Target of The Project
Efficient mesh network for Smart mobile phone
user.
By implementing a Distributed Universal Number
Discovery system adding more mobile device on
the network.
Improving a call quality.
DESIGN OVERVIEW OF THE PROJECT
Front End Application
Distributed Universal Number Discovery.
Routing Protocol.
Design Interaction Between Mesh Potato and Smartphone
1. ssh/telnet MP
2. Configure DUNDi.conf
3. Configure MP WLAN
Smartphone
Distributed Universal Number
Discovery (DUNDi) Configuration
6. Make a phone call /Receive a call
5. Adding Smartphone
to Mesh Network
Mesh Potato and WLAN setup
4. Configure Smartphone APP
How Does DUNDi Work?
Think of DUNDi as a large phone book that allows
you to ask peers if they know of an alternative
VoIP route to the Destination Phone
Checking the nearest path by sending CRC to
the connected MPs
User Interface of SIPDroid Softphone
SIPDroid Application is a free Google Android ® Application software ,
design for both smartphone and PC

Web based User Interface of Mesh Potato
It allow us to configure IP security of the mesh network

LOW LEVEL DESIGN
e.g. Configuring Mesh Potato Node Interfaces to implement DUNDi
The following Steps help to configure each Mesh Nodes:
 Use MP Wi-Fi devices like ethX and also common ethernet devices,
usually ethX. Note X can be 0 and 1
 Mesh Node interfaces added using 'batctl if add ifname', e.g. batctl if
add eth0
 Installing .ipk files to implement DUNDi and finally change the
configuration file of each mesh potato.
LOW LEVEL DESIGN
e.g. Changing .conf files value
 ssh into the MP
Move through cd /var/lib/asterisk/keys
‘ls’ to check availability of the files
Change the values of IAX.CONF ,DUNDI.conf and Extention.conf files
 ‘vim’ the files to change default values
LOW LEVEL DESIGN
Pseudocode
Start_calling()
If phone_numer != registerd then
Phone_number= registerd;
else
search_MP=the_nearest_MP(MP_number);
search_phone_number=dialed_phone_number(Phone_number);
if the_nearest_MP(MP_number) = store(phone_number) then
send_signal();
else
search_Next_MP()
if store(phone_number) = 1 && phone_line!=busy then
accepet_call();
else
terminate_call();
end
