Why did the logistics soldier cross the road?

What is Pervasive Computing (PvC)?

The goal of pervasive computing (PvC) is to make data and application services available to any authorized user anywhere, anytime, and on any device.

Create an environment where “everything” is a compute node which communicates wirelessly and interacts seamlessly with humans.

Conclusion

PvC is important! It is here, and moving quickly. Let’s pick an architecture that scales, offers security, and

gives us a platform on which to build applications more rapidly.

We need strong middleware on the device and on the back-end.
