A given of modern embedded systems design is that with ubiquitous wired and wireless connectivity, many aspects of the development process have had to be re-evaluated. This is particularly true of securing and protecting connected devices and operating them in ways that sacrifice neither power efficiency nor performance. My Editor's Top Picks of new articles that deal with some of these issues are:

Simplify embedded Wi-Fi connectivity with NFC
Optimizing for low power in embedded MCU designs
Using sensor controllers to reduce mobile power

In addition, this week at ESC DESIGN East there are about 30 classes available to bring you up to speed on the latest information on these issues. In addition to a panel session on "Internet of Things, Intelligent Systems, Smarter Planets and Future Cities (TH-2007)," My Editor's Recommendations are:

Embedded IPv6: What's the beef? (ESC-4003) by Thomas Cantrel of Green Hills Software
Using RFID for wireless systems connectivity (ESC-3023) by Tego's Bob Hamlin

Reactive or proactive power management (ESC-2008) by Adam Kaise, Mentor Graphics
Maximizing battery life on embedded platforms (ESC-2015) by ARM's Christopher Shore

Security fundamentals for embedded software (ESC-1010) by David Kalinsky
Embedded security by design (ESC-3005) presented by Bruce Douglass of IBM

(Editor's Note: You may have noticed that the newsletter format has a new look. Embedded.com has a new look also as part of its relaunch this week as an independent online site. Read "Welcome Home" by Colin Holland for more details.)

A Framework for Considering Security in Embedded Systems

The need for security in many embedded systems is not always readily apparent, and too many embedded systems designers are paying too little attention to the subject, despite the increased wired and wireless connectivity of such designs.

Enhance system security with better data-at-rest encryption

Embedded systems designers can protect sensitive data that's on a device's hard drive (data-at-rest) by using encryption techniques.

Best practices: Improving embedded operating system security

Bill Graham reviews some of the security best practices that embedded systems need to pay attention to in their designs, particularly those requiring the use of real time embedded operating systems (RTOS)in mission and safety critical systems used in industrial and medical devices.

Security fundamentals for embedded software

Even if your device is not connected to the Internet, you need to protect it from malicious attacks. Here are some simple protections you can institute to make your system more impenetrable.

Smart management is the key to smart grid meter security

Addressing the security of meters in emerging smart grid applications requires a secret key management strategy that does not store keys on any node, authenticates each node, verifies communications, and uses temporary communication keys that are rotated often.

Expanding the Embedded Universe: Migrating From IPv4 to IPv6

With the imminent exhaustion of IPv4 address space, and a mounting number of embedded devices pushing the limits, it is time to move to IPv6. Here's how IPv6 corrects three problem with IPv4 and what you need to know to make the shift.

Clearing up the mesh about wireless networking topologies: Part 1

A two part series updates you on wireless mesh networking, comparing traditional approaches such as Zigbee to more deterministic topolologies such as Wireless HART, 6LowWPAN, and adhoc on demand vector routing (AODV). Part 1: The basics.

Pick the right wireless sensor/controller for your connected MCU-based design

Kim Rowe takes you step by step through the process of selecting the hardware and software building blocks necessary for building a wirelessly connected microcontroller design.

Build wireless M2M and IoT sensor networks: High quality and low power design

In the conclusion of a four part series, the authors of "Ad hoc wireless networks," look at the remaining challenges in wireless sensor network design relating energy efficient hardware design, synchronization, transport layer protocols and real time communications.

Software Matters for Power Consumption

Whether you are creating an operating system, firmware, or even device drivers, the way you write the software could affect the power consumption of the resulting product. Here are four approaches to minimizing power consumption through software.

A new way to benchmark energy costs of embedded processor performance

A guide to developing certifiable measurements of performance and energy consumption for processors and embedded systems and the measurement techniques incorporated into EEMBC's EnergyBench can be used for making necessary tradeoffs.

Energy efficient C code for ARM devices

Here is an overview of some of the techniques for optimizing C-code for use on the ARM architecture. (Paper from ARM TechCon 2010.)

In the latest version of its Linux platform, Wind River has incorporated much of the Yocto Project open source development infrastructure and achieved Yocto Project compatible registration.


Insights

Welcome home . . .

A few months ago when Embedded System Design magazine was closed I promised that we would redouble our efforts to provide the embedded development community with an unrivaled source of information on Embedded.com.

Internet Protocol infiltrates low-power machine-to-machine networks

The 6LoWPAN work is opening low-power wireless networks to IP traffic, with interesting consequences.

WSNs & the future of the deterministic Internet

According to recent studies the wireless sensor networking chip market grew by 300% in 2010 and is doubling yet again this year. More important for embedded systems developers, wireless-enabled sensor spending grew by 80% in 2010. But with great opportunities come great challenges.

Pub/sub, the Internet of Things, and 6LoWPAN connectivity

The pace of development of next-gen Internet of Things networks is speeding up, driven by a first wave of devices using paradigms such as the lightweight MQTT protocol for delivery over current Wi-Fi and Zigbee wireless sensor networks followed by nextgen IPv6-based 6LoWPAN in a variety of wired and wireless environments.

UDP and the embedded wireless Internet of Things

The creation of the 6LoWPAN wireless extension to the IPv6 promises a wealth of opportunities for creating an embedded "Internet of Things." But to take advantage of them means solving some significant problems as well.
