Environmental monitoring systems using internet of things – standards and protocols

The Internet of Things (IoT) consist of smart connected devices in homes, businesses and cities that has the ability communicate over an Internet without human-to-human or human-to-computer involvement. IoT communication standards and platforms has a high potential for a wide range of applications in different domains. Collecting the data by a large number of sensors, is a challenging task because of many open issues. Effective collection and distribution are crucial for classes of smart city services such as environmental monitoring, public security, transportation, and other. Unfortunately there are many connection gaps between the raw sensor data and the information context that are needed by high-level services and applications. Utilization of some Semantic Web standards provide better integration of sensor with applications, but still is far from being solved. Therefore, we have analyzed selected standards, protocols, and architectures and have suggested some enhancements into “common semantics” model.
