Resource Management in Internet of Things: A Routing Perspective

Internet of Things (IoT), the latest and most popular development in the field of Information and Communication Technology (ICT), requires the intermingling of different technologies like networking, cloud, and analytics. Networking portion of IoT is handled mainly by the Low Power Lossy Networks (LLNs), which in turn plays notable role in the proper functioning of other components including cloud platforms. As a result, resource management within LLNs is an issue that can't afford to be left out. The paper analyzes this concern through an elaborate study of LLN routing protocols including RPL, LOADng, and opportunistic routing protocols. The survey has been conducted so as to flash light on resource management capabilities of these protocols. Accordingly, a mapping has been provided between the features of different protocols and the resources managed by each of those features. Finally, the paper enlists concerns demanding immediate attention, coupled with possible solutions, so as to ensure the efficient functioning of an approaching smart world.
