I think that Oracle is going in the correct direction. The company has chosen a right partner for the microcontroller/processor platform such as Freescale. As mentioned in this article, size is one of the key factors for IoT space. If the sized down version of embedded Have could be fit with in a couple of KB of the smallest controller, nothing better than that. But security is another important factor. Hope to see some good progress in this domain.
I like Freescale and would think that others should jump on the Java bandwagon. Having a streamlined Java for the smaller devices while allowing for IoT features will be a great enabler for growth in both the market and in applications. Which vendor will be next with Java support, I wonder?
Seems to me that Java carries significant overhead that may not make it a good IoT target. Perhaps I'm dated on this point. Anyone have some data on good MCU implementations and memory size (and needs for dynamic structures)?
Also- the recent posts here on EETimes on IoT have been fairly focused on the need for improved security. Will Java satisfy this requirement? Any efficient security structures already in Java (probably are if $ transactions are being processed all the time). Anyone care to clarify?
We have prototypes running in much smaller configurations; down to 8 kB RAM. However, that is not currently a target configuration for us since we want to offer a platform with a comprehensive feature set in areas such as connectivity, management and security. For more details on these features, see:
Thanx for the info. 1MB ROM is still very big 9in my book). Any way you can get it down to 256KB or below? A feature 'slim' version perhaps? For many high volume apps the 1MB size can be just too costly...
On the desktop, Java and .NET are roughly comparable (and are good frameworks overall). One of the best features of both is the ability to use different languages (such as Scala, Groovy, and F#) that target the runtime and can interop with Java/C#/etc code -- but I doubt that ability will make it to J2ME or the .NET Micro Framework (used in the Gadgeteer and Netduinos).
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
