Abstract—We present and evaluate new ROS packages for
coordinated multi-robot exploration, namely communication,
global map construction, and exploration. The packages allow
completely distributed control and do not rely on (but allow)
central controllers. Their integration including application layer
protocols allows out of the box installation and execution. The
communication package enables reliable ad hoc communication
allowing to exchange local maps between robots which are
merged to a global map. Exploration uses the global map
to spatially spread robots and decrease exploration time. The
intention of the implementation is to offer basic functionality for
coordinated multi-robot systems and to enable other research
groups to experimentally work on multi-robot systems. The
packages are tested in real-world experiments using Turtlebot
and Pioneer robots. Further, we analyze their performance using
simulations and verify their correct working.

Replication and replacement in dynamicdelivery networks
Purpose: Content delivery in dynamic networks is a challenging task, because paths
may change during delivery and content might get lost. Replication is a typical
measure to increase robustness and performance.
Method: In previous work we proposed a hormone-based algorithm that delivers
content, and optimizes the distribution of replicas. Clients express demands by
creating hormones that will be released to the network. The corresponding resources
are attracted by this hormone and travel towards a higher hormone concentration. This
leads to a placement of content close to their most frequent requesters. In addition to
that the hormone-based delivery requires an appropriate replication and clean-up
strategy to balance the replicas throughout the network without exceeding the nodes’
storage limits or the networks communication capacity.
