Abstract
According to one embodiment, a storage device includes a wireless communication circuit, a storage, and a controller circuit. The wireless communication circuit is configured to connect to an external first device by wireless communication. The storage has a storage region. The controller circuit is configured to correct first information on the basis of a first capacity which is a free space of the storage region of the storage. The first information is numerical information indicating quality of the wireless communication with the first device. The controller circuit obtains second information being the corrected first information.
Claims18
A storage device comprising:
- a wireless communication circuit configured to connect to an external first device by wireless communication;
- a storage having a storage region;
- and
- a controller circuit configured to control the storage and to correct first information being numerical information indicating quality of the wireless communication with the first device based on a first capacity which is a free space of the storage region of the storage to obtain second information being the corrected first information, wherein
- processing of correcting the first information includes processing of dividing the first information by an average value of the first capacity and a second capacity which is a free space of a storage region of a storage provided in the first device.
A storage system comprising a storage network including a plurality of storage devices connected to each other by wireless communication,
- wherein each of the plurality of storage devices includes a storage having a storage region and is configured to:
- control the storage included in each of the plurality of storage devices itself;
- correct first information being numerical information indicating quality of the wireless communication based on a free space of the storage region of each of the plurality of storage devices itself;
- and
- determine a path of the wireless communication within the storage network based on second information that is the corrected first information, wherein
- processing of correcting the first information includes processing of dividing each of the first information of two storage devices that are wirelessly connected to each other among the plurality of storage devices by an average value of each of a free space of the storage region of the two storage devices.
A method of wireless communication between storage devices, each of the storage devices having a wireless communication function and comprising a storage, each of the storage devices being configured to control the storage included in each of the storage devices itself, the method comprising:
- by a storage device among the storage devices, correcting first information being numerical information indicating quality of wireless communication between a first device connected by wireless communication to the storage device and the storage device based on first capacity being a free space of a storage region of the storage included in the storage device itself;
- and
- obtaining second information being the corrected first information, wherein
- the correcting the first information includes processing of dividing the first information by an average value of the first capacity and a second capacity which is a free space of a storage region of a storage provided in the first device.
A method of wireless communication in a storage network including storage devices, each of the storage devices having a wireless communication function and comprising a storage, each of the storage devices being configured to control the storage included in each of the storage devices itself, the method comprising:
- by a storage device among the storage devices, correcting first information being numerical information indicating quality of wireless communication based on a free space of a storage region of the storage included in the storage device itself;
- and
- determining a path of the wireless communication within the storage network based on second information being the corrected first information, wherein
- the correcting the first information includes processing of dividing each of the first information of two storage devices that are wirelessly connected to each other among the plurality of storage devices by an average value of each of a free space of the storage region of the two storage devices.
