  Today's Internet is heavily used for multimedia streaming from cloud
backends, while the Internet of Things (IoT) reverses the traditional data
flow, with high data volumes produced at the network edge. Information Centric
Networking (ICN) advocates against a host-centric communication model which is
promising for distributed edge computing environments and the execution of IoT
applications in a decentralized fashion. By using naming schemes, data is
tightly coupled to names instead of hosts which simplifies discovery and access
to data and services. However, the tight coupling challenges network
performance due to additional synchronization overhead of large data volumes
and services. We present Tangle Centric Networking (TCN) -- a decentralized
data structure for coordinated distributed applications and data exchange
following principles of ICN. TCN can react on data and service changes and
update them accordingly in network nodes, provide distributed data structures
and enable cooperative work on the same data without huge overhead by using
Tangles for coordination. We implemented TCN in simulations and evaluated the
concept against a base line scenario.
