  Internet of things (IoT) has emerged as a new paradigm for the future
Internet. In IoT, enormous devices are connected to the Internet and thereby
being a huge data source for numerous applications. In this article, we focus
on addressing data management in IoT through using a smart data pricing (SDP)
approach. With SDP, data can be managed flexibly and efficiently through
intelligent and adaptive incentive mechanisms. Moreover, it is a major source
of revenue for providers and partners. We propose a new pricing scheme for IoT
service providers to determine the sensing data buying price and IoT service
subscription fee offered to sensor owners and service users, respectively.
Additionally, we adopt the bundling strategy that allows multiple providers to
form a coalition and bid their services as a bundle, attracting more users and
achieving higher revenue. Finally, we outline some important open research
issues for SDP and IoT.
