This paper deals with the replica placement problem on fully homogeneous tree networksknownasthe Replica Placementoptimizationproblem. Theclient requests are known beforehand, whil...
P2P systems are increasingly used to discover and share various data between users. The performance of a P2P based information retrieval system is determined by the efficiency of...
Each Internet communication leaves trails here or there, that can be followed back to the user. Notably, anonymous communication schemes are purposed to hide users' identity ...
— We introduce an algorithm which detects and traces a specified level set of a scalar field (a contour) on a plane. A network of static sensor nodes with limited communication...
This paper presents a coordination algorithm for mobile autonomous robots. Relying upon distributed sensing, the robots achieve rendezvous, that is, they move to a common location....
