A Design and Implementation of Information Service Architecture for Resource-Constraint Devices in Internet of Things

Billions of smart devices will be connected to the Internet to form the Internet of Things. The core value of IoT (Internet of Things) is to supply information services through the huge amounts of devices. Most of sensors, actors and terminal equipment such as mobile phones are resource-constrained in battery, bandwidth, storage and computation ability. Accordingly, we propose an information service architecture for IoT, which is a four-layer design including perception layer, network layer, service layer and process layer. We compare the data transmission methods in a resource-constrained condition and find that REST (Representational State Transfer) technology is more suitable. We analyze the device discovery process, and we implement the information service of image searching and video sharing based on the proposed architecture by using Restful technology.
