In the store-and-forward routing problem, packets have to be routed along given paths such that the arrival time of the latest packet is minimized. A groundbreaking result of Leighton, Maggs and Rao says that this can always be done in time O(congestion + dilation), where the congestion is the maximum number of paths using an edge and the dilation is the maximum length of a path. However, the analysis is quite arcane and complicated and works by iteratively improving an infeasible schedule…

Near-Optimal Schedules for Simultaneous Multicasts
TLDR
A lower bound for multicasts is proved, which shows that there do not always exist schedules of non-trivial length, which means that this length cannot be improved to O(C+D) + o(\log n)$.
Near-Optimal Scheduling of Distributed Algorithms
TLDR
This paper presents a distributed algorithm that produces a near-optimal O(congestion + dilation log n) round schedule, after O(dilation log2 n) rounds of pre-computation, and a key challenge in the latter result is to solve the problem with only private randomness, as globally-shared randomness simplifies it significantly.
Coordination Mechanisms for Selfish Routing over Time on a Tree
TLDR
This paper focuses on tree networks, and designs a coordination mechanism with polylogarithmic price of anarchy for weighted jobs and shows that price of Anarchy is a function of the depth of the tree.
Oligopolistic Competitive Packet Routing
TLDR
This work proves the existence of a pure Nash equilibrium and shows that it can be constructed by sequentially computing an integral earliest arrival flow for each player, and derives several tight bounds on the price of anarchy and theprice of stability in single source games.
Train Scheduling on a Unidirectional Path
We formulate what might be the simplest train scheduling problem considered in the literature and show it to be NP-hard. We also give a log-factor randomised algorithm for it. In our problem we have
Scheduling Trains with Small Stretch on a Unidirectional Line
TLDR
It is proved that minimizing max-stretch is NP-hard even on this simple network, and an O(1)-approximation algorithm is given, which can be interpreted as packet scheduling on in-comb, a special case of in-trees.
An efficient load balancing method for ad hoc networks
TLDR
2 new metrics for ad hoc networks are proposed and defined: bandwidth utilization ratio and load index, which can be used as an indicator to measure and monitor the network usability and to improve its efficiency by efficient load distribution.
Computation-Aware Data Aggregation
TLDR
A model of distributed computation that considers both computation and communication so as to give a theoretical treatment of data aggregation is introduced and a polynomial-time algorithm is given that computes the optimal schedule when the input network is a complete graph.
The Moser-Tardos Framework with Partial Resampling
TLDR
A partial resampling approach that resample an appropriately-random subset of the set of variables that define this event, rather than the entire set as in Moser & Tardos, leads to several improved algorithmic applications in scheduling, graph transversals, packet routing etc.
1 k-uniform Hypergraph Coloring
TLDR
The probabilistic method is a proof technique for showing the existence of a mathematical object by constructing random objects and then trying to find out if any of the authors' randomly constructed objects do not work.

This work provides efficient routing strategies yielding origin-destination paths of bounded dilation and congestion and can give good a priori guarantees on the time required to send a given set of messages which implies that all messages can be scheduled to reach their destination on time.
