text: "We consider the problem of computing shortest paths in \\emph{hybrid networks},
in which nodes can make use of different communication modes. For example, mobile
phones may use ad-hoc connections via Bluetooth or Wi-Fi in addition to the cellular
network to solve tasks more efficiently. Like in this case, the different communication
modes may differ considerably in range, bandwidth, and flexibility. We build upon
the model of Augustine et al. [SODA '20], which captures these differences by
a \\emph{local} and a \\emph{global} mode. Specifically, the local edges model
a fixed communication network in which $O(1)$ messages of size $O(\\log n)$ can
be sent over every edge in each synchronous round. The global edges form a clique,
but nodes are only allowed to send and receive a total of at most $O(\\log n)$
messages over global edges, which restricts the nodes to use these edges only
very sparsely.\r\n\r\nWe demonstrate the power of hybrid networks by presenting
algorithms to compute Single-Source Shortest Paths and the diameter very efficiently
in \\emph{sparse graphs}. Specifically, we present exact $O(\\log n)$ time algorithms
for cactus graphs (i.e., graphs in which each edge is contained in at most one
cycle), and $3$-approximations for graphs that have at most $n + O(n^{1/3})$ edges
and arboricity $O(\\log n)$. For these graph classes, our algorithms provide exponentially
faster solutions than the best known algorithms for general graphs in this model.\r\nBeyond
shortest paths, we also provide a variety of useful tools and techniques for hybrid
networks, which may be of independent interest.\r\n"

text: "We consider the clock synchronization problem in the (discrete) beeping model:
Given a network of $n$ nodes with each node having a clock value $\\delta(v) \\in
\\{0,\\ldots T-1\\}$, the goal is to synchronize the clock values of all nodes
such that they have the same value in any round.\r\nAs is standard in clock synchronization,
we assume \\emph{arbitrary activations} for all nodes, i.e., the nodes start their
protocol at an arbitrary round (not limited to $\\{0,\\ldots,T-1\\}$).\r\nWe give
an asymptotically optimal algorithm that runs in $4D + \\Bigl\\lfloor \\frac{D}{\\lfloor
T/4 \\rfloor} \\Bigr \\rfloor \\cdot (T \\mod 4) = O(D)$ rounds, where $D$ is
the diameter of the network.\r\nOnce all nodes are in sync, they beep at the same
round every $T$ rounds.\r\nThe algorithm drastically improves on the $O(T D)$-bound
of \\cite{firefly_sync} (where $T$ is required to be at least $4n$, so the bound
is no better than $O(nD)$).\r\nOur algorithm is very simple as nodes only have
to maintain $3$ bits in addition to the $\\lceil \\log T \\rceil$ bits needed
to maintain the clock.\r\nFurthermore we investigate the complexity of \\emph{self-stabilizing}
solutions for the clock synchronization problem: We first show lower bounds of
$\\Omega(\\max\\{T,n\\})$ rounds on the runtime and $\\Omega(\\log(\\max\\{T,n\\}))$
bits of memory required for any such protocol.\r\nAfterwards we present a protocol
that runs in $O(\\max\\{T,n\\})$ rounds using at most $O(\\log(\\max\\{T,n\\}))$
bits at each node, which is asymptotically optimal with regards to both, runtime
and memory requirements."

text: "We consider congestion control in peer-to-peer distributed systems. \r\nThe
problem can be reduced to the following scenario: Consider a set $V$ of $n$ peers
(called \\emph{clients} in this paper) that want to send messages to a fixed common
peer (called \\emph{server} in this paper).\r\nWe assume that each client $v \\in
V$ sends a message with probability $p(v) \\in [0,1)$ and the server has a capacity
of $\\sigma \\in \\mathbb{N}$, i.e., it can recieve at most $\\sigma$ messages
per round and excess messages are dropped.\r\nThe server can modify these probabilities
when clients send messages.\r\nIdeally, we wish to converge to a state with $\\sum
p(v) = \\sigma$ and $p(v) = p(w)$ for all $v,w \\in V$.\t\r\n\r\nWe propose a
\\emph{loosely} self-stabilizing protocol with a slightly relaxed legitimate state.
\ \r\nOur protocol lets the system converge from \\emph{any} initial state to
a state where $\\sum p(v) \\in \\left[\\sigma \\pm \\epsilon\\right]$ and $|p(v)-p(w)|
\\in O(\\frac{1}{n})$. \r\nThis property is then maintained for $\\Omega(n^{\\mathfrak{c}})$
rounds in expectation.\r\nIn particular, the initial client probabilities and
server variables are not necessarily well-defined, i.e., they may have arbitrary
values.\r\n\r\nOur protocol uses only $O(W + \\log n)$ bits of memory where $W$
is length of node identifiers, making it very lightweight.\r\nFinally we state
a lower bound on the convergence time an see that our protocol performs asymptotically
optimal (up to some polylogarithmic factor).\r\n"

