Final Remarks
Abstract In this chaper we summarize the contributions of this topic to advance
the state-of-the-art in the development of IoT applications. The main contributions
are: (i) to present a middleware-layer infrastructure, SmartSensor, that focuses on
the integration of Wireless Sensor Networks (WSN) in the Web, providing WSN
as a service, acessible as any other Web resource and enabling the discovery and
composition of services to form Web mashup applications; (ii) to describe step by
step the development of an application using the SmartSensor infrastructure, the
Parking Lot Application, that helps drivers to find available parking space in a build-
ing. SmartSensor is composed of three software modules: (i) the Sensor Integration
Module (SIM) integrates the distinct WSN devices and provides a RESTFUL inter-
face to access them as Web resources; (ii) the Programming and Execution Module
(PEM) enables the composition of value-added services from multiple Web sources;
(iii) the Web 3.0 Integration Module (WIM) integrates the resources with Web 3.0
applications and platforms.

7.1 Introduction
The Internet of Things (IoT) represents a new direction on the use of computers
in everyday life as it enables the integration of the Internet with the physical world,
populated with sensors, actuators, and embedded communication hardware. The het-
erogeneous physical devices become a part of the Web and can be accessible using
the well-known Internet protocols. This scenario arises the opportunity for creating
sophisticated applications based on physical world data, such as monitoring inacces-
sible and remote spaces (oil platforms, forests, tunnels, mines, pipes), environmental
