Attempts to resolve the issues related to naming/addressing, middle boxes, QoS-Security-Mobility interactions, cross-layer and inter-domain usually lead to endless debates. This is because the structure of the Internet has become too complex and has evolved with new functions added which are not always compatible with the existing functions. In order to analyze the architecture of the Internet in a strict manner, it is necessary to understand in depth the composition of functionalities within a protocol or between protocols. This paper presents a study on the composition of network functionalities and highlights future directions towards a theory for network architectures which includes the principles that network architectures should follow to ensure the normal operation of the member functions, detect all possible conflicts between them as well as figure out impossibilities.

Blockgraph has been designed to enable the use of blockchain in mobile ad hoc networks and mesh networks by dealing with the problem of network partition due to node mobility. This paper presents a proof of the blockgraph concept using a testbed composed of five mesh routers. The demonstration shows that the blockgraph is created and maintained by the participant nodes in case of network split and merge. CCS CONCEPTS • Networks → Network architectures; Mobile networks.

In this paper, we demonstrate that D2D communications can also be used to offload the Wi-Fi access point in a dense wireless network. Wi-Fi Direct, a popular wireless technology available in tablets and smartphones, is used to realize D2D communications. Clustering , power control and transmission scheduling techniques are applied to optimize the network performances. The simulation results show that a significant performance gain can be obtained with a download time reduction up to 30%.