text: "We propose two protocols for distributed priority queues (denoted by 'heap'
for simplicity in this paper) called SKEAP and SEAP. SKEAP realizes a distributed
heap for a constant amount of priorities and SEAP one for an arbitrary amount.
Both protocols build on an overlay, which induces an aggregation tree on which
heap operations are aggregated in batches, ensuring that our protocols scale even
for a high rate of incoming requests. As part of SEAP we provide a novel distributed
protocol for the k-selection problem that runs in time O(log n) w.h.p. SKEAP guarantees
sequential consistency for its heap operations, while SEAP guarantees serializability.
SKEAP and SEAP provide logarithmic runtimes w.h.p. on all their operations. \r\nSKEAP
and SEAP provide logarithmic runtimes w.h.p. on all their operations with SEAP
having to use only O(log n) bit messages."

for self-stabilizing systems from one to multiple dimensions.\r\n\tA system is
self-stabilizing if it can recover to a legitimate state from any initial illegal
state.\r\n\tThese kind of systems are most often used in distributed applications.\r\n\tMonotonic
searchability provides guarantees when searching for nodes while the recovery
process is going on.\r\n\tMore precisely, if a search request started at some
node $u$ succeeds in reaching its destination $v$, then all future search requests
from $u$ to $v$ succeed as well.\r\n\tAlthough there already exists a self-stabilizing
protocol for a two-dimensional topology~\\cite{DBLP:journals/tcs/JacobRSS12} and
an universal approach for monotonic searchability~\\cite{DBLP:conf/wdag/ScheidelerSS16},
it is not clear how both of these concepts fit together effectively.\r\n\tThe
latter concept even comes with some restrictive assumptions on messages, which
is not the case for our protocol.\r\n\tWe propose a simple novel protocol for
a self-stabilizing two-dimensional quadtree that satisfies monotonic searchability.\r\n\tOur
protocol can easily be extended to higher dimensions and offers routing in $\\mathcal

text: "In this paper we present two major results:\r\nFirst, we introduce the first
self-stabilizing version of a supervised overlay network (as introduced in~\\cite{DBLP:conf/ispan/KothapalliS05})
by presenting a self-stabilizing supervised skip ring.\r\nSecondly, we show how
to use the self-stabilizing supervised skip ring to construct an efficient self-stabilizing
publish-subscribe system.\r\nThat is, in addition to stabilizing the overlay network,
every subscriber of a topic will eventually know all of the publications that
have been issued so far for that topic. The communication work needed to processes
a subscribe or unsubscribe operation is just a constant in a legitimate state,
and the communication work of checking whether the system is still in a legitimate
state is just a constant on expectation for the supervisor as well as any process
in the system.\r\n"

text: "We propose a distributed protocol for a queue, called Skueue, which spreads
its data fairly onto multiple processes, avoiding bottlenecks in high throughput
scenarios.\r\nSkueuecan be used in highly dynamic environments, through the addition
of join and leave requests to the standard queue operations enqueue and dequeue.\r\nFurthermore
Skueue satisfies sequential consistency in the asynchronous message passing model.\r\nScalability
is achieved by aggregating multiple requests to a batch, which can then be processed
in a distributed fashion without hurting the queue semantics.\r\nOperations in
Skueue need a logarithmic number of rounds w.h.p. until they are processed, even
under a high rate of incoming requests."

text: 'Searching for other participants is one of the most important operations
in a distributed system.We are interested in topologies in which it is possible
to route a packet in a fixed number of hops until it arrives at its destination.Given
a constant $d$, this paper introduces a new self-stabilizing protocol for the
$q$-ary $d$-dimensional de Bruijn graph ($q = \sqrt[d]{n}$) that is able to route
any search request in at most $d$ hops w.h.p., while significantly lowering the
node degree compared to the clique: We require nodes to have a degree of $\mathcal
O(\sqrt[d]{n})$, which is asymptotically optimal for a fixed diameter $d$.The
protocol keeps the expected amount of edge redirections per node in $\mathcal
O(\sqrt[d]{n})$, when the number of nodes in the system increases by factor $2^d$.The
number of messages that are periodically sent out by nodes is constant.'
