    Implementation of selected key performance indicators for enhanced rice production in a remote geo-location using wireless sensor network
    (Federal University of Technology, Owerri, 2023-02) Oyigbo, Uchechukwu Moses
    This study was conducted to implement selected key performance indicators (KPIs) for enhanced rice production by addressing five major challenges that face rice farmers especially in Nigeria which include non-availability of water/rain for year-round cultivation, disproportionate application of fertilizer, weed control/prevention, pest/disease control, and rodents and birds invasion. In order to achieve this, a Zigbee-based Enhanced Wireless Sensor Network (eWSN) was used to model various network scenarios to demonstrate data sensing of different environmental variables in a given farm land. This was achieved by varying network devices at different scenarios using OPNET simulator and understudying the network performances. Each new set of network devices are integrated to a Zigbee Coordinator (ZC) which assigns an address to its members and forms a personal area network (PAN), thus representing data sensing of a particular environmental variable. In all, three different scenarios were designed and simulated. Each of the temperature and humidity, motion and soil nutrient sensors generated about 29bps of traffic. At the Coordinators, steady stream of traffic was received. The temperature and humidity Coordinators, received a traffic of 64bps each, while the soil nutrient Coordinator received data traffic of 96bps. The result of the design showed effective communication between different network components and further gave insight into how WSN could be used to monitor a number of different environmental variables on a farm field simultaneously, yet co-operatively. By implementing the KPIs, the result equally showed an estimated yield increase from 2.2 to 8.7 metric ton per hectare of a rice farm.
