Hi, Fortain: I think that you can start working for all those QOS mechanisms within the framework of P2PSIP. Let me explain as follows:
1. Mobile Ad Hoc networks need P2P networking. As result, the applications also need to be P2P. P2PSIP WG is working for facilitating in building of P2PSIP applications. 2. The ad hoc mobility part is primarily related to the topology control of MANETs and MANET WG and AUTOCONFIG WG are working in the layers 2-through 3/4. The QOS-mechanisms of the network layer are being taken care of by those WGs. 3. The application layer QOS for SIP in peer-to-peer mode can best be working within the framework of P2PSIP WG because, I believe, you do not need to do anything explicitly related to mobility assuming that the lower MAC and network layer of MANET are being taken care of by those WGs (e.g. topology control, routing, QOS) and we can plug those things from the application layer to the lower network to work cooperatively. 4. It is true that we may have to do something in the P2P application layer like P2PSIP for QOS as well as for taking care of the ad hoc mobility, it is still not well understood by all of us. Once the P2PSIP signaling protocol is taken care of, we will gain more experiences what we have to do next. However, if you suggest what specific problems related to QOS you want to address in the P2PSIP application Layer for solving the performance problems, we can then look into those taking Navy's QOS requirements for MANET networks. I appreciate for bringing the interesting real problems in the P2PSIP WG mailing list.
