The importance of network architecture on the Internet of Things
This article is part of a series exploring the role of networking in the Internet of Things.
There are a lot of moving parts in the networking for the Internet of Things; a lot to sort out between WiFi, WiFi LP, Bluetooth, Bluetooth LE, Zigbee, Z-Wave, EnOcean and others. Some standards are governed by open, independent standards bodies, while others are developed by a single company and are being positioned as defacto standards. Some are well established, others are in the early adoption stage. All were initially developed to meet unique application-specific requirements such as range, power consumption, bandwidth, and scalability. Although these are familiar issues, they take on a new urgency in IoT networks.
To begin establishing the right networking technology for your application, it is important to first understand the network architecture, or the network topology, that is supported by each technology standard. The networking standards being used today in IoT can be categorized into three basic network topologies; point-to-point, star, and mesh. Read more…
Using technology to prevent rat outbreaks.
If the modern city is a symbol for randomness — even chaos — the city of the near future is shaping up along opposite metaphorical lines. The urban environment is evolving rapidly, and a model is emerging that is more efficient, more functional, more — connected, in a word.
This will affect how we work, commute, and spend our leisure time. It may well influence how we relate to one another, and how we think about the world. Certainly, our lives will be augmented: better public transportation systems, quicker responses from police and fire services, more efficient energy consumption. But there could also be dystopian impacts: dwindling privacy and imperiled personal data. We could even lose some of the ferment that makes large cities such compelling places to live; chaos is stressful, but it can also be stimulating.
It will come as no surprise that converging digital technologies are driving cities toward connectedness. When conjoined, ISM band transmitters, sensors, and smart phone apps form networks that can make cities pretty darn smart — and maybe more hygienic. This latter possibility, at least, is proposed by Samrat Saha, a consultant with the DCI Marketing Group in Milwaukee. Saha suggests “crowdsourcing” municipal trash pick-up via BLE modules, proximity sensors and custom mobile device apps.
