Micro Search Engine for IoT: An IoT Search Engine Prototype for Private Networks

Abstract

Background: The Internet of Things (IoT) has been heralded as the "next big thing" waiting to be realized. IoT revolves around increased machine-to-machine communication and it encompasses various embedded sensorsand actuators that assist users in monitoring and controlling objects remotely in many fields and applications. Methods: IoT's special characteristics introduce challenges in the field of retrieval technology. These challenges constitute of real-time data retrieval with the huge amount of data that can be produced from the sensors. This paper explains the design concepts used to develop a search engine for IoT to tackle these issues. The developed search engine appears to be promising. The performance of the network proved very powerful under normal conditions, however, it could not sustain heavy load under the stress test due to the restricted build of the Z1 motes. Results: The searching capability proved to be quite strong in terms of searching speed and acceptable results; however more tests need to be ▻ Authors ▻ Keywords

Internet of things search engines: toward a general architecture

“…By analyzing a set of works [2], [5], [9], [11]- [29] in the literature related to IoT search engines and IoT resource discovery and control. We discover the existence of an important number of IoT search engines, and we conclude that every search tool has some relative strengths.…”

“…This infrastructure is compatible with any service-oriented architecture (SOA)-based middleware solution that supports the Subscribe/Notify communication model, as well as the data request mode using eXtensible markup language (XML) and web services. A search engine for private IoT networks has been proposed by Habaebi et al [5]. It is a simple, efficient and secure micro search engine that allows users to browse private databases, find and collect data in a useful and secured way.…”

“…Searching in IoT networks has a different goal than the ones that typical search engines adapt where the users would operate the objects locally or remotely. As a result, this distinguishes between both sides and requires a new design concept for an IoT search engine [5]. IoTSE is a complicated and relatively immature research topic.…”
