Abstract
The Internet of Things (IoT) opens up tremendous opportunities to provide location-based applications. However, despite the services around a user being physically adjacent, common IoT platforms use a centralized structure, like a cloud-computing architecture, which transfers large amounts of data to a central server. This raises problems, such as traffic concentration, long service latency, and high communication cost. In this paper, we propose a physical distance-based asynchronous messaging platform that specializes in processing personalized data and location-based messages. The proposed system disperses traffic using a location-based message-delivery protocol, and has high stability.
Highlights
With the recent development of network and embedded system technologies, interest has grown in the Internet of Things (IoT)
Despite the devices being physically adjacent, common IoT platforms transfer large amounts of data, generated by multiple devices, to a central server via a global network. This causes problems, such as network congestion due to traffic concentration, service-delay problems caused by multi-hop communication, and a high communication cost because the device is always connected with a centralized server via a global network
The proposed system is composed of (1) a wireless communication proxy that is responsible for direct communication between various mobile nodes; (2) a self-organizing localized IoT messaging hub (SLIM Hub) that makes up the autonomous overlay network; and (3) an ePost-it messaging platform that provides a common format for the services
Summary
With the recent development of network and embedded system technologies, interest has grown in the Internet of Things (IoT). Many mobile objects require a complex network protocol, like 6LoWPAN (IPv6 over Low-power Wireless Personal Area Networks) or TCP/IP (Transmission Control Protocol/Internet Protocol), to connect to a network. This is difficult to implement in mobile phones and resource-constrained embedded systems like wearable devices. The proposed system is composed of (1) a wireless communication proxy that is responsible for direct communication between various mobile nodes; (2) a self-organizing localized IoT messaging hub (SLIM Hub) that makes up the autonomous overlay network; and (3) an ePost-it messaging platform that provides a common format for the services.
