Or "created on |the |> spur of the moment, impromptu" (http://en.wiktionary.org/wiki/ad_hoc). | |Along these lines, an interpretation of 'ad-hoc' is a happening which |hasn't been planned, spontaneous, etc. This would contradict the goal |of planning an addressing architecture for it, unless the limits of |movement and the characteristics of the underlying link-layers are |noted. There is a difference in a) designing and building a network, ready for deployment and b) planning for actual deployment. In military, actual deployment does not occur quite often (luckily!), but it is exercised repeatedly. For public safety / disaster relief, the network is often in use for normal conditions (no disaster), here we may have restrictions as you suggest. But as soon as there is a disaster (small, large), the conditions may no longer be true. Here also, the large disasters do not occur frequently. But if it occurs, damage can be huge. For both use cases (military and disaster relief), the requirement is that the network provides as much connectivity as technically possible, also in unforeseen conditions. Sorry to bother you with one of the major requirements I am facing, and I am sure I am not the only one. As said, MANET is being worked on for many years and actually being deployed. I described the difference in designing and planning deployment. For designing the network, we need components that have certain characteristics, e.g. working well in an ad hoc (unplanned) fashion. IMHO this means, that when a radio link works well over 25 meter, and it is being used in 30 meter or an obstacle breaks the link or makes it uni-directional (see my diagrams for details), the network may not melt down. Connectivity should restored using alternative paths if available and feasible. Let's go on with refinement an address model for MANETs. This is more important than quarreling on 25m or analyzing wording, I think. Teco. | |Alex
