Routing Techniques and Protocols for Internet of Things: a Survey

With massive technological advancements and the growing popularity of digital assistance in everyday life and work environments that goes along with it, technologies are needed to evolve these application domains to the next level. One vision for this is the Internet of Things (IoT).Interconnected devices, embedded in all kinds of objects. In order to turn this vision into reality, routing protocols are needed to aid the communication between these things in a decentralized, self-organized and changing infrastructure. We are witnessing the formation of an Internet of Things (IoT), where real-world entities (e.g., people, plants, cars) augmented with computing devices (e.g., smartphones, tablets, sensor nodes), sensors (e.g., humidity sensors, microphones, cameras), and actuators (e.g., motors, LED) are connected to the Internet, enabling them to publish their generated data on the Web. By mashing up these Smart Things with the services and data available on the Web, novel IoT applications can be created a routing service is required to enable efficient communication of information among Smart Things and other Internet nodes. Due to the resource limitations of Smart Things, the design of this is challenging
