We have come a long way since the IEEE Computer article by Mark Weiser in which he envisioned small connected computers that ubiquitously enhance all aspects of our life. In this opening article of the IEEE IoT Connection, we put forward our analysis of the architectural leitmotifs we should pursue for the Internet of Things ecosystem in order to repeat the staggering success of the Internet that resulted in the introduction of the World Wide Web. By success, we mean the economic value, social and technological innovation these platforms have brought to the world.

Bluetooth Low Energy was designed as a low-power alternative to classic Bluetooth. However, the use of BLE in dense Internet of Things deployments results in high collision rates and wasted energy. To alleviate some of this contention, we present opportunistic listening, an extension to BLE active mode targeting IoT deployments with large numbers of tags and small numbers of scanning devices. For dense deployments of passive advertising devices, we present the design of Smart LaBLEs (BLE-enabled, electronic, de-centralized hubs), which aggregate multiple advertisements across similar products in a retail environment.

How do you combine the strengths of the Web with the native capabilities of the phone? Anyone who has learned how to write a native mobile application knows that it's not straightforward. If developers could apply their knowledge of designing Web applications to smartphone application design, they could leverage years of experience to rapidly accelerate phone application development. In this article, we describe the approach, introduce the Argos system, compare Argos with related platforms, detail its architecture, and discuss current conclusions and future work.
