Exploiting mobility in multihop infostation networks to decrease transmit power

Mobility, rather than being a liability, can be an asset. If delay constraints are loose, it is possible for a given packet to observe many different network topologies as nodes move relative one another, and these different topologies can be treated as diversity. Opportunistic strategies can exploit these large scale changes in the channel quality to decrease transmit power at the expense of greater delay. We study the tradeoff between mobility, transmit power and delay and along the way develop simple greedy (packet-based) threshold rules for packet transmission.
