The router is the "host". Most routers will do what you want "out of
the box"; since they have DHCP enabled. With DHCP enabled; computers
are able to connect to the router either wired or wireless. All
computers that obtained their ip address from the same router will be
able to communicate with each other.
Any consumer grade UPS that is designed to run a desktop system for
15-30 minutes will run a router for several hours. A DC/AC converter
connected to your vehicle's lighter outlet will easily turn that vehicle
into a generator.
What kind of communication are you expecting bewteen these connected
computers? You won't need email since the range of wireless signal on
routers is so low you can more easily use verbal communication to speak
to the other party. For long range communication, the trick will be to
get multiple routers connected to each other! That's normally what the
internet does - without telephone or internet support, it won't be so easy.
