Hi,
sorry for the delayed response, I'm pretty busy at the moment…

So, if I create two subnets, the configuration is equal below:
ROUTER 1 DHCP-OLSR: 192.160.1.0/25,255.255.255.0 HNA4: 192.160.1.0/25 IP WIRELESS: 192.160.1.1 MSK: 255.255.255.0
ROUTER 2 DHCP-OLSR: 192.160.1.128/25,255.255.255.0 HNA4: 192.160.1.128/25 IP WIRELESS: 192.160.1.129 MSK: 255.255.255.0
HNA4 should be "0.0.0.0/0" if the router provides an uplink. Leave empty else. OLSR will announce the existing nodes automatically, there is no need to announce this via HNA4 explicitly.
Please try first to setup the mesh without OLSR-DHCP. If this works, add olsr-dhcp.
You should choose a smaller network for the dhcp-range. Recommendation: 192.160.1.32/27 + 192.160.1.64/27 which gives you 30 clients per node.
$ ipcalc 192.160.1.32/27 Address: 192.160.1.32 11000000.10100000.00000001.001 00000 Netmask: 255.255.255.224 = 27 11111111.11111111.11111111.111 00000 Wildcard: 0.0.0.31 00000000.00000000.00000000.000 11111 => Network: 192.160.1.32/27 11000000.10100000.00000001.001 00000 HostMin: 192.160.1.33 11000000.10100000.00000001.001 00001 HostMax: 192.160.1.62 11000000.10100000.00000001.001 11110 Broadcast: 192.160.1.63 11000000.10100000.00000001.001 11111 Hosts/Net: 30 Class C
IP WIRELESS: 192.160.1.32 DHCP-OLSR: 192.160.1.32/27,255.255.255.0 HNA4: MSK: 255.255.255.0

The clients will receive IP's 192.160.1.2 - 192.160.1.127 if is connected Router 1, and 192.160.1.130 - 192.160.1.254 if is connected Router 2.
Well there's a problem in your net masks:
$ ipcalc 192.160.1.0/25 Address: 192.160.1.0 11000000.10100000.00000001.0 0000000 Netmask: 255.255.255.128 = 25 11111111.11111111.11111111.1 0000000 Wildcard: 0.0.0.127 00000000.00000000.00000000.0 1111111 => Network: 192.160.1.0/25 11000000.10100000.00000001.0 0000000 HostMin: 192.160.1.1 11000000.10100000.00000001.0 0000001 HostMax: 192.160.1.126 11000000.10100000.00000001.0 1111110 Broadcast: 192.160.1.127 11000000.10100000.00000001.0 1111111 Hosts/Net: 126 Class C
If you assign 1.1 to the router the IP overalaps with the dhcp-range. A "solution" would be to assign 1.0 to router 1, but this is forbidden (1.0 is the network-IP).
Try my suggested IPs/Netmasks first.

How I do that one router see the other? Since they are on different networks?
They're on the same network: 192.160.1.0/24. Only the dhcp-range is a subset of the OLSR-network range.
