Social Web of Things services fault handling and queuing scheduling

The Internet of Things (IoT) has been widely used in the past few years. Exploiting sensors and objects to offer personal services is very common today. WoT extends IoT to HTTP level for object representation and message exchanges among users, devices and service providers through Web services. Due to the nature of WoT objects and instability of the Internet, ensuring the reliability of message passing in WoT became a big challenge.

This work presents a retry scheme for Web services fault handling in RESTful based WoT. To handle messages retry we adopted three different retry queuing schemes. Experiments are conducted to illustrate the performance and effectiveness of the proposed fault handling schemes.
