Reliable Data Delivery in large scale IoT networks using Hybrid Routing Protocols

Abstract

The Internet of Things has turned the world upside down and brought bil
lions of devices on line to share data effortlessly. The need for reliable and 
efficient data delivery in IoT networks has grown along with network size 
and complexity. In an effort to optimize communication in large scale IoT 
ecosystems, this article explores the emergence of hybrid routing protocols 
as a potential solution. The continuously growing IoT deployments have made 
heterogeneous and dynamic network environments more and more a reality. 
Classical routing schemes are insufficient in serving the special characteris
tics of the IoT – limited energy resources, diverse traffic grades, and frequent 
topology modification. In order to get over these limitations, Hybrid routing 
protocols are designed to combine the strengths of multiple routing para
digms. Hybrid protocols combine proactive and reactive routing elements 
to accommodate changes in IoT applications’ demands, while still utilizing 
the best performing routing solution. Through this adaptive approach, more 
efficient use of network resources, better scalability and reliability in data 
delivery is achieved over extensive IoT infrastructures. In the subsequent 
sections we provide an overview of some of the basic concepts of hybrid 
routing for IoT and consider protocol design and how they work in practical 
implementations. In addition, we will also talk about the current emerging 
trends and future directions of this fast advancing field. By understanding 
this comprehensive analysis, readers will understand the role hybrid routing 
plays in allowing next generation large scale IoT networks.
