Routing Issues in Internet of Things: A Survey

“Everything that is connected to the internet is alive”, is going to be the new rule for future. Future is Internet of Things (IoT), we are moving towards it with rapid pace. Often to the way humans use internet, now onwards devices will be the main users of IoT ecosystem [3]. Recent research deeds capitalizing on the state of the art technologies to build a scalable IoT [4]. However, the comprehension of IoT framework is slowed down because of some factors, out of that the most critical are integration of the devices which are heterogeneous, secure communication between them, trust management and cooperation within such devices and nodes. These devices communicate with each other for gathering, sharing and forwarding the information in multihop manner [3]. IoT generates enormous data continuously, therefore for creation of an intelligent environment, the collected information needs to be transformed into intelligence. This intelligent environment may play a vital role while routing the data in the network. Many nodes in IoT undergo constant movement that may result into intermittent interconnectivity between the devices which may encounter frequent topology changes. Due to these frequent topological changes and limited resources available in the IoT devices, now a day’s routing of the data has become a great challenge in front of the today’s research community. This survey emphasizes on routing of the data in IoT. The goal is not only to analyze, compare and consolidate the past research work but also to appreciate their findings and discuss their applicability towards the IoT.
