Routing in Internet of Things: Review

The unification of the sensor devices, Internet and Radio Frequency Identification frame-works has instigated the idea of Internet of Things (IOT), which helps to connect our daily things, making them smart through perception of signals, thinking, and collaborating with other devices. The IOT frame work tries to connect anybody with anything at anyplace, in spite of the fact that the internet of things becoming a key framework for the improvement of smart IOT network. IOT network has the great potential for the extensive variety of applications like smart City, smart homes, atmospheric condition, human health monitoring, logistics, and so forth. To transfer this IOT visualization into actuality, routing protocols are essential to create bridge between these devices in a decentralized, self-composed and changing infrastructure. Large numbers of nodes in the IOT may subject to constant mobility that may leads to asymmetrical interconnection between the devices which may results in the dynamicity of the topology. Because of this topological variations and constraint resources in IOT devices become great challenge of routing in IOT. In this paper we made survey on several papers to know the cluster based IOT network, IOT routing, routing techniques, issues and challenges in IOT.
