IMA-DTN
Based on IBR-DTN
This is the guide to setting up simple DTN demo. The demo involves Android device and APs running OpenWRT. Android DTN-App can at least send GPS data to a receiving DTN-App installed on OpenWRT.
Openwrt dev
Install ibrdtn
opkg update opkg list | grep ibrdtn opkg install ibrdtnd ibrdtn ibrdtn-tools
configure the daemon via /etc/config/ibrdtn you have to start/stop it via /etc/init.d/ibrdtn start|stop.
Setup WLAN AP / Ad-hoc
Create WiFi Interface
Edit /etc/config/network and define a new interface section:
config 'interface' 'wlan0'
option 'proto' 'static'
option 'ipaddr' '10.0.0.1'
option 'netmask' '255.255.255.0'
Enable Wireless (disabled by default)
Edit /etc/config/wireless
config wifi-device radio0
option type mac80211
option channel 11
option hwmode 11g
option path 'pci0000:00/0000:00:1c.1/0000:02:00.0/0000:03:07.0/0000:07:00.0'
option htmode HT20
# REMOVE THIS LINE TO ENABLE WIFI:
option disabled 0 <---------- HERE
config wifi-iface
option device radio0
option network wlan0
option mode adhoc
option ssid openwireless.org
option encryption none
Start / Stop Wifi
wifi (up - default) wifi up (devicename) wifi down (devicename)
Regenerate Configuration
To rebuild the configuration file, e.g. after installing a new wireless driver, remove the existing wireless configuration (if any) and use the wifi detect command with stdout redirected to the /etc/config/wireless file:
rm -f /etc/config/wireless wifi detect > /etc/config/wireless wifi detect > /etc/config/wireless
DHCP for WiFi-AP Mode
a new dhcp pool must be defined in /etc/config/dhcp:
config 'dhcp' 'wlan0'
option 'interface' 'wlan0'
option 'start' '50'
option 'limit' '200'
option 'leasetime' '1h'
If DHCP not working, check:
config 'dnsmasq'
list 'interface' 'lan'
list 'interface' 'guest'
Configure WiFi Firewall
config 'zone'
option 'name' 'guest'
option 'network' 'guest'
option 'input' 'REJECT'
option 'forward' 'REJECT'
option 'output' 'ACCEPT'
# Allow Guest -> Internet
config 'forwarding'
option 'src' 'guest'
option 'dest' 'wan'
# Allow DNS Guest -> Router
# Client DNS queries ordinate from dynamic UDP ports (>1023)
config 'rule'
option 'name' 'Allow DNS Queries'
option 'src' 'guest'
option 'dest_port' '53'
option 'proto' 'tcpudp'
option 'target' 'ACCEPT'
# Allow DHCP Guest -> Router
# DHCP communication uses UDP ports 67-68
config 'rule'
option 'name' 'Allow DHCP request'
option 'src' 'guest'
option 'src_port' '67-68'
option 'dest_port' '67-68'
option 'proto' 'udp'
option 'target' 'ACCEPT'
Configure WiFi Bandwidth
Apply changes
Enable the new wireless network
/etc/init.d/network restart
Restart the firewall
/etc/init.d/firewall restart
Restart the DHCP service
/etc/init.d/dnsmasq restart
Start traffic shaping
/etc/init.d/wshaper start
Make traffic shaping permanent
/etc/init.d/wshaper enable

Multicast forwading
With IGMP snooping, multicast forwarding is disabled for bridges. One pure bridge solution is to disable multicast_snooping.
Add the following in /etc/rc.local
echo “0”
> /sys/devices/virtual/net/br-lan/bridge/multicast_snooping
Replace br-lan with your actual bridge interface, sometimes also called br0.
This will forward all multicast packets to all ports on your bridge, making igmpproxy or udpxy unnecessary. In large networks, this may not be desirable.
How to add iptables rules???

OpenWRT App dtnimarecv
This DTN-App receives GPS data from Smartphone and forward the data to GPSInfo-Agent on platform. The communication to GPSInfo-Agent is simple TCP, which can be later replaced by more advanced method e.g., ICN.
Source on Fedora
Copy apps from “ibrdtn/tools” as starting:
cp -rp $ibrdtn_repo/ibrdtn/tools $ibrdtn_ws/ibrdtn_imaapp cd $ibrdtn_ws/ibrdtn_imaapp
Prepare source for dtnimarecv app:
cp src/dtnrecv.cpp src/dtnimarecv.cpp vim Makefile.ac # search for dtnrecv and copy to dtnimarecv ./autogen.sh
Compile source:
./configure --help ./configure --prefix=/home/dang/data/src/01_ima_ws/60_ibr_dtn/ibrdtn-prefix --with-ibrcommon=/home/dang/data/src/01_ima_ws/60_ibr_dtn/ibrdtn-repo/ibrcommon --with-ibrdtn=/home/dang/data/src/01_ima_ws/60_ibr_dtn/ibrdtn-repo/ibrdtn/ibrdtn <---- NOTE: ibrdtn_src make install OK...
Test
Start dtnd and dtnimarecv:
cd $ibrdtn_ws source ibrdtn-env.rc dtnd -c ibrdtnd.conf -i wlp3s0: -d 9 dtnimarecv --name gps
Start Android IMADTNApp with dest set to “dtn:\/\/localhost.localdomain\/gps”
Sent Lon/Lat from Android
Observe on dtnimarecv console:
dtnimarecv --name gps Lat:52.512808Lon:13.322360
Creating OpenWRT app
