It combines very low cost Raspberry PI’s running Linux using OLSR to build out a network backbone and Android devices that join the network to run Android apps. The Android app that uses OLSR to achieve this was originally using Version 1 of the protocol. For many good reasons, Version 2 is desired. When using version 1, HNA was utilized for a particular node to alert other nodes that it could use this node to route packets to the Internet. A device that has the WiFi connected to the OLSR adhoc network and has a hardwired Ethernet to the internet is a candidate for this. A phone with a 3G or 4G cellular connection is also such a candidate. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo1'><![if !supportLists]><span style='font-family:Symbol'><span style='mso-list:Ignore'>·<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]>I have Olsrd2 ported to Android and it is running inside an App on the Android devices<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo1'><![if !supportLists]><span style='font-family:Symbol'><span style='mso-list:Ignore'>·<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]>I am using olsrd2_static as it just makes it simpler (at least at this juncture)<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo1'><![if !supportLists]><span style='font-family:Symbol'><span style='mso-list:Ignore'>·<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]>I am using fixed IP addresses on the WiFi for now<o:p></o:p></p><p class=MsoListParagraph style='margin-left:1.0in;text-indent:-.25in;mso-list:l1 level2 lfo1'><![if !supportLists]><span style='font-family:"Courier New"'><span style='mso-list:Ignore'>o<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]>I do really want to have the devices generate their own IP’s as this is a cool version 2 enhancement but haven’t gotten that to work yet.
