Searching in Internet of Things: Vision and Challenges

This paper discusses the challenges in searching imposed by the burgeoning field of Internet of Things (IoT). It first overviews the evolution of the new field to its predecessors: searching in the mobile computing, ubiquitous computing and information retrieve. Then, it identifies four research thrusts: architecture design, search locality, real-time and scalability. It also sketches several presumptive IoT scenarios, and uses them to identify key capabilities missing in today's systems. This paper concludes with a discussion of the research necessary to design and develop these capabilities. In addition, this paper proposes a series of measurement dimensions, based on which it investigates the state-of-the-art efforts.
