Indoor visible light communications (VLC) combines illumination and communication by utilizing the high-modulation-speed of LEDs. VLC is anticipated to be complementary to radio frequency communications and an important part of next generation heterogeneous networks. In order to make the maximum use of VLC technology in a networking environment, we need to expand existing research from studies ...

We present a reduction from a concurrent real-time program with priority preemptive scheduling to a sequential program that has the same set of behaviors. Whereas many static analyses of concurrent programs are undecidable, our reduction enables the application of any sequential program analysis to be applied to a concurrent real-time program with priority preemptive scheduling.

Grids have emerged as paradigms for the next generation parallel and distributed computing. Computational Grid can be defined as large-scale high-performance distributed computing environments that provide access to high-end computational resources. Grid scheduling is the process of scheduling jobs over grid resources. Improving overall system performance with a lower turn around time is an imp...
