Mesh networking on OpenWRT 15.05 with OLSR

DOCUMENT UNDER CONSTRUCTION.

Preliminaries

Software

OpenWRT 15.05 Chaos Calmer is installed with defaults. Target device as 8Mb Flash Memory Minimum.

Hardware

Note concerning the WR703N router. This must be modified with upgraded flash memory. The default unit does not have sufficient memory.

This will work on EmonWRT3 and ModWRT devices.

Setup a Node

This is for setting up a simple node that has no access to the outside but can connect to other nodes. Most unit in the network will have this configuration.

We will use here

• Wired - Static IP 192.168.2.1 (for configuration access only)
• Wifi - Ad-hoc wifi with Static IP 10.10.10.xx

-1-

First of all make sure the wired interface LAN is setup with static IP address. For our example we will use 192.168.2.1 but you might choose any other private IP that you like. Note that you should avoid the 192.168.1.0 network.
