Opportunistic routing in wireless networks has been proposed as a method to combat the volatility of wireless links, by leveraging their broadcast nature and choosing the next hop for each transmitted packet post-facto, using the actual reception outcomes at the respective neighbors, rather than based on a priori information. Much of the research on the topic has focused on protocol design issues, e.g. coordination mechanisms among the next-hop candidates; however, the fundamental performance bounds of the scheme are not yet known.
