2. Terms, Definitions & Useful Links

This page tries to clarify and define the terms and jargons associated the Networking, Mesh, Electromagnetics, etc...... which ever that associates with building a mesh network. Please Link to this page, when explaining "specific things and differences" in other pages - to avoid drifting towards defining the specifics from the crux of the content while explaining in other pages. Useful Links is also included :)

What is the difference between Adhoc and Mesh ?

In wireless networking, Ad-Hoc is one of the modes of operation for an 802.11 radio. It happens at OSI layer 1, the physical layer, and it basically means that all devices can communicate directly to any other device that is within radio range. Normally, in Infrastructure mode, wireless devices can only communicate with a central Access Point or Router and that device is responsible for re-transmitting packets from one client device to another client device (even if they are right next to each other). Ad-Hoc networks get rid of the middle-man that is the AP, however they don’t have any inherent capability for multi-hop. That means, if device A can reach device B, and device B can reach device C, but A cannot reach C, then A and C cannot communicate because B will not re-transmit any packets.

Mesh Networking, also know as Mesh Routing happens at OSI layer 3, the network layer. Mesh Routing allows each device on a network (also called nodes) to act as a router and re-transmit packets on behalf of any other devices. Mesh Routing provide the multi-hop facility that Ad-Hoc mode lacks. By combining Ad-Hoc mode at layer 1 and Mesh Routing at layer 3 we can create wireless mesh networks purely between client devices without any need for centralized Access Points or Routers.

P2P or Peer-to-Peer simply means that clients talk directly to each other without the use of a central server. Both Ad-Hoc and Mesh Routing can be described as P2P as they are both instances of clients-to-client communication, just at different layers of the OSI model.

Ad-hoc networks are multi-hop networks where most nodes are wireless and connections and routes are extremely dynamic as the network builds and changes. retro bowl college
