It's possible, but it wouldn't scale well. There are some routing
protocols for ad hoc wireless networks that take that approach:

distributed anonymous routing protocol for wireless and mobile ad hoc
networks. In Proceedings of the 29th Annual IEEE International
Conference on Local Computer Networks (LCN 2004), Tampa, FL, USA,
pages 618–624, November 2004.

source routing for mobile ad-hoc networks. In Proceedings of the ACM
