancy to be used in the storage of each datum.
