Consider Infrastructure
	For high-density networks, you want: no base stations no distinction between routers and nodes infrastructure created simply by adding nodes

So what it comes down to is that to create a high-density network, the routing of packets and the maintenance of the network must be fully distributed with no distinction between a "router" and a "terminal node."

One reward of this architecture is that the creation of the initial infrastructure is almost free. All you need to create a network is to scatter enough nodes around so that they can hear each other. If you don't have sufficient coverage at some place in the network, you simply reach into your bag of nodes and stick another on the wall.
