Abstract

To connect agricultural wireless sensor networks (WSNs) to web services and applications, the agricultural WSNs/WoT gateway is empowered with local data management and network maintenance functions for downstream WSNs in addition to traditional upstream data collection. This work demonstrates a low-cost, highly scalable, rapidly deployable web of things (WoT) gateway with edge computing capabilities. First, an agricultural WSNs/WoT topology is architected, connecting a ZigBee WSNs to the Web for remote monitoring the local environmental and agronomical information, and simultaneously for managing the solar-powered WSNs for a prolonged lifespan according to the instant data scrawled from the cloud. Second, a WSNs/WoT gateway is designed with the hardware platform Raspberry Pi 3, which serves multiple needs for bidirectional information exchange and local WSNs management. Finally, experimentation demonstrates the proposed hardware platform and architecture can perform edge computing, and efficiently realize the up and down transmission and distribution of data stream.

2. Architecture Of The Agricultural Wot

The rapid development of embedded technology, sensor network technology, and RFID technology has provided support for the interconnection among objects. A wide variety of smart things, complex transformations between different network protocols and application exclusivity have led to the complexity of inheritance among the WoT. Therefore, the Web of Things technology that combines Web technology and WoT technology has emerged (Gubbi et al., 2013; Khan et al., 2012). WoT integrates smart things, such as RFID tag objects, sensor nodes, etc., using web technologies to provide an open platform for the WoT. WoT application development can simplify the application integration of intelligent objects by making full use of mature Web development tools, programming languages and methods, and also can realize the fusion between the physical space of intelligent objects and the virtual space of web applications (Ferdoush & Li, 2014).
