Content distribution by multiple multicast trees and intersession cooperation: Optimal algorithms and approximations
—The paper addresses the problem of massive content distribution in the network where multiple sessions coexist. In the traditional approaches, the sessions form separate overlay...

Classical Planning in MDP Heuristics: with a Little Help from Generalization
Heuristic functions make MDP solvers practical by reducing their time and memory requirements. Some of the most effective heuristics (e.g., the FF heuristic function) first determ...

Lifetime-resource tradeoff for multicast traffic in wireless sensor networks
In this paper, we study the problem of supporting multicast traffic in wireless sensor networks with network coding. On one hand, coding operations can reduce power consumption and...

SIMD Vectorization of Histogram Functions
Existing SIMD extensions cannot efficiently vectorize the histogram function due to memory collisions. We propose two techniques to avoid this problem. In the first, a hierarchi...
