Network Protocols

"A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. ...
Depending on whether the diagram is intended for formal or informal use, certain details may be lacking and must be determined from context. ...
At different scales diagrams may represent various levels of network granularity. At the LAN level, individual nodes may represent individual physical devices, such as hubs or file servers, while at the WAN level, individual nodes may represent entire cities. In addition, when the scope of a diagram crosses the common LAN/ MAN/ WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes."

"Zooko's triangle is a diagram named after Zooko Wilcox-O'Hearn which sets out suspected tradeoffs for a system for giving names to participants in a network protocol. At the vertices of the triangle are three properties that are generally considered desirable for such names:
Secure: The quality that there is one, unique and specific entity to which the name maps. For instance, domain names are unique because there is just one party able to prove that they are the owner of each domain name.
Decentralized: The lack of a centralized authority for determining the meaning of a name. Instead, measures such as a Web of trust are used.
Human-meaningful: The quality of meaningfulness and memorability to the users of the naming system. Domain names and nicknaming are naming systems that are highly memorable." [Zooko's triangle. Wikipedia]

"A wireless ad hoc network (WANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre existing infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Instead, each node participates in routing by forwarding data for other nodes, so the determination of which nodes forward data is made dynamically on the basis of network connectivity. In addition to the classic routing, ad hoc networks can use flooding for forwarding data.
Wireless mobile ad hoc networks are self-configuring, dynamic networks in which nodes are free to move. Wireless networks lack the complexities of infrastructure setup and administration, enabling devices to create and join networks "on the fly" – anywhere, anytime." [Wireless ad hoc network.
