Recently, there have been papers indicating that the maximal ratio combiner device can result in energy savings in wireless ad hoc networks by using Hitch-hiking. We study the Min-Energy Broadcast with Hitch-hiking problem, an idealized version of broadcast using hitch-hiking, a problem studied experimentally in the INFOCOM 2004 paper of Agarwal et. al. Min-Energy Broadcast with Hitch-hiking captures the maximum savings one can achieve in broadcasting using maximal ratio combiners. We show that the optimum of the classical Min-Energy Broadcast problem is at most O(log2 n) times the optimum of Min-Energy Broadcast with Hitch-hiking, where n is the number of nodes in the networks. We show that this bound is tight up to a constant. Moreover, the same bounds hold for Unicast.
