Adaptive scheduling over a wireless channel under constrained jamming
(2015)We consider a wireless channel between a single pair of stations (sender and receiver) that is being “watched” and disrupted by a malicious, adversarial jammer. The sender’s objective is to transmit as much useful data as ...

Advanced Array Optimizations for High Performance Functional Languages
(1995)In this paper, we discuss and evaluate three opti- mizations for reducing memory management overhead and data copying costs in SISAL 1.2 programs that build arrays. The first, called framework preconstruction, eliminates ...
