(200507)In the paper, we perform an indepth analytic study of the binary exponential algorithm (BEBA) that is widely used in distributed MAC protocols, for example, IEEE 802.11 DCF. We begin with a generalized framework of modeling ...

AVCast: New Approaches For Implementing AvailabilityDependent Reliability for Multicast Receivers (200605)Today's largescale distributed systems consist of a collection of nodes that have highly variable availability . a phenomenon sometimes called churn. This availability variation is often a hindrance to achieving reliability ...

(200902)Many questions about homotopy are provably hard or even unsolvable in general. However, in specific settings, it is possible to efficiently test homotopyequivalence or compute shortest cycles with prescribed homotopy. We ...

(iSchools, 20160315)Gravity is one the principle forces in the universe, its power always apparent, giving us threedimensional creatures a constant sense of “up” and “down”. We propose the use of a metric for applying gravity, or similar ...
