Hi all,
I try to propose possible contribute to edgent project. In mobile edge cloud
computing, edge devices, such as the 3G/4G base station, wifi router, sensor
and mobile phone and so on, have the capability of computing and storage like
a computer. Particularly, edge servers on base station, wifi router have
powerful computing and storage. I think such edge devices can be used for more
useful edge application if edgent is extended.
In my knowledge, several replicas from edge devices (such as mobile phone,
sensor or wifi router and so on) may be stored in storage systems of different
locations, it may be valuable and useful that these replicas can be merged
together for some applications based on data consistency.
A simple or naïve scenario for my idea: there is a grand corn field
installed with 9 temperature wireless sensors being far away from themselves in
a farm, so one sensor only send its data to its local wifi router with
capability of computing and storage (I mean wifi router is also edge device).
How to detect high temperature event for corn growing? It is not reasonable to
make decision on a high temperature event if it only depends on the event from
only one sensor’s data. If every wifi router can merge the received sensor
event into a full consistent replica and populate this replica among these
routers, a good decision is made for corn grower. To do so, some components,
such as logical data model for mapping physical data, and other tools, are
needed for edgent. Therefore, application developer can code more useful and
advanced mobile cloud edge applications.
Addtionally, if we consider mobility of user and portable device,
picture data from mobile phone may be partially uploaded/downloaded to/from
edge server 1, remaining data are uploaded/downloaded to edge server2. It will
save mobile device’s energy and reduce low delay if the full data based on
logical data model (support data consistency) can be implemented by edge
servers on different locations for such edgent application.
It is my initial idea for code of edgent. Any comments welcome. Thanks.
