the rapid development of sensor technology, WSNs are expected to become a key IoT technology. Wireless I/O Connectivity Modules and Gateway Solution For engineers, the greatest challenge of designing for the IoT is ensuring wireless connectivity. The concept of the IoT involves not only new devices designed with IoT compatibility, but also existing systems that operate outside the IoT cloud. However, to establish a ubiquitous cloud of interconnected devices, non IP-based devices must be able to connect to each other without requiring Ethernet or a Wi-Fi interface and accompanying protocol stack. This can be achieved using wireless I/O interface modules and gateways that enable Internet access in the context of real-world

applications. Furthermore, adding intelligent sensor control software to gateways can simplify the design of IoT systems by providing access to shared processing resources. This paper addresses the implementation of IP connectivity, security, disparate node aggregation, device management, as well as a software development kit (SDK) that enables customization. Considering the demands of potential applications, Advantech’s WISE- 3000 gateways and WISE-1000 wireless I/O modules can satisfy most customer requirements. Using a WISE-100 wireless I/O module and WISE-3000 gateway, system integrators can easily connect existing control devices and sensors to IoT systems for data collection and device control based on the results of subsequent data analysis. When combined with a WISE-1000

In today’s world, the infrastructure provided by smart city and industrial automation systems enables continuous connectivity. The commonality shared by such systems is their association with the Internet of Things (IoT). With the inclusion of sensors and control devices, entire infrastructures can be integrated with information and communication technologies, resultinginnetworkedandembedded devices that enable intelligent monitoring and management. With the easy deployment and flexibility of sensor devices, wireless sensor networks (WSN) can comprise numerous sensor nodes that collect information. The collected information then provides a database for further analysis; the results of which can be used to improve the reliability and efficiency of existing infrastructure systems. Considering
