    "Ag-IT developments and sensor network applications in Taiwan"


    In Taiwan, the mission of developing information technology in agriculture includes enhancing farmers’ service functions, increasing government efficacy to master real time agricultural production and marketing information, establishing digital marketing and logistics channels, strengthening the performance of the agricultural production decision making system, and assisting farmers in improving their management efficiency. Sensor network (SN) technology plays an important role in helping the modern agricultural developments in Taiwan achieve this mission, through activities such as field monitoring, integration with automation systems, pest and disease control, etc.

    In this study, we present several SN application examples developed in Taiwan; a paddy field server (PFS) system was constructed and deployed in the paddy field to automatically collecting data through crop seasons. The relationships among fertilization, chlorophyll concentration, and leaf color can be established by using statistical analysis. Therefore, remotely monitoring leaf color can predict chlorophyll concentration as well as the fertilization used in the field to help farmer’s field management. The soil moisture variance (VWC) sensors of the PFS used in the paddy field can help inexperienced farmers and researchers study the irrigation stratagem from the good farmers who can grow high quality Japonica rice in a specific geographic area. An ecological Oriental Fruit Fly WSN monitoring system was developed and widely deployed in the island through GSM network to study the insect population density and migration habit. An expertizd precision farming system using SNs was developed to help distribute Lychee on fruit farms; it can remotely get advices in time according to the weather and their orchard conditions to grow the fruit and to make good profit. RFID and SN technology were developed to help dairy and deer farms’ with automated management. Further applications can integrate all automated equipments in the farm such as an online dairy cow mastitis detection system with WSN to achieve an automated, dynamic, intelligent management system development.

    "Micro-Mobile MPLS : Performance Analysis and Improvement" - Slides


    In this paper we propose the method to decrease the numbers of losing package while moving across the network by Received Signal Strength Indicator (RSSI) Technique using define appropriately signal strength between MN and FA. We use this technique to serve in Micro-Mobility MPLS for improvement sending packet. The simulation has improved the performance of Mobile MPLS by reducing losing package.

    "Natural Disaster Monitoring by SensorWeb Technology in Thailand" - Slides


    This abstract describes an effort to integrate space-borne sensing from MODIS (Terra and Aqua), ALI (EO-1) and in-situ sensing information, to improve the natural disaster monitoring efforts such as forest fire and flood monitoring in Thailand. Natural disaster is the major cause of the destruction of humans' civilization. It is inevitable. Forest fire and flood are major disaster events in Thailand year round. There is technology, called "SensorWeb" developed by NASA to provide supporting space based information, to provide additional decision support with higher resolution imageries and derived products e.g. fire burn severity by differenced normalized burn ration (dNBR) and surface water extent (SWE) maps. Both fire and flood sensorweb systems in Thailand were established in late 2010. Both systems were trigger by MODIS Terra/Aqua products and field observations. Both systems well supported Thailand?s forest fire and flood management in 2011. Moreover, in case of forest fire trigger, the system will be improving by using NPP-VIIRS fire products.

    "Satellite Field Integrator based on OGC Web Services to enhance GEO science study"


    The Satellite Field Integrator (SFI) system is based on various open standards of the Open Geospatial Consortium (OGC) Web Service specifications. It supports heterogeneous data formats in both remote sensing and sensor observation data, and has the scalability to handle the increasing number of datasets currently available. Furthermore its standard data sharing operations offers a robust, on-demand processing service to reduce the onerous tasks of data gathering, manipulating, and processing. The end-user can perform an analysis or retrieve final results with minimal effort by overcoming the need for the complex workflow, high skills requirement, and expensive facilities needed to operate with large and heterogeneous datasets though standard protocols in the current distributed web service architecture.

    Various applications have been developed to demonstrate the efficiency of integrating heterogeneous data source by using SFI framework. For example, the validation of the MODIS aerosol products (MOD08, the gridded atmospheric product) by ground based measurements using the sunphotometer (skyradiometer, Prede POM-02) installed at Phenological Eyes Network (PEN) sites in Japan. Furthermore, the web based framework system for studying a relationship between calculated Vegetation Index from MODIS satellite image surface reflectance (MOD09, atmospheric corrected product) and Gross Primary Production (GPP) field measurement at flux tower site in Thailand and Japan has been also developed. Not only the validation and tools for relationship study between ground based measurement and satellite observation are provided but also a web based framework for on-demand estimating air temperature from MODIS Land Surface Temperature (MOD11) with in-situ data collected from weather stations of Live E! sensor network in Japan is developed.

    The success of applications contributes to maximize data utilization and improve accuracy of information using high degree of accuracy and temporal measurement of field measurement data validating and gathering information that is scarcely obtained from direct satellite observation.

    "GeoSense: OGC compliant sensor web and modeling service for agriculture" - Slides


    Wireless Sensor Network (WSN) for agricultural applications has facilitated decision making for crop planning and management, particularly in precision agriculture aspects. With ever increasing agriculture-WSN interactions, there is a need for the standard sets of specifications and encodings to bring multiple sensor networks on common platform. The burgeoning cost-effective distributed sensing systems when brought together with interoperable capability can facilitate the agriculture community for better and uniform decision making.

    The Open Geospatial Consortium (OGC) through Sensor Web Enablement (SWE) has provided guidelines for semantic and syntactic standardization of sensor networks. As a part of Indo-Japan initiative ?GeoSense? (, where in two types of distributed sensing devices (mote-based AgriSens and wifi-based FieldServer) were used with Geo-ICT to develop a real to near-real-time decision support system for precision agriculture, an attempt has been made to implement the OGC SWE standardization through a Service Oriented Architecture (SOA) approach. Sensors in WSN are defined by the Sensor Model Language (SensorML) and Sensor Observation Service (SOS) client has been developed to visualize the sensor observations and measurements. SensorML process chains helped in online data processing for crop water requirements and availability in a systematic manner for both the sensing devices. The client also has an ability to operate in an interoperable manner with any other OGC standardized WSN system elsewhere. Also, through SOA, it is possible to design the real time monitoring and advisory system in agriculture and related domains for better decision making.

    This presentation will update on WSN initiatives in Malaysia over recent years. It shall highlight some of the Proof of Concept (POC) projects to showcase WSN applications in Precision Agriculture and indicate the benefits of the technology for the farmers. It shall also touch on initiatives in other sectors particularly on slope monitoring and critical infrastructure monitoring conducted with key stakeholders. Some early ideas to apply WSN in paddy farming shall also be briefly described, and an early initiative to apply WSN for halal food tracing will also be touched upon. Finally some topics for a collaborative research programs among a few universities shall also be related, focusing on mobility and autonomous networks. It is hoped that through the sharing of the experience various issues that we shall highlight will be deliberated and some general principles could be learned.
