The volume of data that the billions of things lying at the edge of the Internet of Things (IoT) will generate needs a comprehensive strategy for protocol mediation, processing, analysing, storing, securing, applying, and even sharing data to deliver value-creating and scalable use cases to industries and consumers. <\/p>\n
But, while trying to figure out how to manage Big Data, it is easy to forget that, when it comes to the IoT, it is actually the little things that matter. <\/p>\n
With the objective of maximising energy efficiency, many sensors are configured to only send small packets of data which, for convenience sake, can be called small data. <\/p>\n
Small data is, for example, the temperature inside the storage area of a truck carrying perishable goods, sent out once every 10 minutes. <\/p>\n
It is the data relayed from a sensor placed above a parking bay that notes when the space is taken. Or the tiny packet of data relayed once a day from a water level sensor inside a reservoir, logging whether it is submerged or not. <\/p>\n
Small data gives context and enables us to identify patterns in behaviour, enabling machine learning, and driving data analytics, opening up a big world of opportunity. <\/p>\n
The amount of data sent out in each case is minuscule often no more than just a few bytes in size. And it needs to be, since larger data packets can place a heavy payload burden on the base station of a wireless IoT network that needs to connect and service millions of things. <\/p>\n
Hence, while it is easy to say dont sweat the small stuff, for the IoT, it is the small stuff that truly matters. <\/p>\n
This is because all these small data packets eventually make up larger data sets from which to draw certain information. <\/p>\n
Take for example the parking-bay-sensor data mentioned earlier. Using the collected data from a parking lot over a period of months, the shopping centre management can trace a pattern of busy periods and quiet ones. <\/p>\n
This enables them to notify tenants when to run specials to attract more customers. <\/p>\n
As IoT usability expands, the reliance on small data packets that deliver more points of context become even more important. <\/p>\n
In certain use cases, a whole cascade of events will be triggered as soon as one sensor sends through specific data. <\/p>\n
One case in point is a patient being monitored at home something we will see a lot more of as telehealth becomes more commonplace. <\/p>\n
When accelerometer data from a wearable on an aged patient records an abrupt stop, it might indicate an injurious fall. <\/p>\n
This will trigger an automatic notification to the next of kin and the patients doctor. If no further movement from the patient is detected for a certain time, emergency services will be alerted to dispatch an ambulance. <\/p>\n
Furthermore, the patients smart home security system could also send out an access code once the ambulance crew arrives. This complete range of events is subject to the reliability of a small data sensor and a trustworthy network. <\/p>\n
To ensure the dependability of small data emanating from IoT sensors, SqwidNet, a subsidiary of DFA, is rolling out the SIGFOX IoT network in South Africa. <\/p>\n
The SqwidNet network is purpose built for listening to and delivering small packets of contextual data from these billions of connected things. <\/p>\n
Importantly, the SIGFOX standard ensures low-power usage, which is key to maximising sensors battery life. <\/p>\n
Since the launch in November 2016, they have successfully deployed the network across all of South Africas eight major metros and they currently cover over 47% of the population. <\/p>\n
The network will exceed 85% of the population by the end of the year. <\/p>\n
While the growth of IoT is a given, it is important to ensure that the foundations being laid now are stable and futureproof. <\/p>\n
To this end, securing small datas place in the setup remains crucial. It its one small step for data; one giant leap for IoT. <\/p>\n
