Online Load Balancing Made Simple: Greedy Strikes Back
We provide a new simpler approach to the on-line load balancing problem in the case of restricted assignment of temporary weighted tasks. The approach is very general and allows to...

A practical algorithm for constructing oblivious routing schemes
In a (randomized) oblivious routing scheme the path chosen for a request between a source s and a target t is independent from the current traffic in the network. Hence, such a sc...

Routing for Network Capacity Maximization in Energy-constrained Ad-hoc Networks
— We present a new algorithm for routing of messages in ad-hoc networks where the nodes are energy-constrained. The routing objective is to maximize the total number of messages ...

A Lower Bound on the Competitive Ratio of Truthful Auctions
We study a class of single-round, sealed-bid auctions for a set of identical items. We adopt the worst case competitive framework defined by [1,2] that compares the profit of an ...

Online Scheduling with Bounded Migration
Consider the classical online scheduling problem where jobs that arrive one by one are assigned to identical parallel machines with the objective of minimizing the makespan. We gen...

Online Scheduling of Equal-Length Jobs: Randomization and Restarts Help
We consider the following scheduling problem. The input is a set of jobs with equal processing times, where each job is specified by its release time and deadline. The goal is to ...

Online algorithms for prefetching and caching on parallel disks
Parallel disks provide a cost effective way of speeding up I/Os in applications that work with large amounts of data. The main challenge is to achieve as much parallelism as poss...

Packet-mode policies for input-queued switches
This paper considers the problem of packet-mode scheduling of input queuedswitches. Packets have variable lengths, and are divided into cells of unit length. Each packet arrives t...

Mechanism design for online real-time scheduling
For the problem of online real-time scheduling of jobs on a single processor, previous work presents matching upper and lower bounds on the competitive ratio that can be achieved ...
