A state of the art Smartphone such as the iPhone 4 or Samsung Galaxy S2 is loaded with various sensors, such as motion sensors and accelerometers, a gyro, a camera (or two), a microphone, WiFi and Bluetooth radios (which can be used both for communication and for sensing RF signals), Near Field Communication (NFC), a touch screen, etc.

In addition, they are increasingly equipped with high performance processors, such as the 1.2 GHz dual core Cortex-A9 processor of the Galaxy S2. And of course, these phones run a fully-fledged operating system and modern developing languages such as Java. All this comes with a price tag of $500-$900.

Compare this with modern mote sensing nodes, having a memory of a few Megabytes, a terribly slow processor, and running a special purpose OS like tinyOS, which requires unique programming skills and development environments, while priced at $100-$150, with each sensor costing an extra few bucks. Given the economy of scale of smartphones and the tough competition in this market, their prices are likely to be halves within a year, as new models come in. Moreover, when cellular communication in not important, one can settle for the Galaxy S WiFi for around $400.

Given the cost of programmers, with the exception of extremely large deployments, it is cheaper to use smartphones than sensor nodes. In terms of lifetime, sensors can typically survive longer than smartphones. Yet with an extra battery, one can dramatically prolong the latters’ capabilities as well and still be affordable.

Even more interesting is the ability to utilize smartphones for crowdsourcing sensor networks. Consider for example earthquakes. When an earth quake occurs, naturally all phones in the area will shake.

Hence, by having all phones that shake beyond some threshold report to a cloud server both the magnitude and nature of the shaking as well as their position, either over their data channel  or by SMS, the server could compute whether an earth quake is happening and what its magnitude is. Based on this, warnings can be sent out to other areas to prepare for the earthquake, e.g., by shutting elevators and power plants, securing hard disks of important computers, and the likes.

Similarly, mobile phones can be crowd-sourced to detect noise hazards, excessive RF radiation, etc. One company that already does something along these lines is Waze, which crowd-source mobile phones to detect traffic jams. I am sure others will soon follow.

It seems to be bon-ton these days to talk about the end of Moore’s law. While originally stated for the number of transistors stored on a given area of silicon, it has been quickly extended to CPU clock speed and performance as well.

In general, for a long time, the number of transistors in a CPU and its clock speed used to double every 1.5 to 2 years. All this was going on until around 5 years ago. Due to laws of physics, the heat and energy grow roughly cubically in the clock speed and so increasing the clock speed above 3 GHz seemed impractical.

As a result, rather than increasing the clock speed, chip manufacturers opted for increasing the number of cores in a CPU, thereby increasing the theoretical performance by adding parallelism rather than by increasing the clock speed.
Yet, even this trend may soon be put to a serious challenge, as the distances between transistors quickly become smaller than the minimal required by CMOS technology.

All this is great news for computer science in my opinion. For a long time, people got used to being lazy. If computers become twice as fast every 1.5 to 2 years, there is no point in investing much efforts in writing efficient code.

If something does not run fast enough, simply wait for the next generation of Intel x86 and everything will be resolved. In particular, CPUs became fast enough that traditional programming languages and efficient data structures and algorithms were being abandoned in favor of high level scripting languages whose most sophisticated data structure is an associative array. Suddenly, every Joe-hoe could become a programmer developing sophisticated Web applications with no effort  – no need for hard earned computer science degrees anymore.

All these could change back with the end of Moore’s law. As CPUs become parallel, programmers need to learn how to write parallel code and deal with all the intricacies of concurrent execution. They need to understand how the system executes their code, dealing with memory consistency issues, avoiding synchronization in order to facilitate parallelism etc.

There is suddenly great demand for innovation in compiler technology for automatically parallelizing sequential programs. Programming models are suddenly an important topic again. Data structure libraries need to be parallelized in an efficient and scalable manner. Operating systems must be redesigned and re-architected to make an effective use of the many cores that are put at their dispense.

Moreover, as the number of transistors might be reaching a limit, this means that even the number of cores on a CPU will likely be limited. Also, given Ahmdel’s law, the maximal benefit from parallelism is in any case quite limited. Hence, writing efficient code will suddenly become important again. For this, strong background in computer science is a must!
