ORGANIZATION OF A DECENTRALIZED AND ANONYMOUS MESH NETWORK

Abstract

As part of this work, proposed the Mesh network architecture, which provides decentralization, security, anonymity and connection of devices without a dedicated router or Internet access. The nodes establish connections directly using Android P2P Wi-Fi technology, which complies with the Wi-Fi Direct standard. P2P Wi-Fi API organizes group communication and allows applications to connect to neighboring devices without the need for an Internet connection or access point. Despite the fact that in the Wi-Fi Direct standard there are no restrictions on connecting groups to each other, the Android Wi-Fi P2P API does not allow organize a connection between several groups. This is due to the fact that the IP addresses of owners of different groups in Wi-Fi Direct are always the same and unchanged. Communication between a P2P client and an inherited client that also owns another group is allowed in both directions. This provides connections between groups, where a P2P client acts as a proxy to access a neighboring group. Thus communication between nodes in a multigroup network is ensured through the use of transport layer tunnels installed in the logical topology and packet switching at the application level. When one or more nodes access the Internet, remote nodes outside the Wi-Fi coverage area communicate with the mesh through the application server. This architecture allows build a corporate, public or home network based on a wireless Mesh network, the nodes of which can be access points, computers and mobile devices of users.
