Taxonomy of Routing Protocols

IoT has gained popularity in the networking as well as in day to day life such as smart watches, computers, smart phones, smart electronic devices. IoT is generally for providing a communication infrastructure between two ends having various issues such as availability, mobility, performance, data security, congestion control, load balancing. In this paper, detailed discussion about IoT routing protocols that are directly or indirectly using in the IoT environment. This review paper studies different routing protocols based on networking layer, network structure based(flat, hierarchical, location), path/route discovery based routing protocols has sensibly reviewed in detail on basis of various parameters, the advantages and the difference between them. Finally, in the last of research we identified different routing issues and challenges which need to be addressed in the coming future scope. This study focuses on data routing in the IoT. The aim is to not only interpret, correlate, and summarize previous research, but also to understand and examine their results in relation to the Internet of Things.
