  Traditional web communication technologies, such as the Hypertext Transfer Protocol (HTTP), provide a uni-directional link and a request/response message exchange model. This solution can be troublesome in web-based applications involving a large number of different interconnected devices, such as in the Internet of Things (IoT). In this thesis, we design communication patterns suitable for scalable and low-latency web-based IoT applications. We further evaluate different technologies to realise such applications. Among them, we focus on the WebSocket protocol, that provides bi-directional communication mechanism through a single socket, thus reducing unnecessary communication overhead and redundant TCP connections. We also consider the WebSocket Application Messaging Protocol (WAMP), a WebSocket subprotocol, to implement some of the considered communication patterns – namely, Publish/Subscribe and Remote Procedure Call – in the IoT. As a case study, we implement web-based IoT applications for the scenarios represented by home automation and social sensing. We further evaluate the performance of WAMP over WebSocket against other protocols commonly used in IoT applications.
