From scanning the wiki page, looks like it qualifies as a Ad hoc network. The nodes can address each other and there is a routing protocol to route packets in a multi-hop fashion. The wiki page does not talk about mobility. I assume that when nodes move around, it tries to stay connected. -- Bill Cheng // bill.cheng@usc.edu ----- Original Message ----- From: Bill Cheng Date: Thursday, December 4, 2008 12:53 am Subject: Re: Example of Ad-hoc network To: cs551@merlot.usc.edu > Someone wrote: > > > Wouldn't the behavior of the OLPC mesh network be a good example > > of ad-hoc computing? > > > > http://wiki.laptop.org/go/Mesh_Network_Details > > > > When you brought up the subject, the first two things I thought > > of were the military sensor networks, and the > > One-laptop-per-child initiative. > > Are you asking about why the lecture slides said that there > are no non-military *applications*? > > I'm not familiar with the OLPC mesh network.
