Internet of Things has started contributing in all sectors, be it agriculture, transportation or healthcare. The industry is looking forward to unleash the potential of revolutionary technology called Internet of Things. Although IoT is making huge inroads in every sector, but efficient delivery of services still remain a concern. Also, Agile Methodologies are increasingly being adopted across the software development industry. This paper briefs the concept of Internet of Things, followed by exploring the prospects of modeling Agility in Internet of Things Architecture to provide for better delivery of services and improved Quality of Service. In this paper, we focus on the potential of making Internet of Things more agile and flexible. The Internet of Things can exploit an advancing market open to new and innovative services. Complex and ever-evolving business requirements demand adoption of agile services in Internet of Things applications. Further, this paper intends to leverage the benefits offered by Agile Services in the application fields of Internet of Things ranging from smart agriculture and intelligent transportation to smart healthcare and logistics optimisation.
