New Field Server Addition Method for Low-Price Rice Cultivation Management System

We are developing a rice cultivation management systems using a field server to reduce the workload of farmers. The feature of our field server is a reasonable price. In order to achieve the reasonable price, the accuracy of time synchronization is sacrificed. At present, it is possible to manage environmental data for crops and fields using sensors. However, there are some points to be improved in the current field server. The first is transmission scheduling in advance is had to set up. The second is that field servers cannot be added during the operation. This paper describes a method to notify all nodes of additional field server information and scheduling to solve the above problem. Simultaneous transmission type flooding method is described in detail. We will also report the experimental results. This protocol is robust for the rice cultivation management systems because the field server is stable. Therefore, it meets farmers' expectation to utilize a reasonable field server.
