Abstract: The adoption of mobile technology in the agriculture sector can lead to benefits such as high productivity, improvement in mechanisation, increment in revenue, and timely information accessibility by farmers. The problem, however, is that mobile devices communicate over wireless mediums that can be unreliable; and when data states are kept on distributed nodes, inconsistencies can arise due to inefficiencies in the flow propagation of the updated agronomic data. This work describes a new key-value storage synchronisation workflow using exact set reconciliation and bloom filters. The proposed flow algorithm with its two-phase architect, with the first one being approximate synchronisation and the second one being exact synchronisation, provides better performance regarding bandwidth management. In addition, the usage of redundancy detection in the synchronisation mechanism makes it possible for the proposed algorithm to operate in a peer-to-peer environment, independent of any centralised server.
