Demo Proposal – VoIP for isolated and Internet-connected Mobile Ad Hoc Networks

SIPHoc is a middleware infrastructure for session set up and management in MANETs. SIPHoc is compliant to the SIP standard, does not require any centralized components, is message efficient (through routing message piggybacking), and independent of the routing protocol (currently, SIPHoc supports both AODV and OLSR). Moreover, SIPHoc allows seamless interaction with the Internet by treating nodes connected to the Internet as gateway services and making this information known across the MANET. In this demo we will show how SIPHoc can be used to build a wireless multihop VoIP network. Using iPAQ handhelds, participants of the demo can set up VoIP calls between each other, as well as to and from the Internet if a gateway can be discovered. As part of the demo we will further use a protocol analyzer to show how the SIP contact information is piggybacked onto routing messages, for both AODV and OLSR.
