This paper introduces a new data transport architecture and protocol for storage that is implemented on wireless devices and that can be accessed through a short-range wireless access technology such as Bluetooth or 802.11. We call the protocol WATA (Wireless ATA), as its architecture is similar to current ATA and ATA-based technologies. In this paper, we give basic technical details of the protocol and discuss its main advantages and disadvantages over the current protocols, and talk about our decisions to implement a prototype system to see an actual implementation of the architecture.
